Pvac is also combined with other polymers to obtain composites blends and copolymers for instance. Poly vinyl chloride co vinyl acetate co vinyl alcohol 1 product result match criteria. Poly vinyl acetate pvac is a thermoplastic and amorphous polymer that is employed in a large variety of industrial applications including. Applications edit as an emulsion in water pvac emulsions are used as adhesives for porous materials particularly for wood paper and cloth and as a consolidant for porous building stone in.

Polyvinyl acetate is prepared by the polymerization of vinyl acetate monomer free radical vinyl polymerization of the monomer vinyl acetate. And the raft agent diphenylcarbamodithioate which will allow for additional polymerization to generate a diblock copolymer. The polymerization reaction proceeded as a living polymerization and was remarkably rapid compared with approaches that use thermally initiated processes with a very short induction period. Controlled living radical polymerization of vinyl acetate was achieved by a degenerative transfer process using alkyl iodides as transfer agents.
