- Supported permethylindenyl titanium catalysts for the synthesis of disentangled ultra-high molecular weight polyethylene (: Dis UHMWPE)
-
Novel permethylindenyl-phenoxide (PHENI?) ansa-metallocene titanium complexes have been synthesised and immobilised on inorganic solid supports to afford highly effective catalysts for slurry-phase ethylene polymerisation. When supported on solid polymeth
