Title (EN) METALLOCENE-CATALYZED POLYALPHA-OLEFINS
(FR) POLY(ALPHA-OLÉFINES) OBTENUES PAR CATALYSE AVEC UN MÉTALLOCÈNE
Abstract:
(EN) Unsaturated and hydrogenated polyalpha-olefin products can be made with a high selectivity toward vinylidenes and tri-substituted vinylenes combined, a high selectivity toward vinylidenes, and a low selectivity toward 1,2-di-substituted vinylenes by using a catalyst system comprising a metallocene compound having the following structure in the polymerization reaction: In formula (F-MC), Rl and R4 are each independently a hydrogen or a C1-C30 hydrocarbyl group, R2 and R3 are each independently a C1-C50 hydrocarbyl group, R5, R6, R7 and R8 are each independently a hydrogen or a C1-C30 hydrocarbyl group, provided that R6 and R7 are not both hydrogen. The first Cp ring and the second Cp ring may be annelated but not simultaneously.
(FR) L'invention concerne des produits poly(alpha-oléfines) insaturées et hydrogénées qui peuvent être formés avec une sélectivité élevée vis-à-vis des vinylidènes et des vinylènes trisubstitués combinés, une sélectivité élevée vis-à-vis des vinylidènes, et une faible sélectivité vis-à-vis des vinylènes 1,2-disubstitués à l'aide, dans la réaction de polymérisation, d'un système catalyseur comprenant un composé métallocène ayant la structure (F-MC).
