ABSTRACT:
A modified aluminoxane is disclosed. Aluminoxane compounds are modified with glycol ethers or polyethers. The modified aluminoxanes are effective activators for single-site catalysts. Catalyst activated with the modified aluminoxane produces polyolefin with increased melt flow index, broadened molecular weight distribution, and improved thermal processability.
