    摘要: Disclosed is a novel tetrablock copolymer having the general configuration of A1-B1-A2-B2, where the A1 and A2 blocks are mono alkenyl arene and the B1 and B2 blocks are blocks of hydrogenated butadiene, having a 1,2-vinyl content of between 25% and 60%. The blocks have well defined molecular weight ranges, resulting in a polymer having a unique set of property advantages. Also disclosed are elastomeric compositions containing the linear hydrogenated block copolymer, a styrene polymer, an ethylene polymer and a tackifying resin. These elastomeric compositions have particular utility in injection molded parts and in extruded parts such as extruded films and fibers.
