A compound useful as a catalyst activator corresponding to the formula: (A*+a)b(Z*J*j)-c d wherein: A* is a cation of charge +a, Z* is an anion group of from 1 to 50 atoms not counting hydrogen atoms, further containing two or more Lewis base sites; J* independently each occurrence is a Lewis acid coordinated to at least one Lewis base site of Z*, and optionally two or more such J* groups may be joined together in a moiety having multiple Lewis acidic functionality, j is a number from 2 to 12 and a, b, c, and j are integers from 1 to 3, with the proviso that a x b is equal to c x d.

L'invention concerne un composé pouvant être utilisé comme activateur de catalyseur, correspondant à la formule (A*<+a>)b(Z*J*j)<-c>d dans laquelle A* est un cation avec une charge +a, Z* est un groupe d'anions comportant entre 1 et 50 atomes, ne comptant pas d'atomes d'hydrogène, et contenant, en outre, deux ou plusieurs sites de base de Lewis; J*, indépendamment, est un acide de Lewis coordonné à au moins un site de base de Lewis de Z*, et éventuellement, deux ou plusieurs groupes J* peuvent être assemblés en une fraction comportant de multiples fonctionnalités d'acide de Lewis. J est un nombre compris entre 2 et 12 et a, b, c et d sont des nombres entiers compris entre 1 et 3 à condition que a x b soit égal à c x d.
