Abstract
(EN)
The present invention relates to a thermoplastic elastomer composition comprising a branched-structure olefin-based copolymer including an ethylene/α-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 α-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.

La présente invention concerne une composition élastomère thermoplastique comprenant un copolymère à base d'oléfine à structure ramifiée comprenant une chaîne principale de copolymère d'éthylène/α-oléfine et une chaîne latérale dérivée d'un polymère de propylène cristallin contenant un groupe vinyle à une extrémité. Selon l'invention, la chaîne principale contient l'α-oléfine en une quantité inférieure ou égale à 70 % en moles, et la composition présente un allongement à la rupture supérieur ou égal à 500 % et une recouvrance élastique supérieure ou égale à 70 % lors d'une recouvrance à un allongement de 300 %; la présente invention concerne également un procédé de production de celle-ci.
