Abstract

1348655 Supported Zeigler olefin polymerization catalyst MONTECATINI EDISON SpA 19 May 1971 [22 May 1970 (3)] 15733/71 Heading C3P Olefins are polymerized in the presence of a catalyst which is the reaction product of (a) an organometallic compound or hydride of Groups I, II or III and (b) the reaction product of an "activated" magnesium halide with a titanium compound, wherein the latter compound contains a Ti-X bond where X is a carbon or sulphur atom, a boron atom of a BR 4 (R is hydrogen or hydrocarbyl), or an oxygen atom bound to a radical of an inorganic acid or a sulphuric acid or bound to the trimethylsilyl radical. The magnesium halide may be obtained in the desired "activated" form by grinding prior to or during admixture with the titanium compound or by formation from heating a Lewis base or acid complex thereof, or from a disproportionation reaction of a Grignard reagent or reaction of the latter with a halogen-containing compound such as HCl. In Examples, conventional Zeigler-type homopolymerizations of ethylene in the presence of hydrogen are performed using catalysts comprising the reaction products of (a) and (b) MgCl 2 -C 5 H 5 .TiCl 3 , C 6 H 5 .S.TiCl 3 , the N,N - diphenyl - thiocarbamate of titanium dichloride,
