✦ Synopsis

A description is given of the polymerization of propylene in the presence of catalysts prepared from titanium trichloride and alkyl-alkoxy-aluminium chlorides. These catalyst systems are very active in the propylene polymerization only in the presence of aluminium chloride, which may be present as a solid solution in TiCI3. AI(C2Hs)zCI was isolated from the mixture of reaction products of AICI3 and C2H~AI(C1)OC2Hs. The results lead to the conclusion that the polymerization-active organometallic compound of aluminium is probably aluminium diethylchloride.
