1st Edition
Vinyl Acetate Emulsion Polymerization and Copolymerization with Acrylic Monomers
The versatility of the emulsion copolymerization reaction and the ability to control the properties of the final latices have led to rapid expansion both in the quantity of polyvinylacetate and vinyl acetate-acrylic copolymer latices and in their applications. Vinyl Acetate Emulsion Polymerization and Copolymerization with Acrylic Monomers provides a collection and logical organization of the published data - much of it formerly found fragmented throughout various journals and little of it referenced in general emulsion polymerization books. To date, no one source has offered chemists and polymer, surface, or colloid specialists the "big picture" of polyvinylacetate-based latices.
Integrating established knowledge with the latest research developments, this book provides the background for understanding the mechanism and kinetics of emulsion polymerization initiated in the aqueous phase and some of the practical problems of latex production. The author presents an overview of industrial practices, new applications, and all of the fundamental material - avoiding theoretical controversies.
With in-depth discussion of the ingredients found in most industrial recipes, Vinyl Acetate Emulsion Polymerization and Copolymerization with Acrylic Monomers helps eliminate costly and time-consuming "trial and error" practices. It serves not only as an introduction for those new to the field, but also as a valuable reference for researchers and applied scientists in both industry and academia.

Biography
Yildirim H. Erbil
"It covers, in great detail, a single topic, of considerable theoretical interest and great practical importance. . . His command of the history, literature, theory and practice of emulsion polymerization, and its importance in the polymerization of vinyl acetate and related acrylic comonomers is remarkable and well set out in this book. . . The whole book is well referenced, and is recommended to any laboratory concerned with the production, examination or application of vinyl acetate-based emulsion polymers."
-CA Finch
"The authors intent was to provide "an introductory and clear text" about polyvinyl acetate-based latices and some of the problems involved in their production."
