(EN) REPROCESSABLE COMPOSITIONS
(FR) COMPOSITIONS POUVANT ÊTRE RETRAITÉES
Abstract
(EN) The present disclosure provides compositions comprising: (a) a copolymer prepared by a method comprising polymerizing in the presence of a metathesis catalyst: i) a first monomer, wherein each instance of the first monomer is independently of the formula (A) or salt thereof; ii) a second monomer, wherein each instance of the second monomer is independently of the formula (B), (B1), (B2), or a salt thereof; iii) optionally a third monomer, wherein the third monomer is different from the first monomer and the second monomer; and iv) optionally a reprocessing catalyst; and ( b) optionally the reprocessing catalyst; wherein the reprocessing catalyst is a Bronsted acid, Lewis acid, Bronsted base, Lewis base, or a salt thereof; provided that the composition comprises at least one of the reprocessing catalyst of iv) and the reprocessing catalyst of ( b). The compositions may be reprocessed (e.g., remolded) under elevated temperature and/or elevated pressure.
(FR) La présente divulgation concerne des compositions comprenant : (a) un copolymère préparé par un procédé consistant à polymériser en présence d’un catalyseur de métathèse : i) un premier monomère, chaque apparition du premier monomère s'effectuant indépendamment de la formule (A) ou de son sel ; ii) un second monomère, chaque apparition du second monomère s'effectuant indépendamment de la formule (B), (B1), (B2), ou de son sel ; iii) éventuellement un troisième monomère, le troisième monomère étant différent du premier monomère et du second monomère ; et iv) éventuellement un catalyseur de retraitement ; et (b) éventuellement le catalyseur de retraitement ; le catalyseur de retraitement étant un acide de Brönsted, un acide de Lewis, une base de Brönsted, une base de Lewis, ou son sel ; à condition que la composition comprenne au moins le catalyseur de retraitement de iv) et/ou le catalyseur de retraitement de (b). Les compositions peuvent être retraitées (par exemple, remoulées) sous température élevée et/ou pression élevée.
