Title (EN) COMPOSITIONS OF OLEFIN BLOCK COPOLYMERS AND PROPYLENE-BASED ELASTOMERS
(FR) COMPOSITIONS DE COPOLYMÈRES SÉQUENCÉS D'OLÉFINE ET D'ÉLASTOMÈRES À BASE DE PROPYLÈNE
Abstract: front page image
(EN)Polymer blends comprising at least one olefin block copolymer such as poly(ethylene-b-ethylene/propylene-b-ethylene), and at least one propylene-based elastomer such as a propylene-ethylene random copolymer, such blends useful in elastic hygiene articles. The blends have improved permanent set compared to the propylene-based elastomer alone.
(FR)L'invention concerne des mélanges de polymères comprenant au moins un copolymère séquencé d'oléfine tel que le poly(éthylène-b-éthylène/propylène-b-éthylène), et au moins un élastomère à base de propylène tel qu'un copolymère aléatoire de propylène-éthylène, de tels mélanges utiles dans des articles d'hygiène élastiques. Les mélanges ont une déformation permanente améliorée par rapport à l'élastomère à base de propylène seul.
