Abstract
(EN)
The present invention relates to a thermoplastic elastomer composition which comprises a branched olefin copolymer comprising: a main chain of an ethylene/±-olefin copolymer; and a side chain derived from a crystalline propylene polymer containing a vinyl group at one end, wherein the content of ±-olefin in the main chain is 70 mol% or less, the composition has an elongation at break of 500% or higher, and has an elastic recovery rate of 70% or more when recovering from an extension to 300% elongation, and a process for manufacturing the same.

(FR)
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.
