Abstrakt: Summary The complex ? 5-(C 5H 5) 2Ti (? 1-OC(O)C 6H 5) 2 was synthesized and activated with MA0 for ethylene polymerization. The resultant polymer is UHMW-PE with a viscosimetric molecular weight of Mv = 6.8 x 10 6 to 0.7 x 10 6 g/mol dependent on the temperature of the reaction. The effects of the Al/Ti molar ratio and temperature of the reaction on the catalytic activity and polymer properties were studied. [ABSTRACT FROM AUTHOR]
