COMPOSITIONS COMPRISING A CO-POLYMER OF AN AROMATIC HYDROCARBON AND A CONJUGATED DIENE HYDROCARBON,RUBBER EXTENDING OIL AND A POLYMER OF AROMATIC HYDROCARBON

摘要

Block copolymer compositions having improved adhesion to porous substrates are prepared by employing an anionic polyarene as a component instead of a free radical polymerized polyarene. Also disclosed is a process for simultaneously preparing the block copolymer and anionic polyarene.
