Synthesis of ultra-high molecular weight poly(ethylene)- co -(1-hexene) copolymers through high-throughput catalyst screening

Synthesis of ultra-high molecular weight poly(ethylene)- co -(1-hexene) copolymers through high-throughput catalyst screening

A family of permethylindenyl titanium constrained geometry complexes, Me SB( N, I*)TiX ((3-R-η -C Me )Me Si( TiX )), supported on solid polymethylaluminoxane (sMAO) are investigated as slurry-phase catalysts for ethylene/H homopolymerisation and ethylene/1-hexene copolymerisation by high-throughput...

Zusammenfassung:A family of permethylindenyl titanium constrained geometry complexes, Me SB( N, I*)TiX ((3-R-η -C Me )Me Si( TiX )), supported on solid polymethylaluminoxane (sMAO) are investigated as slurry-phase catalysts for ethylene/H homopolymerisation and ethylene/1-hexene copolymerisation by high-throughput catalyst screening. Me SB( N,I*)TiCl supported on sMAO [sMAO-Me SB( N,I*)TiCl ] is responsive to small quantities of H (
