PROCESS FOR FORMING SOLID PRESSURE SENSITIVE ADHESIVE POLYMER MICROSPHERES.

摘要

In forming pressure sensitive adhesive microspheres by copolymerizing a non -ionic monomer of an alkyl acrylate or alkyl methacrylate ester of a non-tertiary alcohol and an acid monomer copolymerizable with said non-ionic monomer, anelectrolyte is present during the polymerization to promote formation of solid rather than hollow microspheres.
