ABSTRACT:
Non-conjugated dienes are reacted with phenolic compounds in the presence of a Friedel-Crafts catalyst to produce poly(phenol/diene) copolymer resin having repeating alternate phenol and diene units, a number average molecular weight of 600-5000 and a glass transition temperature of 100.degree.-220.degree.C. The resin, and its partially or fully hydrogenated counterpart, can be blended with various rubbery polymers to provide adhesive compositions having improved adhesive tack.
