ELASTOMERIC COMPOSITIONS COMPRISING VINYLAROMATIC BLOCK COPOLYMER, POLYPROPYLENE, PLASTOMER, AND LOW MOLECULAR WEIGHT POLYOLEFIN
摘要：
A composition comprising: (i) at least one low molecular weight polyolefin; (ii) at least one block copolymer obtainable by selectively hydrogenating a block copolymer having terminal polymeric blocks of a vinyl aromatic monomer and a mid-block prepared originally with an olefin and subsequently hydrogenated; (iii) at least one polypropylene; and (iv) at least one plastomer, wherein the plastomer is an ethylene based polymer having a density of 0.86 g/cc to about 0.910 g/cc or a propylene based polymer having a heat of fusion (Hf) of 70 J/g or less.
摘要（中）：

一种组合物，其包含：（i）至少一种低分子量聚烯烃; （ii）通过选择性氢化具有乙烯基芳族单体的末端聚合物嵌段和最初用烯烃制备的中间嵌段并随后氢化的嵌段共聚物获得的至少一种嵌段共聚物; （iii）至少一种聚丙烯; 和（iv）至少一种塑性体，其中塑性体是密度为0.86g / cc至约0.910g / cc的乙烯基聚合物或具有70J / g熔融热（Hf）的丙烯基聚合物或 减。
