Abstract

Process for preparing a non-linear block copolymer according to any of the preceding claims, which comprises polymerizing a vinyl substituted aromatic hydrocarbon in a liquid hydrocarbon as a diluent, in the presence of a monolithic hydrocarbon compound as catalyst, to form a non-elastomeric polymer block A Initial, continue the polymerization by adding a conjugated diene hydrocarbon to form an elastomeric polymer block B and attached to the initial non-elastomeric polymer block A, polymerize a vinyl substituted aromatic hydrocarbon, a conjugated diene hydrocarbon or a polar organic compound, such as vinylpyridine, methacrylonitrile, vinylquinoline, vinyl isoquinoline, a methacrylate or acrylate ester, separately, in a liquid hydrocarbon as a diluent, in the presence of a monolithic hydrocarbon compound as a catalyst, to form a polymeric D block, mix the solutions of the AB-Li poly block ero active and D-Li active polymer block, and coupling the active polymer blocks with a coupling agent that is at least trifunctional in terms of their coupling activity.
