Available in PDF, EPUB and Kindle. Book excerpt: Seeded emulsion polymerizations of styrene using the conventional surfactant SLS, TREM LF-40, and poly(TREM) were investigated and compared. The reaction rate decreased using TREM LF-40 and poly(TREM), compared to SLS. For TREM LF-40, it is explained by its participation in copolymerization and/or chain transfer reactions. For poly(TREM), the proposed reason is the formation of a 'hairy' adsorbed layer on the particles, which acts as a barrier decreasing the diffusion of the radicals into and out of the particles. Further, evidence was provided by the molecular weight of the polymer formed. A model for the seeded emulsion polymerization of styrene was developed and the modeling results are consistent with the experimental data using SLS, poly(TREM) and TREM LF-40. All the above results were found to be consistent with each other.

Download or read book Surfactants in Polymers Coatings Inks and Adhesives written by David R. Karsa and published by CRC Press. This book was released on 2020-01-16 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface active agents are used as process aids in the production of polymers--as additives to impart or modify polymer properties--and in the formulation and further processing of polymeric systems for a variety of applications. In all these uses, the surfactants are used as 'effect chemicals,' to impart specific performance characteristics or properties to the base polymer or to enhance it performance when formulated for a specific end use. This volume focuses on those surfactant areas incorporating the greatest number of supplier and user companies. Authors have been selected from leading industrial and academic laboratories around the world. It provides an introduction to the underlying chemistry and technology in these industrial areas, and at the same time, highlights important recent developments. Surfactants in Polymers, Coatings, Inks and Adhesives is a book for surfactant researchers and for manufacturers and users of surfactants. In particular, surfactant chemists, analytical chemists, environmental chemists, users of surfactant formulations in the fields of specialty chemicals, polymers, and detergents, and health and safety personnel.
Download or read book Emulsion Polymerization and Its Applications in Industry written by V. I. Eliseeva and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a large body of Soviet work on emulsion polymerization, spanning a period of over three decades, that has been published primarily in the Russian language. Most of this has remained untranslated into English and hence un available to most other scientists. The value of this book lies primarily in the fact that it brings together the most important of these Soviet contributions, along with comment and analysis by the authors, who may be considered among the foremost authorities in this field in the Soviet Union. But the hundreds of literature citations go far beyond the borders of the Soviet Union and serve as an excellent bibliography of the world literature on emulsion polymerization up to the time this book was written. The book covers both fundamental and applied aspects. In the former are included discussions of particle formation mechanisms, a comprehensive theory of emulsion polymerization, copolymerization of polar monomers, and particle morphology and its implications with regard to derived film properties. Among the applied aspects are discussions of continuous emulsion polymerization, both tubular reactors and continuous stirred tank cascades, and various aspects con cerning the manufacture of some of the most important monomers, such as styrene, butadiene, vinyl acetate, methyl methacrylate, acrylonitrile, and chloroprene. This book will be an indispensable reference source for scientists who are entering the field as well as those who are experienced and who have wanted a ready access to this large body of literature.

Download or read book Polymer Nanocomposites by Emulsion and Suspension Polymerization written by Vikas Mittal and published by Royal Society of Chemistry. This book was released on 2010-09-30 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polymer nanocomposites revolutionized research in the composites area by achieving the nanoscale dispersion of the inorganic filler (clay platelets) in the polymer matrices after suitable surface modifications of the filler phase. A large number of polymer matrices were tried and nanocomposites with varying degrees of successes were achieved with these polymer systems. The majority of the synthesis are carried out by melt blending which frequently result in the full exfoliation of the filler. However, advanced techniques provide a number of advantages as compared to the melt blending and lead to more uniform composites with enhanced properties. There are a number of recent advances in these methods such as the use of reactive surfactants, modified initiators, advanced clay surface modifications, use of a variety of fillers, inverse polymerization, and miniemulsion polymerization methods which have further led the generation of advanced exfoliated nanocomposites. Until now, most of the published research has been scattered throughout the literature. This book provides a single comprehensive source of information about one of the most important facets of polymer nanocomposites technology: synthesis in emulsion and suspension. These polymerization methods lead to the generation of the well delaminated polymer nanocomposites with a wide range of polymer matrices. This book serves as both a professional reference for experienced researchers and a valuable text for newcomers to the field. It makes the reader aware of the potential commercial use of these recent developments.
Download or read book Surfactant Free Emulsion Polymerization of Poly styrene co methyl Methacrylate written by Samantha Applin and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Polymeric microspheres have been used in a broad range of applications from chromatographic separation techniques to analysis of air flow over aerodynamic surfaces. The preparation of microspheres from many polymer families has consequently been extensively studied using a variety of synthetic approaches. Although there are a myriad of polymeric microsphere synthesis methods, free-radical initiated emulsion polymerization is one of the most common techniques. In this work, poly(styrene-co-methyl methacrylate) microspheres were synthesized via surfactant-free emulsion polymerization. The effects of the co-monomer composition and addition time on particle size distribution, particle formation, and particle morphology were investigated. Particles were characterized using dynamic light scattering and scanning electron microscopy to gain further insight into particle size and size distributions. Reaction kinetics were analyzed through consideration of characterization results. A particle formation mechanism for poly(styrene-co-methyl methacrylate) microspheres was proposed based on characterization results and known reaction kinetics.

This book was released on 2012-12-06 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is particularly appropriate that this symposium on the emulsion polymeriza tion of vinyl acetate was held in recognition of the industrial importance of poly(vinyl acetate) and vinyl acetate copolymers, and their rather unique properties among emulsion polymers in general. Poly( vinyl acetate) latexes were the first synthetic polymer latexes to be made on a commercial scale: their production using polyvinyl alcohol as emulsifier began in Germany during the mid-1930s and has continued to the present day, growing steadily with the years. Indeed, poly(vinyl acetate) latexes prepared with polyvinyl alcohol are still one of the mainstays of the adhesives industry. With the passing of time, however, vinyl acetate copolymers have been developed: copolymers with maleate esters such as dibutyl maleate, acrylate esters such as ethyl acrylate and butyl acrylate, versatic acid esters, and, more recently, ethylene. These versatile copolymers have found increasing use in more sophisticated adhesives with specialized properties, adhesives for clay coatings on paper, carpet backing, and interior and exterior paints. Thus more than 45 years after the first commercial production of vinyl acetate latexes, their use is still growing, both in actual quantities and different applications. The industrial importance of vinyl acetate latexes makes the mechanism and kinetics of their emulsion polymerization of practical as well as scientific interest.
