    • A polymeric laminate comprising (A) a substrate, and (B) a slip layer covering at least a portion of said substrate, where the slip layer consists essentially of (i) a polyethylene blend, where said blend includes (a) from about 3 to about 97 percent by weight, based upon the total weight of said blend, of a first polyethylene resin having a weight average molecular weight from 110,000 to about 140,000 and a polydispersity of less than about 12, (b) from about 3 to about 97 percent by weight, based upon the total weight of said blend, of a second polyethylene resin having a weight average molecular weight from 50,000 up to 109,999 and a polydispersity of less than about 12, and (c) from about 0 to about 40 percent by weight, based upon the total weight of said blend, of a third polyethylene resin having a weight average molecular weight from about 20,000 up to 49,999 and polydispersity of less than about 12, with the proviso that said blend includes at least 60 percent, based upon the total weight of said blend, of said first polyethylene and said second polyethylene combined, (ii) from about 2.5 to about 15 parts by weight, per 100 parts by weight of said polyethylene blend, of a propylene polymer or copolymer having propylene units deriving from propylene monomer, and (iii) from about 4.5 to about 20 parts by weight, per 100 parts by weight of said polyethylene blend, of a dynamically vulcanized rubber.
    • 一种聚合物层压体,其包含(A)基材和(B)覆盖所述基材的至少一部分的滑移层,其中所述滑移层基本上由(i)聚乙烯共混物组成,其中所述共混物包含(a)约3 至约97重量%,基于所述共混物的总重量,第一聚乙烯树脂的重均分子量为110,000至约140,000,多分散度小于约12,(b)约3至约97 重量百分比,基于所述共混物的总重量,重均分子量为50,000至109,999的第二聚乙烯树脂和小于约12的多分散性,和(c)约0至约40%的 基于所述共混物的总重量,重均分子量为约20,000至49,999的第三聚乙烯树脂和小于约12的多分散性,条件是所述共混物包含至少60%,基于 的 所述第一聚乙烯和所述第二聚乙烯组合的所述共混物的总重量,(ii)每100重量份所述聚乙烯共混物约2.5至约15重量份的具有丙烯单元的丙烯聚合物或共聚物,衍生自 丙烯单体,和(iii)每100重量份所述聚乙烯共混物约4.5至约20重量份的动态硫化橡胶。
