The photoinduced polymerization of vinyl acetate vac proceeded very fast even at 40 c with a catalytic amount of mn 2 co 10 0 025 mol of vac or 5 0 mol of r i and completed within a few hours to give the polymers with controlled molecular weights up to 10 5.
The major industrial route involves the reaction of ethylene and acetic acid with oxygen in the presence of a palladium catalyst.
Polyvinyl acetate adhesives pvac polyvinyl acetate latex known as white latex is made of vinyl acetate monomer water dispersing agent polymerization starter and other auxiliary materials mixed together through emulsion polymerization.
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.
