ALUMINOXANE CATALYST ACTIVATORS DERIVED FROM DIALKYLALUMINUM CATION PRECURSOR AGENTS, PROCESSES FOR MAKING SAME, AND USE THEREOF IN CATALYSTS AND POLYMERIZATION OF OLEFINS.

摘要

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) Rsup2/sup 2 AIY, wherein each Rsup2/sup 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.
