Abstract
Pressure-sensitive adhesives having improved cohesive strength are obtained by reacting an acrylic interpolymer containing an interpolymerized acrylic monomer containing an ethylenically unsaturated carboxylic acid anhydride with a metal alkoxide, chelated metal alkoxides such as chelated titanium esters being particularly preferred. Adhesives produced in this manner have improved cohesive strength on backings while maintaining good tack and adhesive properties.
