ABSTRACT:
A highly branched copolymer particularly suitable for forming pressure sensitive adhesives prepared in the presence of specified amounts of tert-butylchloride. Conjugated diene monomers are copolymerized with monovinylaromatic monomers in the presence of an organolithium initiator and a suitable amount of tertiary butylchloride. The holding power of adhesives prepared thereby is greatly increased.
