The pigment binder PD is composed of a nucleus with softer monomer content and a shell with harder monomer content.

The method of emulsion polymerization was used to synthesize polyvinyl acetate resin by adding hard monomer_methyl methacrylate to modify it.

The effects of propdrtion of soft and hard monomer, the content of functional monomer and emulsifier on the viscosity, ball tack and hold tack, peeling strength of adhesives were discussed.
