Abstract[English]
A method may include processing a crosslinked polymer and a catalyst to form a vitrimer during a melt processing operation, the crosslinked polymer comprising at least one monomer selected from a vinyl ester, a C2-C12 olefin, and combinations thereof. A method may include mixing a crosslinked polymer, a catalyst, and a non- crosslinked polymer at a temperature higher than a processing temperature of the non- crosslinked polymer to form a polymer composition; wherein each of the crosslinked polymer and the non-crosslinked polymer comprise at least one monomer selected from a vinyl ester, a C2-C12 olefin, and combinations thereof, and wherein the crosslinked polymer is present in an amount that is at least 15 wt%, relative to the combined total of crosslinked polymer and non-crosslinked polymer.[French]
Un procédé selon la présente invention peut comprendre le traitement d'un polymère réticulé et d'un catalyseur pour former un vitrimère pendant une opération de traitement à l'état fondu, le polymère réticulé comprenant au moins un monomère choisi parmi un ester de vinyle, une oléfine en C2 à C12 et des combinaisons de ceux-ci. Un procédé peut comprendre le mélange d'un polymère réticulé, d'un catalyseur et d'un polymère non réticulé à une température supérieure à une température de traitement du polymère non réticulé pour former une composition polymère ; le polymère réticulé et le polymère non réticulé comprenant chacun au moins un monomère choisi parmi un ester de vinyle, une oléfine en C2 à C12 et des combinaisons de ceux-ci, et le polymère réticulé étant présent en une quantité qui est d'au moins 15 % en poids, par rapport au total combiné de polymère réticulé et de polymère non réticulé.
