Overview

This research reveals how methylaluminoxane-diphosphine systems enhance polymerization of ethylene and 1,3-butadiene.

Key Points

  • Polymerization using the DPPB/MAO system showed significantly higher activity than other systems.
  • The diphosphine catalyst resulted in the formation of cationic dialuminum species necessary for effective polymerization.
  • Cationic aluminum catalysts promote both ethylene and 1,3-butadiene polymerization through distinct mechanisms.
  • Polybutadiene with high cis-1,4 selectivity was achieved using the BIPHEP/MAO system for 1,3-butadiene.
