Patent ID: 7700688

Claim:
An elastomeric polymer blend composition comprising: A) from 65 to 92 parts by weight of at least one elastomeric monovinylidene aromatic-conjugated diene block copolymer, having a monovinylidene aromatic content of less than 50 weight percent based on the total weight of the elastomeric copolymer, and a weight average molecular weight of from 50,000 to 400,000; B) from 8 to 35 parts by weight of at least one thermoplastic monovinylidene aromatic-conjugated diene block copolymer, having a monovinylidene aromatic content of 60 weight percent or more based on the total weight of the thermoplastic copolymer, and a weight average molecular weight from 50,000 to 300,000; and C) from 0 to 30 parts by weight of an extender oil, based on the total weight of A, B and C, wherein the elastomeric polymer blend composition does not contain an amount of any polymer other than A and B greater than 5 weight percent of the blend, and wherein a plaque comprised of the elastomeric polymer blend composition has a percent haze of less than 50 percent and a percent transparency of greater than 75 percent in accordance with ASTM Method D 1003-92.
