摘要
PROBLEM TO BE SOLVED: To provide a substantially transparent embrittlement-resistant composition, not requiring an expensive visbreaking step for imparting radiation resistance or homogeneous mixing of a mobilizer oil, and providing a flexible and substantially transparent product having a heat distortion temperature of ≥60°C by injection molding.;SOLUTION: The embrittlement-resistant polyolefin composition includes (a) at least 80% by weight, based on the total weight of the polyolefin composition, of a crystalline polymer comprising either a propylene homopolymer having an isotactic index greater than 90 or a random copolymer of propylene and either ethylene or 4-10C 1-olefins, and (b) an elastomeric copolymer of ethylene and either propylene or butene-1.;COPYRIGHT: (C)2007,JPO&INPIT
