Title
(EN) CATALYST COMPOSITION COMPRISING SHUTTLING AGENT FOR REGIO-IRREGULAR MULTI-BLOCK COPOLYMER FORMATION
(FR) COMPOSITION CATALYTIQUE COMPRENANT UN AGENT NAVETTE POUR LA FORMATION D'UN COPOLYMERE MULTIBLOCS A REGIONS IRREGULIERES
Abstract
(EN)
Copolymers, especially multi-block copolymer containing therein two or more segments or blocks, are prepared by polymerizing propylene, 4-methyl-1-pentene, or another C4-8 &agr;-olefin in the presence of a composition comprising the admixture or reaction product resulting from combining: (A) a first metal complex olefin polymerization catalyst, (B) a second metal complex olefin polymerization catalyst capable of preparing polymers having increased incidence of regio-irregular branching compared to the polymer prepared by catalyst (A) under equivalent polymerization conditions, and (C) a chain shuttling agent.
(FR)
Cette invention concerne des copolymères, en particulier ds copolymères multiblocs renfermant au moins deux segments ou blocs obtenus par polymérisation de propylène, de 4-méthyl-1-pentène, ou autre a-oléfine en C4-8 en présence d'une composition contenant l'adjuvant ou le produit de réaction issu de la combinaison de: (A) un premier catalyseur de polymérisation oléfinique à complexe métallique, (B) un second catalyseur de polymérisation oléfinique à complexe métallique capable de produire des polymères à incidence accrue de ramifications régio-irrégulières par rapport au polymère obtenu au moyen du catalyseur (A) dans des conditions de polymérisation équivalentes, et (C) un agent navette de chaîne.
