Patent ID: 7265180

Claim:
A thermoplastic molding composition consisting essentially of: (i) a copolymer having a number average molecular weight of 30 to 120 kg/mole and weight average molecular weight of 60 to 240 that is a product of polymerization of (A.1) at least one member selected from the group consisting of styrene, nucleus-substituted styrene, and methyl methacrylate and (A.2) at least one member selected from the group consisting of acrylonitrile, maleic anhydride, N-alkyl-substituted maleic imide and N-aryl-substituted maleic imide, and (ii) a styrene-butadiene-styrene (SBS) block copolymer having butadiene content of 20 to 30 percent relative to its weight, wherein the content of (A.2) in the copolymer is 19 to 27.5% relative to the weight of the copolymer; and wherein the composition has a haze value not greater than 15% and a transmittance greater than 87%.
