Emulsion Polymerization Of Vinyl Acetate Monomer

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.

Emulsion polymerization of vinyl acetate monomer.

Vinyl monomers 1 4 like methyl acrylate ma ethyl acrylate ea ethyl hexyl acrylate. This is the case of the emulsion polymerization of vinyl acetate where the desired product is the homopolymer pva and the most important operating parameter to optimize and scale up the process is the monomer dosing time t dos. It is also used for the production of various copolymers like acrylonitrile butadiene styrene abs. By this reaction sequence the hydroxyethyl cellulose becomes chemically bonded onto the formed polymer.

Emulsion polymerization requires free radical polymerizable monomers which form the structure of the polymer. Vinyl acrylics vinyl acetate ethylene vae polyurethanes polyesters melamine. Emulsion polymerization of the monomers. Poly vinyl acetate latex b.

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. 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 acetate emulsion polymerization and copolymerization with acrylic monomers provides a collection and logical organization of the. There are many different types of emulsion polymerizations depending on.

Poly vinyl acetate latex c. 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. Rai2 1assistant professor. 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.

Kinetics of the emulsion polymerization of vinyl acetate. Acetate monomer previous to its use in the polymerization process. An emulsion polymerization system with uniform continuous addition of vinyl acetate monomer pluronic f68 surfactant and persulfate initiator has been examined with variation of the surfactant concentration over a tenfold range. Synthesis and characterization of emulsion polymerization of acrylate monomers sweta shukla1 and j.
