Title (EN) PROCESS FOR THE POLYMERIZATION OF ALPHA OLEFINS
(FR) PROCEDE DE POLYMERISATION D'ALPHA-OLEFINES
Abstract: front page image
(EN)A process for preparing 1-butene polymers, comprising polymerizing 1-butene or copolymerizing 1-butene with ethylene, propylene or an alpha-olefin of formula CHT2=CHT wherein T is a C3-C10 alkyl group, in the presence of a catalyst system obtainable by contacting: A) a metallocene compound belonging to formula (I): wherein M is zirconium titanium or hafnium; X, equal to or different from each other, is a hydrogen atom, a halogen atom, a a hydrocarbon radical, optionally containing heteroatoms; R4, R5, R6, R7, R8, R9, R10, R11, R12 and R13are hydrogen atoms, or C1-C4O hydrocarbon radicals optionally containing heteroatoms; R1, R2 and R3, are linear or branched, C1-C2o-alkyl radicals, optionally containing heteroatoms; B) a Jumoxane or a compound capable of forming an alkyl metallocene cation; and optionally C) organo aluminum compound.
(FR)Procédé d'élaboration de polymères de 1-butène : polymérisation de 1-butène ou copolymérisation de 1-butène avec éthylène, propylène ou une alpha-oléfine de formule CHT2=CHT sachant que T est un groupe C3-C10 alkyle, en présence de système catalyseur pouvant être établi par contact entre : A) composé métallocène de formule (I): sachant que M est zirconium, titane ou hafnium; X, égal ou différent, est atome d'hydrogène, atome halogène radical hydrocarbure, contenant éventuellement des hétéroatomes; R4, R5, R6, R7, R8, R9, R10, R11, R12 et R13 sont des atomes d'hydrogène ou des radicaux hydrocarbure C1-C4O contenant éventuellement des hétéroatomes; R1, R2 et R3, sont des radicaux C1-C2o-alkyle linéaires ou ramifiés, contenant éventuellement des hétéroatomes; B) un composé jumoxane ou un composé capable de former un cation métallocène alkyle; et éventuellement C) un composé organo aluminium.
