Title
(EN) Thermoplastic elastomer composition and method for producing same
(ZH) 热塑性弹性体组合物及其制造方法
Abstract
(EN)
The present invention relates to a thermoplastic elastomer composition comprising a branched-structure olefin-based copolymer including an ethylene/alpha-olefin copolymer main chain and a side chain derived from a crystalline propylene polymer containing a vinyl group at one terminus, wherein the main chain contains the alpha-olefin in an amount of 70 mol% or less, and the composition exhibits an elongation at rupture of not less than 500% and exhibits an elastic recovery of not less than 70% upon recovery from 300% elongation; the present invention also relates to a method for producing the same.
