| Abstract: | A family of ca. 50 imidotitanium precatalysts Ti(NR)(Me(3)9]aneN(3))Cl(2)](R = alkyl or aryl; Me(3)9]aneN(3)= 1,4,7-trimethyltriazacyclononane) were prepared in good yields using semi-automated procedures; high-throughput screening techniques identified seven highly active ethylene polymerisation precatalysts with activities in the range ca. 3 400 to 10 000 kg(PE) mol(-1) h(-1) bar(-1). |
