ABSTRACT:
This invention relates to an improved pressure sensitive adhesive comprising a polymer system which has excellent tack, peel and shear adhesion strengths. The improvement resides in the polymer, with the polymer system being formed by emulsion polymerizing an unsaturated ester, an unsaturated carboxylic acid and a polyfunctional monomer in the presence of a stabilizer system comprising an ethoxylated acetylenic tertiary glycol and polyvinyl alcohol.
