manufacturing process for poly vinyl acetate in wikipedia

The process involves the reaction of monomer molecules of vinyl acetate by submerging them into water. This results in the formation of a polyvinyl acetate emulsion that is milky white in color. The emulsion fluid can then instantly be processed as a polyvinyl acetate polymer in products comprising the PVAc as a constituent element.

The catalyst generally used is a mixture of copper(ll) and potassium chlorides, deposited on alumina. As the reaction is highly exothermic, the reactor vessel is cooled to give the optimum reaction temperature and to reduce unwanted by-product formation of, for example, chloroethane and 1,1,1,2-tetrachloroethane. 95% conversion of ethene to 1,2-dichloroethane is obtained.
