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: an organoalurninum compound, a carrier, an oxygen source, and, optionally, a Lewis base.
