Popcorn-shaped polyethylene synthesised using highly active supported permethylindenyl metallocene catalyst systems

Abstract

Unsymmetrical permethylindenyl bent metallocene complexes have been synthesised and reacted with inorganic solid supports to afford catalysts for the slurry phase polymerisation of ethylene. Those supported on solid polymethylaluminoxane were both highly active catalysts and afforded polymers with a desirable, low aggregation, “popcorn” morphology.
