CA 2338767
There is provided a catalyst containing a transition metal precursor having the formula (C5R15)TiY3, (wherein each y is independently selected from the group consisting of a C1-C20 alkoxide, a C1-C20 amide, a C1-C20 carboxylate and a C1-C20 carbomate) an alcohol or carboxylic acid, an aluminoxane, and optionally a substituted bulky phenol and/or a support or spray drying material. There is also provided a polymerization process employing the catalyst composition, a polymer produced using the catalyst, and a cable produced therefrom.
L'invention concerne un catalyseur contenant un précurseur de métal de transition représenté par la formule (C¿5?R?1¿¿5?)TiY¿3?, dans laquelle chaque y est indépendamment choisi dans le groupe constitué d'un alcoxyde C¿1?-C¿20?, d'un amide C¿1?-C¿20?, d'un carboxylate C¿1?-C¿20? et d'un carbamate C¿1?-C¿20?. Ce catalyseur comprend un alcool ou de l'acide carboxylique, un aluminoxane et éventuellement un phénol volumineux substitué et/ou un support ou matière de séchage par pulvérisation. L'invention concerne également un procédé de polymérisation utilisant la composition de catalyse, un polymère produit au moyen dudit catalyseur et un câble produit à partir dudit polymère.
