    摘要: Thermoplastic polyolefin compositions useful for soft touch applications comprise, in weight percent based upon the weight of components A and B, about: A. 99 to about 1 percent of at least one polypropylene homopolymer or copolymer; and B. 99 to about 1 percent of at least one homogeneously branched ethylene/&agr;-olefin copolymer in which the &agr;-olefin contains at least 4 carbon atoms and the homogeneously branched copolymer has a crystallinity of less than about 3 percent.
