HYDROGENATED STYRENIC BLOCK COPOLYMERS BLENDS WITH POLYPROPYLENE

摘要

The present invention comprises a molding composition comprising at least about 70 % wt. polypropylene or polypropylene random copolymer; up to about 30 wt. % of a block copolymer composition comprising at least one selectively hydrogenated block copolymer which substantially matches the index of refraction of the polypropylene or polypropylene random copolymer, and up to about 0.70 % by wt. of a clarifying agent, wherein the weight % of the total blend is 100%. The present invention also may be a molded article produced from the molding composition. A molded article formed from such a composition at a thickness of 0.125 inches will have a haze of less than about 50 % and an instrumented impact toughness of at least 100 inch-lbs at -20°C to -30°C.
