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

ABSTRACT: A family of permethylindenyl titanium constrained geometry complexes, Me₂SB(^R'N,^3-RI*)TiX₂ ((3-R-η⁵-C₉Me₅)Me₂Si(^R'TiX₂)), supported on solid polymethylaluminoxane (sMAO) are investigated as slurry-phase catalysts for ethylene/H₂ homopolymerisation and ethylene/1-hexene copolymerisation by high-throughput catalyst screening. Me₂SB( ^tBuN,I*)TiCl₂ supported on sMAO [sMAO-Me₂SB( ^tBuN,I*)TiCl₂] is responsive to small quantities of H₂ (<1.6%), maintaining high polymerisation activities (up to 4900 kg_PE mol_Ti ^-1 h^-1 bar^-1) and yieldin
