Abstract
A thermoplastic elastomer composition comprising a block copolymer having at least two resinous endblocks and a high 1,2-addition butadiene midblock, a paraffin oil and a crystalline polyolefin. The composition exhibits greater softness, better processability and better elastic properties as compared with similar compositions made with normal amounts of a 1,2-addition. Compositions are useful for utilities such as overmolding into hard substrates, grips, medical tubing and miscellaneous rubbery articles.
