    摘要: A soft multicomponent compound comprising a styrenic block copolymer having good elastomeric properties, a paraffinic oil, a crystalline polyolefin and a metallocene polyolefin having a density from 0.86 to 0.91, a molecular weight distribution less than 3, and good distribution of ethylene and from 12% to 30% by weight of one or more .alpha.-olefin monomers having from 4 to 12 carbon atoms. The metallocene polyolefin partly replaces the styrenic block copolymer in conventional soft compounds and provides the desired softness at significantly lower oil contents, thus avoiding surface tackiness and oil extractability.
