摘要： The present invention relates to articles prepared from novel anionic block copolymers of mono alkenyl arenes and conjugated dienes, and to blends of such block copolymers with other polymers. The block copolymers are selectively hydrogenated and have the structure C-A-B2-A-C or (C-A-B)nX, where the molecular weight of B2 is twice that of B, n is an integer between 2 and about 30, X is the residue of a coupling agent, and wherein prior to hydrogenation each A block is a mono alkenyl arene homopolymer block, each B block is a polymer block of at least one conjugated diene and each C block is a polymer block of (i) ethylene, (ii) alpha olefins of 3 to 10 carbon atoms; or (iii) monomers of 1,3-butadiene having a vinyl content less than 10 mol percent prior to hydrogenation. The block copolymer may be blended with at least one other polymer selected from the group consisting of olefin polymers, styrene polymers and amorphous resins.
