Compositions useful for activating catalysts for olefin polymerization, and methods for making same, are provided. Such compositions can be derived from at least: a) an intermediate composition derived from at least an organoaluminium compound, a carrier, and an oxygen source; and b) R2 2 AIY, wherein each R2 independently comprises a hydrocarbyl group having from 1 to 20 carbons, and Y comprises a halide radical, a pseudo halide radical, an alkoxide radical, an aryloxide radical, an alkyl substituted amide radical, an aryl substituted amide radical, a siloxy radical, a boronoxy radical, a diaryl boronoxy radical, or a halogenated diaryl boronoxy radical.
L'invention porte sur des compositions utiles pour activer des catalyseurs pour la polymérisation des oléfines, et sur des procédés pour les fabriquer. De telles compositions peuvent être issues d'au moins a) une composition intermédiaire dérivée d'au moins un composé organoaluminium, d'un support et d'une source d'oxygène; et b) de R2 2 AIY, R2 contenant indépendamment un groupe hydrocarbyl portant 1 à 20 atomes de carbone, Y comportant un radical halide, un radical pseudo halide, un radical alkoxyde, un radical aryloxyde, un radical amide à substitution amide, un radical amide à substitution aryle, un radical siloxy, un radical boronoxy, un radical diaryle boronoxy ou un radical diaryle boronoxy halogéné.
