(FR) COMPOSITIONS DE COPOLYMÈRE DE POLYPROPYLÈNE DURCI PAR ÉCROUISSAGE
Abstract
(EN)
The present disclosure relates to compositions including copolymers, and methods for making compositions. In an embodiment, a composition includes the product of a copolymer comprising at least 50 mol% propylene and at least 1 wt% of at least one of ethylene or a C4 to C10 α-olefm, based on the total weight of the copolymer; and an organic peroxide. The copolymer has MwMALLs/MnMALLS of from 1 to 5. In an embodiment, a process to form a composition includes introducing a copolymer with an organic peroxide, the copolymer comprising at least 50 mol% propylene and at least 1 wt% of at least one of ethylene or a C4 to C10 α-olefm, based on the total weight of the copolymer; and obtaining a composition comprising a product of the copolymer and the organic peroxide. The copolymer has MwMALLs/MnMALLS of from 1 to 5.

La présente invention concerne des compositions comprenant des copolymères et des procédés de fabrication des compositions. Dans un mode de réalisation, une composition comprend le produit d'un copolymère comprenant au moins 50 % en moles de propylène et au moins 1 % en poids d'au moins l'un de l'éthylène ou d'une α-oléfine en C4 à C10, sur la base du poids total du copolymère ; et un peroxyde organique. Le copolymère présente un rapport MwMALLs/MnMALLS de 1 à 5. Dans un mode de réalisation, l'invention concerne un procédé de formation d'une composition comprenant l'introduction d'un peroxyde organique dans un copolymère, le copolymère comprenant au moins 50 % en moles de propylène et au moins 1 % en poids d'au moins l'un de l'éthylène ou d'une α-oléfine en C4 à C10, sur la base du poids total du copolymère ; et l'obtention d'une composition comprenant un produit du copolymère et du peroxyde organique. Le copolymère présente un rapport MwMALLs/MnMALLS de 1 à 5.
