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; t

A fractional poisoning method has shown that all groups of Ziegler catalyst centres, both stereospecific and non-stereospecific, have a similar distribution of propagation rate constants. The most regular and highly molecular isotactic fraction is quite uniform by stereoregularity. Most of the poiso
