摘要：

Conditions were established on how to prepare an active titanium catalyst based on a bimetallic complex, [MgCl2(C2H5OH)(2)/(C2H5)(2)AlCl], involving ethanol as the internal Lewis base, to polymerize propylene. The catalyst was modified in a prepolymerization run to prepare a precatalyst. The precatalyst was complexed with triethylaluminum used in a high excess and then modified with an external Lewis base, cyclohexylmethyldimethoxysilane, to produce an active and stereoregular catalytic system for polymerization of propylene.
