Abstract

Propylene, butadiene, isoprene or chloroprene may be polymerized using as catalyst an organotitanium compound RnTiX(4-n) wherein R is alkyl, alkaryl, aryl or aralkyl, X is alkoxy or halogen and n is 1 or 2, which catalyst may be produced by reaction of 1 to 2 mols of a metal alkyl or aryl or of a Grignard reagent with 1 mol of an alkyl titanate, a titanium tetrahalide) or an alkoxy titanium halide; the reaction mixture being used as such or the catalyst being separated and stored for subsequent use. Hydrocarbon solvents may be present. In examples the catalysts are obtained as specified; (1) Me2TiCl2 from TiCl4 + MeMgBr + ether, (2) PrTi(OBu)3 from Ti(OBu)4 + PrMgCl, (3) PhTi(OPr)3 from Ti (OBu)4 + PhMgBr + ether, (4) and (5) Ph2Ti (OBu)2 from Ti(OBu)4 + PhMgBr.
