Abstract
A pressure sensitive adhesive composition comprising a polymer of an acrylate ester and/or vinyl ester, an olefinically unsaturated carboxylic acid comonomer, and a polyolefinically unsaturated copolymerizable monomer for enhancing cohesive strength of the interpolymer, the polymer being formed by an aqueous emulsion polymerization process in the presence of a stabilizer system comprising a hydroxypropyl methyl cellulose and an ethoxylated acetylenic tertiary diol.
