Abstract:
Polyolefin compositions made from or containing:(A) about 5 to about 35% by weight of a propylene-based polymer containing about 90% by weight or more of propylene units and containing about 10% by weight or less of a fraction soluble in xylene at 25° C. (XSA);(B) about 25 to about 50% by weight, of a copolymer of ethylene and a C3-C8 alpha-olefin containing from about 0.1% to about 15% by weight of alpha-olefin units and containing about 75% by weight or less of a fraction soluble in xylene at 25° C. (XSB); and(C) about 30 to about 60% by weight, of a copolymer of ethylene and propylene containing from about 45% to about 75% by weight of ethylene units and containing from about 55% to about 95% by weight, of a fraction soluble in xylene at 25° C. (XSC).
