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 59.3 parts vinyl acetate there is used a 70:30 mixture of vinyl acetate and ethyl acrylate and the post-heating time at 85° C. is three hours. The resulting dispersion contains 50.8% solids and has a particle size of 0.44 micron. The polymer has a reduced specific viscosity of 1.24 which corresponds to a molecular weight above 100,000 and has a second order transition temperature of 6° C.
