Abstract
1492131 Olefin polymerization catalysts HOECHST AG 28 Feb 1975 [1 March 1974 30 Jan 1975] 8561/75 Heading C3P Olefins containing 3-10 carbon atoms may be polymerized in the presence of catalysts formed by reacting a dialkyl aluminium chloride with titanium tetrachloride in a molar ratio of 0À8: 1 to 1À5: 1 in an inert hydrocarbon at -20 to +20 C., separating the solid reaction product and washing with an inert hydrocarbon, subjecting it to thermal treatment in suspension in an inert hydrocarbon in the presence of a dialkyl ether and after-treating the product obtained with an alkyl aluminium halide, separating and washing the product with an inert hydrocarbon when the aluminium alkyl halide is other than an aluminium dialkyl halide, and mixing the resulting product with a dialkyl aluminium halide and optionally a cyclopolyene. Polymerization may be effected in the presence of hydrogen. Examples describe the polymerization of propylene and 4-methylpentene-1 and copolymerization of propylene with ethylene in the presence of catalysts formed by reducing titanium tetrachloride with ethyl aluminium sesquichloride, thermally treating the product in the presence of di-n-butyl ether, after-treating the product with diethyl aluminium chloride, ethyl aluminium dichloride or ethyl aluminium sesquichloride, adding diethyl aluminium chloride and optionally cycloheptatriene-1,3,5 or cyclo-octatetraene-1,3,5,7.
