Title
(EN) ETHYLENE/α-OLEFIN INTERPOLYMERS CONTAINING LOW CRYSTALLINITY HARD BLOCKS
(FR) INTERPOLYMÈRES ÉTHYLÈNE/α-OLÉFINE CONTENANT DES BLOCS DURS DE FAIBLE CRISTALLINITÉ
Abstract
(EN)
The invention is related to an ethylene/α-olefin interpolymer having at least a hard segment and at least a soft segment. The soft segment contains a higher amount of comonomers than the hard segment. The hard segment has low crystallinity. The copolymer has a number of unique characteristics disclosed herein.ethylene/α-olefin interpolymers containing low crystallinity hard blocks
(FR)
L'invention concerne un interpolymère éthylène/α-oléfine comprenant au moins un segment dur et au moins un segment mou. Le segment mou contient une quantité supérieure de comonomères par rapport au segment dur. Le segment dur présente une faible cristallinité. Le copolymère présente un certain nombre de caractéristiques spécifiques décrites ici.
