✦ Synopsis

A soluble ethylene catalyst were obtained by mixing a methylene dichloride solution of dichlorobislT-cyclopentadienyl) titanium (Cp2TiCI2) with a heptane solution of ethylaluminium sesquichloride (AlzEt3C13) or of diethylaluminium chloride {AIEt2CI). Ethylene was polymerized using these catalysts; the solution was examined by electron spin resonance technique before the polymerization and during the reaction. The catalyst activity remained constant for a long period, and the polymerization went on at the same rate for 6-8 hr. The mechanism of the reaction is discussed.
