Download or read book Physicochemical Behavior and Supramolecular Organization of Polymers written by Ligia Gargallo and published by Springer Science & Business Media. This book was released on 2009-02-18 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the title suggests, this monograph features the physicochemical behavior and supramolecular organization of polymers. The book consists of four chapters dealing with solution properties, viscoelastic behavior, physicochemical aspects at interfaces and supramolecular structures of polymeric systems. The classical treatment of the physicochemical behavior of polymers is presented in such a way that the book will meet the requirements of a beginner in the study of polymeric systems in solution and in some aspects of the solid state, as well as those of the experienced researcher in other types of materials. Physicochemical behavior and Supramolecular Organization of Polymers is ultimately, a contribution to the chemistry of materials; it is a powerful reference tool for students and scientists working both in polymer chemistry, polymer physics and materials science.

Available in PDF, EPUB and Kindle. Book excerpt: Many factors are known to affect the morphology and properties of ionomers, and the role that the cation local environment plays is not well understood. To better understand ionomer morphology, the cation environment in sulfonated and carboxylated ionomers was investigated using 23Na NMR. As many as three environments were seen in polydisperse sulfonated polystyrene (NaSPS): isolated sodium ions at 7 ppm, hydrated ions at 0 ppm, and aggregated ions at -12 to -23 ppm. In monodisperse NaSPS, a fourth peak at -2.7 ppm appeared at ionization levels above 1.2% and molecular weights of at least 35,000. The fraction of sodium ions held in isolated ion pairs decreased to zero while the fraction of ionic species in aggregates increased with increasing sulfonation. As the neutralization level increased, the aggregate peak shifted to higher frequency with incorporation of neutralizing NaOH. These peak positions and trends are explainable in terms of the magnetic and electric field properties of each Na+ environment.

Download or read book Structure and Properties of Ionomers written by Michel Pineri and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 579 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ionomers, that is polymers containing a low concentration of charged units along the chain, have been the subject of increasing interest during the past twenty years. The presence of ionic groups in the poly mer changes some of its properties dramatically. Increases in the modu lus and the viscosity of several orders of magnitude have been observed, and changes in the glass transition of hundreds of degrees are possible. In addition, diffusion coefficients can be modified drastically. These changes are due primarily to the presence of reversible ionic cross links in these materials. Because of the low dielectric constant of most organic polymers, the ions or ionic dipoles tend to aggregate ; this aggregation process, however, is limited, because the ionic groups are covalently bonded to the organic chain. Host of the fundamental research done on these materials has been devoted to a determination of the extent of association, the structure of the aggregates, the limi ting factors, and the correlations between molecular and supermolecular structure and the resul ting properties.

Download or read book Surfactants and Cosolvents for NAPL Remediation A Technology Practices Manual written by Donald F. Lowe and published by CRC Press. This book was released on 1999-03-26 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: A $19.3 million Department of Defense grant to Rice University funds the Advanced Applied Technology Demonstration Facility (AATDF). One of the project goals is the development of reduction strategies for nonaqueous phase liquids (NAPLs) in the subsurface. Surfactants and Cosolvents for NAPL Remediation records the results of AATDF research. The manual is a guide to the practical application of surfactants/cosolvent for in situ remediation. It is targeted to decision makers and anyone concerned with the design or implementation of these technologies. The book discusses the situational viability of surfactants/cosolvents , the possible results, design, and operation. It includes case studies, step-by-step guidance, and project cost work sheets. The successful results of the AATDF research, as documented Surfactants and Cosolvents for NAPL Remediation, are an invaluable contribution to the future of subsurface remediation. Without source NAPL reduction, the alternative is decades of plume management through pump-and-treat.

Available in PDF, EPUB and Kindle. Book excerpt: Supercritical Fluid Extraction is a technique in which CO2 is used under extremely high pressure to separate solution (e.g., removing caffeine from coffee). Separations is basic to all process industries and supercritical fluid extraction is a specific type which is receiving a high level of attention. The book will combine basic fundamentals with industrial applications. The second edition has been expanded and updated and includes new chapters on chromatography and food processing. "...this is an excellent book which is both instructive and amusing to read. Its true value is neatly summarised in one of the closing sentences: 'We have supplied you with the guidelines and criteria which you can now apply when considering supercritical fluids for your own needs.'' - Chemistry in Britain, February 1995
