Book Description
This monograph is a follow-up material to the first FRRPP book by Gerard Caneba in 2009. It includes additional conceptual results, implementation of the FRRPP process in emulsion media to produce various block copolymers, and other FRRPP-related supplementary topics. Conceptual topics include the application of the quantitative analysis presented in the first FRRPP monograph for the occurrence of the FRRPP process to the polysterene-styrene-ether (PS-S-Ether) and poly(methacrylic acid)-methacrylic acid-water (PMAA-MAA-Water) systems, as well as extensions through unsteady state analysis of the occurrence of flat temperature profiles. Also, the generalization of the quantitative analysis is done to consider molecular weight effects, especially based on changes of the phase envelope to an hourglass type. Topics in implementation of the FRRPP process from pre-emulsions of monomers and the solvent/precipitant are highlighted. Additional FRRPP topics are included in this monograph that pertain to more recent efforts of Gerard Caneba, such as oil spill control, oil dispersant system, and caustic sludge remediation from emulsion-based FRRPP materials, hydrolysis of vinyl acetate-acrylic acid-based copolymers, and other polymer modification studies from FRRPP-based emulsions.

Book Description
Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volumes were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 39 (thesis year 1994) a total of 13,953 thesis titles from 21 Canadian and 159 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 39 reports theses submitted in 1994, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.

Book Description
The IUPAC-sponsored International Symposium on "Radical Polymerization: Kinetics and Mechanism" was held in Il Ciocco (Italia) during the week September 3-8, 2006. It was the fourth within the series of so-called SML conferences, which are the major scientific forum for addressing kinetic and mechanistic aspects of free-radical polymerization and of ontrolled radical polymerization. Top international authors like K. Matyjaszewski, T. P. Davis, T. Fukuda and others present their latest research. The five major themes covered were: Fundamentals of Free-Radical Polymerization, Heterogeneous Polymerization, Controlled Radical Polymerization, Polymer Reaction Engineering, and Polymer Characterization. SML IV again marked an important step forward toward the better understanding of the kinetics and mechanism of radical polymerization, which is extremely relevant for both conventional and controlled radical polymerization and for people in academia as well as in industry.

Book Description
Homo- and co-polymers of acrylamide (AAm) and acrylic acid (or acrylate salt) (AA) or methacrylic acid (MAA)) are important classes of water-soluble polymers due to their numerous applications in fields such as super absorbents, additives in cosmetics, membrane technology, waste-water treatment and oil field operations. These polymers are generally made by free radical polymerization. For copolymerization reactions it is extremely important to know the details of reaction kinetics in order to ascertain the kinetic effects of different reaction parameters, which ultimately dictate final copolymer composition, microstructure and properties. The reactivity ratios for copolymerization of AAm and AA have been shown to be dependent on pH and they also change with reaction solvent. The present experimental investigation has been performed to study the kinetics of copolymerization of these monomers in aqueous and alcoholic media by considering factors such as type of initiator and solvent, and pH, in order to determine how they affect the reactivity ratios of these monomers. Reactivity ratios were determined by non-linear least squares (NLLS) and the error-in-variables-model (EVM) techniques and full conversion range kinetic investigations were carried out to confirm these values.

Book Description
The radical polymerization of methacrylic acid, acrylic acid and acrylamide in aqueous solution has been investigated. Detailed kinetic models for both acrylic acid, AA, and methacrylic acid, MAA, have been developed applying the program PREDICI. Good representation of experimental conversion vs. time profiles and molar mass distributions as well as, in case of AA, the branching level could be achieved. The polymerization of MAA has been studied at 35 and 50 °C with focus on the influence of 2-mercaptoethanol, ME, as chain transfer agent, CTA, on reaction kinetics. The rate coefficient of t ...
