This book was released on 2012-04 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: To investigate the effect of non-ionic polymers polyvinyl pyrrolidone (PVP), polyethylene oxide and polyvinyl alcohol on critical micelle concentration of an anionic surfactant, sodium dodecyl sulfate and a cationic surfactant, cetyltrimethyl ammonium bromide at different temperatures by conductivity and surface tension techniques. The CMC of SDS decreased in presence of the polymers. The degree of this decrease in CMC of SDS was greater for PVP than for PEO and PVA. Increase in the micellar ionization degree was observed for SDS-polymer mixtures. Gcomp values for SDS-polymer mixtures were higher, more negative for SDS-polymer mixtures than pure SDS. These results showed that as compared to PEO and PVA, PVP interacts more strongly with SDS. The critical aggregation concentration of SDS-PVP, SDS-PEO and SDS-PVA mixtures slightly decreased with rise in temperature. and Gcomp of SDS-polymer mixtures increased with increase in temperature reflecting that complexation is favored at high temperatures. The krafft temperature of CTAB did not show any dependence on the concentration of the polymers.

This book was released on 2013-06-29 with total page 367 pages. Available in PDF, EPUB and Kindle. Book excerpt: To the biochemist, water is, of course, the only solvent worthy of consideration, because natural macromolecules exhibit their remarkable conformational properties only in aqueous media. Probably because of these remarkable properties, biochemists do not tend to regard proteins, nucleotides and polysaccharides as polymers in the way that real polymer scientists regard methyl methacrylate and polyethylene. The laws of polymer statistics hardly apply to native biopolymers. Between these two powerful camps, lies the No-man's land of water soluble synthetic polymers: here, we must also include natural polymers which have been chemically modified. The scientific literature of these compounds is characterized by a large number of patents, which is usually a sign of little basic understanding, of 'know-how' rather than of 'know-why'. Many of the physical properties of such aqueous solutions are intriguing: the polymer may be completely miscible with water, and yet water is a 'poor' solvent, in terms of polymer parlance. ~kiny of the polymers form thermorever sible gels on heating or cooling. The phenomena of exothermic mixing and salting-in are common features of such systems: neither can be fully explained by the available theories. Finally, the eccentric behaviour of polyelectrolytes is well documented. Despite the lack of a sound physico-chemical foundation there is a general awareness of the importance of water soluble vinyl, acrylic, polyether, starch and cellulose derivatives, as witnessed again by ~he vast patent literature.

This book was released on 2009-10-01 with total page 628 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water soluble polymers cover a wide range of highly varied families of products of natural or synthetic origin, and have numerous uses. A water soluble polymer is a polymer that can be diluted in water, with or without the assistance of co solvents and neutralizing agents, to form transparent solutions. They may be classified into two types, totally synthetic polymers and natural products together with their chemically modified derivatives and further can be grouped into three main headings; naturally occurring, semi synthetic and completely synthetic polymers. The water based polymers are quick drying non inflammable, having mild odour and more environmentally acceptability than any other polymers. Most conventional coating polymers at present can be produced in a form that will allow them to be solubilized in water. These include alkydes, polyesters, acrylics epoxies. There are various types of polymerization methods of water soluble polymers such as bulk polymerization, solution polymerization, copolymerization, emulsion polymerization and suspension polymerization. Water soluble polymers are used widely as stabilizers or protective colloids in emulsion polymerization. Its most common use are gum acacia, starch either etherified or in its degraded form, dextrin, polyvinyl alchohol and hydroxyethyl cellulose. Polymers find many applications in oil recovery and production, including areas such as; drilling fluids, cementation of well bore, reservoir fracturing, controlling fluid flow in the reservoir and multistage processes of oil production and refining. The water soluble polymers market encompasses several categories, including starch, cellulose ethers, polyvinylacetate, polyvinyl alcohol and other synthetic water soluble polymers. The starch market is the largest. This book basically deals with flow characteristics of water soluble polymer solutions, emulsion polymerization, water reducible resins, silicone modified alkyds and polyesters, cross linking of water soluble coatings, formulation of water soluble coatings, trouble shooting with water soluble polymers, acrylic solution resins, polyvinylpyrrolidone, commercial uses: compounding and formulating adhesives, methods of polymerization, methods for polymerization of acrylamide, fabrication of water soluble polymers, excluded volume interactions of neutral polymers etc. The book covers classification of water soluble polymers, processes, properties, uses and applications of water soluble polymers with lot of other information. This book will be very resourceful for new entrepreneurs, existing units, technocrats, researchers and technical libraries.

Download or read book Surfactants and Polymers in Aqueous Solution written by Krister Holmberg and published by Wiley. This book was released on 2002-11-22 with total page 562 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many industrial formulations such as detergents, paints, foodstuff and cosmetics contain both surfactants and polymers and their interaction govern many of the properties. This book is unique in that it discusses the solution chemistry of both surfactants and polymers and also the interactions between the two. The book, which is based on successful courses given by the authors since 1992, is a revised and extended version of the first edition that became a market success with six reprints since 1998. Surfactants and Polymers in Aqueous Solution is broad in scope, providing both theoretical insights and practical help for those active in the area. This book contains a thorough discussion of surfactant types and gives information of main routes of preparation. A chapter on novel surfactants has been included in the new edition. Physicochemical phenomena such as self-assembly in solution, adsorption, gel formation and foaming are discussed in detail. Particular attention is paid to the solution behaviour of surfactants and polymers containing polyoxyethylene chains. Surface active polymers are presented and their interaction with surfactants is a core topic of the book. Protein-surfactant interaction is also important and a new chapter deals with this issue. Microemulsions are treated in depth and several important application such as detergency and their use as media for chemical reactions are presented. Emulsions and the choice of emulsifier is discussed in some detail. The new edition also contains chapters on rheology and wetting. Surfactants and Polymers in Aqueous Solution is aimed at those dealing with surface chemistry research at universities and with surfactant formulation in industry.

Download or read book Water Soluble Synthetic Polymers written by Philip Molyneux and published by CRC Press. This book was released on 2018-04-05 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although several monographs and reviews have appeared on individual polymers of this type, and their applications and other technical aspects have also been discussed, this is apparently the first book to deal with the physical chemistry of water-soluble synthetic polymers as a group. This collective survey enables their properties and behaviour to be compared, and to be correlated with their molecular structures for predictive purposes. However, this has made it necessary to critically re-appraise much of the earlier fundamental work, so that current discussion of more recent work can be put on ta proper basis. Thus, of the 1800 or so references cited, the middle two-thirds related to the twenty-year period centred on about 1968. Nevertheless, sufficient key recent references have also been included so that the existing ‘state of the art is delineated.

Download or read book Surfactants in Solution written by K.L. Mittal and published by Springer Science & Business Media. This book was released on 2013-03-08 with total page 693 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume chronicles the proceedings of the 8th International Symposium on Surfactants in Solution (SIS) held in Gainesville, FL, June 10-15, 1990. This series of symposia have been smoothly running since 1976, but the appellation "Surfactants in Solution" was used for the first time in 1982 in Lund. Since then our logo "SIS" has become very familiar to everyone involved in surfactants. In Lund the meeting was billed as the Fourth International Symposium on Surfactants in Solution. Earlier three events were held under different rubrics, but proceedings of all these symposia, except the 7th SIS held in Ottawa in 1988, have been properly documented. As a matter of fact so far 10 volumes have appeared under the title "Surfactants in Solution". 1,2,3 The program for the 9th SIS was very comprehensive and many ramifications of surfactants were covered, and it was a veritable international event. It contained a total of 384 papers by 869 authors from practically every corner of our planet. Just the sheer number of papers is a testimonial to the high tempo of research and tremendous interest in this wonderful class of materials. As in the past, there were plenary lectures (5), invited talks (37), oral presentations (195) and poster presentations (147). The plenary lectures were given by Prof. J. Th. G. Overbeek, Prof. C. A. Bunton, Prof. H. Ti Tien and Dr. J. Swalen. The lecture by Prof. Overbeek, the doyen of surface and colloid science, was a real treat.
