Title (EN) UNSATURATED $g(a)-OLEFIN COPOLYMERS AND METHOD FOR PREPARATION THEREOF
(FR) COPOLYMERES INSATURES D'$g(a)-OLEFINE ET PROCEDE DE PREPARATION DE CES DERNIERS
Abstract:
(EN) Disclosed are unsaturated $g(a)-olefin/$g(a),$g(v)-diene copolymers, and a method of preparation thereof. The copolymers are generally crystalline, free of gel and cross-links, and contain unsaturated side chains and long chain branching. The copolymers contain up to 5 mole percent diene incorporated therein, and may be prepared by copolymerization using a solid-phase, insoluble coordination catalyst, without a solvent, and below the crystalline melting point of the copolymer.
(FR) L'invention concerne des copolymères insaturés d'$g(a)-oléfine/$g(a),$g(v)-diène, et un procédé de préparation de ces derniers. Les copolymères sont globalement cristallins, exempts de gel et de réticulations, et ils contiennent des chaînes latérales insaturées et une ramification à longues chaînes insaturées. Les copolymères renferment jusqu'à 5 moles pour cent de diène incorporé et on peut les préparer par copolymérisation en utilisant un catalyseur de coordination insoluble, à phase solide, sans solvant, et à une température inférieure au point de fusion cristallin du copolymère.
