Title:
PROCESS FOR FORMING SOLID PRESSURE SENSITIVE ADHESIVE POLYMER MICROSPHERES
Document Type and Number:
WIPO Patent Application WO2003042261
Kind Code:
A3
Abstract:
In forming pressure sensitive adhesive microspheres by copolymerizing a nonionic monomer of an alkyl acrylate or alkyl methacrylate ester of a non-tertiary alcohol and an acid monomer copolymerizable with said non-ionic monomer, an electrolyte is present during the polymerization to promote formation of solid rather than hollow microspheres.
