Title (EN) NEW HOMOGENEOUS OLEFIN POLYMERIZATION CATALYST COMPOSITION
(FR) NOUVELLE COMPOSITION HOMOGENE DE CATALYSEUR DE POLYMERISATION DES OLEFINES
Abstract:
(EN) Homogeneous olefin polymerization catalyst compositions prepared by contacting a) a metallocene of the general formula (1): (CpYq)mMXnZo, wherein Cp is one of a mono- or polysubstituted, fused or non-fused, homo- (= iso-) or heterocyclic cyclopentadienyl ligand, Y is a substituent at the cyclopentadienyl ring and is one of an -OR, -SR, -NR2, -C(H or R)=, or -PR2 radical, M is a transition metal of Group 4 of the Periodic Table and bound to the ligand or ligands Cp in at least an $g(h)5 bonding mode; X is bound to M and is one of a hydrogen, a halogen, a C1-C8 hydrocarbyl group, a C1-C8 hydrocarbylheteroatom (O, S, N, P) group or a tri-C1-C8 hydrocarbyl silyl group or two X form together with M a C4-C20 metallocyclic ring structure; Z is a bridge atom or group between two Cp ligands or between one Cp ligand and the transition metal M; q is 0-5; m is 1 or 2; m.q $m(G) 1; o is 0 or 1; and n is 4-m-o, except when there is a bridge Z between two Cp ligands, in which case n is 4-m, and b) an aluminoxane of one of formulas (2), (OAlR')p (2 general), wherein each R' is the same or different and is a C2-C10 alkyl group; and p is an integer between 1 and 40.
(FR) L'invention concerne des compositions homogènes de catalyseurs de polymérisation des oléfines, que l'on prépare en mettant en contact a) un métallocène de formule générale (1) (CpYq)mMXnZo, dans laquelle Cp est un ligand cyclopentadiényle mono ou polysubstitué, condensé ou non condensé, homo (= iso) ou hétérocyclique, Y est un substituant au niveau du noyau cyclopentadiényle et un radical OR, SR, NR2, C(H ou R)= ou PR2; M est un métal de transition du groupe 4 de la classification périodique lié au ligand ou aux ligands Cp au moins sur un mode de liaison $g(h)5; X est lié à M et est hydrogène, halogène, un groupe hydrocarbyle C1-C8, un groupe hydrocarbyle C1-C8 renfermant un hétéroatome (O, S, N, P) ou un groupe tri-hydrocarbylsilyle C1-C8, ou bien deux X forment avec M une structure noyau métallocyclique C4-C20; Z est un atome ou un groupe de pontage entre deux ligands Cp ou bien entre un ligand Cp et le métal de transition M; q est compris entre 0 et 5; m est 1 ou 2; m.q est $m(G) 1; o est 0 ou 1; et n est 4-m-o, sauf quand il y a un pont Z entre deux ligands Cp, cas dans lequel n est 4-m; et b) un aluminoxane de formule générale (2) (OAlR')p (2 général), dans laquelle chaque R', identique ou différent, est un groupe alkyle C2-C10; et p est un entier compris entre 1 et 40.
