Title (EN) PROCESS FOR THE POLYMERIZATION OF $g(a)-OLEFINS
(FR) PROCEDE DE POLYMERISATION D'$g(a)-OLEFINES
Abstract:
(EN) Process for the polymerization of $g(a)-olefins under polymerization conditions in the presence of a transition metal complex and an activator, in which the transition metal complex is a complex according to the formula (I): COTxMLyAz where: M = a transition metal from groups 3-6 of the Periodic System of the Elements COT = a cyclooctatetraene ligand (C8R'8) and R' = a substituent; L = an anionic pi-bound ligand; A= a neutral ligand; y = the valency of M-(2*x); x = a number larger than or equal to 1/2, divisible by 1/2; and z = an integer larger than or equal to 0; and wherein the activator is a neutral Lewis acid or an ion complex.
(FR) Procédé de polymérisation d'$g(a)-oléfines dans des conditions de polymérisation en présence d'un complexe de métal de transition et d'un activateur, ce complexe de métal de transition étant représenté par la formule I: COTxMLyAz (I) dans laquelle: M représente un métal de transition des groupes 3-6 du système périodique des éléments; COT représente un ligand de cyclooctatétraène (C8R'8) et R' représente un substituant; L représente un ligand anionique à liaison pi; A représente un ligand neutre; y est la valence de M-(2*x); x est un nombre supérieur ou égal à 1/2 divisible par 1/2 et z est un entier supérieur ou égal à 0; l'activateur étant un acide de Lewis neutre ou un complexe d'ions.
