Vinyl Acetate → Ethenyl acetate--ethyl prop-2-enoate (1/1)

Participants

Reaction Steps

Finely divided vinyl acetate-ethyl acrylate copolymer is prepared exactly as described in Example 1 except that in place of vinyl acetate there is used a 60:40 mixture of vinyl acetate and ethyl acrylate. The postheating time is extended to 2-1/2 hours at 80° C. followed by distillation to remove 66.5 parts of a mixture of unreacted monomer and solvent. The resulting dispersion contains 53.6% solids and has a particle size of 0.43 micron. The polymer has a reduced specific viscosity of 1.24 which indicates a molecular weight above 100,000 and has a glass transition temperature of 0° C.
