Cocatalyst effects in Hf-catalysed olefin polymerization: taking well-defined Al–alkyl borate salts into account

Abstract

Hafnium catalysts for olefin polymerization are often very sensitive to the nature of cocatalyst, especially if it contains “free” aluminum trialkyls. Herein, cocatalyst effects in Hf-catalyzed propene polymerization are examined...
