<p>1464451 Olefin polymerization catalyst component CHUBU CHEMICAL Inc 27 Aug 1974 [8 Sept 1973 28 Dec 1973(3)] 37425/74 Heading C3P [Also in Division B1] Olefins are polymerized in the presence of (A) an organometallic compound of Groups I to III and (B) the reaction product of (a) magnesium, (b) an organic compound containing an hydroxyl group, (c) an organic oxygen-containing transition metal (Groups IVa to VIa) compound and (d) a compound containing at least one aluminium-halogen group, e.g. organoaluminium halide or aluminium trihalide. The product (B) may be obtained using additional ingredients such as a triorganoaluminium compound, hydrocarbons (as diluents) and iodine (as catalyst). Examples refer to the homopolymerization of ethylene and to the copolymerization thereof with propylene or butene in the presence of hydrogen and of catalysts prepared from, for instance, (A) i-Bu 3 Al or Et 3 Al, and (B) (a) Mg, (b) EtOH, phenol, octylalcohol, stearylalcohol, cyclopentanol, ethylene glycol and triphenylsilanol, (c) T : (OBu) 4 , Zr(OBu) 4 and OV(OBu) 3 and (d) AlEtU 2 , AlEtCl and AlCl 3 , and in some cases iodine, iodine and butylchloride, and AlEt 3 additionally, using hexane as diluent.</p> |
