Emulsion polymerization of the monomers.

Emulsion polymerization of vinyl acetate monomer.

Vinyl acetate emulsion polymerization and copolymerization with acrylic monomers provides a collection and logical organization of the. Vinyl acrylics vinyl acetate ethylene vae polyurethanes polyesters melamine. Poly vinyl acetate latex c. The major monomers used in emulsion polymerization include butadiene styrene acrylonitrile acrylate ester and methacrylate ester monomers vinyl acetate acrylic acid and methacrylic acid and vinyl chloride.

Vinyl monomers 1 4 like methyl acrylate ma ethyl acrylate ea ethyl hexyl acrylate. Therefore the study of vinyl acetate bulk polymerization is of great interest from a process safety point of view even if it is not a commercial wide spread process. Emulsion polymerization is one of the most important methods for the polymerization of a large number of monomers like vinyl acetate vinyl chloride chloroprene acrylamide acrylates and methacrylates. Persulfate initiated vinyl acetate vinyl versatate copolymer latex.

It is also used for the production of various copolymers like acrylonitrile butadiene styrene abs. I the ty pe of dispersion oil in water or water in oil. 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. Acetate monomer previous to its use in the polymerization process.

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.
