Vinyl Acetate → HCID 23051942, compound

Participants

Reaction Steps

Finely divided vinyl acetate-ethyl acetate copolymer is prepared exactly as described in Example 1 except that in place of the vinyl acetate there is used an 85:15 mixture of vinyl acetate and ethyl acrylate. The resulting dispersion contains 51.4% solids, and has a particle size of 0.45 micron. The polymer has a reduced specific viscosity of 1.32 determined in chloroform solution at 25° C., which indicates a molecular weight above 100,000, and has a second order transition temperature of 19° C.
