ALUMINOXANATE SALT COMPOSITIONS HAVING IMPROVED STABILITY IN AROMATIC AND ALIPHATIC SOLVENTS

摘要

The present invention provides soluble aluminoxanate salt compositions, methods for preparing soluble aluminoxanate salt compositions, catalyst compositions comprising soluble aluminoxanate salt compositions, and methods for polymerizing olefins using catalyst compositions comprising soluble aluminoxanate salt compositions. Aluminoxanate salt compositions of the present invention are soluble in aromatic and aliphatic solvents and have improved solution stability and superior activator efficiency as compared to conventional aluminoxanes or modified aluminoxanes.
