Abstract
Abstract There is provided a tackifier composition especially suited for use with natural rubber latex and formed from an olefin resin, preferably a polymerized terpene hydrocarbon resin condensed with an unsaturated carboxylic acid or anhydride, optionally partially esterified with a C 1 -C 30 alcohol or phenol, and neutralized with a base, preferably a volatile base such as an amine, and then dispersed in an aqueous medium. The tackifier when added to a latex forms compositions useful particularly as pressure sensitive adhesives.
