CA 2663342

Compositions useful for activating catalysts for olefin polymerization are provided. The compositions are derived from at least carrier having at least two hydrogen bonded hydroxyl groups, organoaluminum compound, Lewis base, and Bronsted acid, wherein the Lewis base and the Bronsted acid form at least one ionic Bronsted acid.

La présente invention concerne des compositions convenant à l'activation de catalyseurs pour la polymérisation d'oléfines. Ces compositions sont dérivées d'au moins un vecteur comportant au moins deux groupes hydroxyle, d'un composé d'organoaluminium, d'une base de Lewis, d'un acide de Brönsted, la base de Lewis et la base de Brönsted formant au moins un acide de Brönsted ionique.
