摘要:
The present invention provides activator-supports containing alumina-silica compounds with high levels of alumina, and polymerization catalyst compositions employing these activator-supports. Methods for making these activator-supports based on alumina-silica and for using such compounds in catalyst compositions for the polymerization and copolymerization of olefins are also provided.
