Abstract

1434778 Supported olefin polymerization catalyst preparation SOC ITALIANA RESINE SIR SpA 18 Dec 1973 [22 Dec 1972] 58615/73 Heading C3P Olefins are polymerized in the presence of a catalyst prepared by (a) activating a thiosulphate of an element of Group II at 350‹ to 700‹ C. for 10 to 30 hours in an inert atmosphere, (b) treating the solid granular-product with a halogen-containing transition metal compound in the liquid (including dissolved) state at 20‹ to 300‹ C. for not less than 30 minutes in quantities such that the granular product is present in amounts of 5 to 20% of the transition metal compound, and (c) contacting the product of (b) with an organometallic or hydride compound of Groups Ia, IIb or IIIb. In examples, MgS 2 O 3 .6H 2 O and CaS 2 O 3 .6H 2 O of specified particle sizes (e.g. such as may be obtained by atomization of an aqueous solution of the salt in a nitrogen stream-Example 8) are activated, treated with liquid TiCl 4 , washed with heptane in some cases, and, mixed with Et 3 Al or EtgAlCl, used to polymerize ethylene, ethylene/propylene or ethylene/butene-1 in heptane, in some cases in the presence of hydrogen, and producing a regular micro-spheroidal polymer in Example 8.
