Abstract
1376887 Olefin polymerization catalyst SOLVAY & CIE 28 March 1973 [28 March 1972] 14879/73 Addition to 1314784 Heading C3P A catalyst for the polymerization of alphaolefins comprises (a) an organometallic compound of a metal of Group Ia, IIa, IIb, IIIb or IVb and (b) the product of reacting a compound of a metal of Group IVa, Va or VIa with a halogenated complex oxide of aluminium and another metal or silicon. The halogenation and preparation of the catalyst may be carried out by the same methods as those used for the halogenated alumina-based catalyst of Specification 1,314,784. In examples ethylene is polymerized using catalysts derived from (a) Al(i-Bu) 3 and (b) the reaction product of TiCl 4 with MgO.- Al 2 O 3 , MgO.3/2Al 2 O 3 , CaO.Al 2 O 3 , and Al 2 O 3 .- 4SiO 2 , all of which have been fluorinated by heating with NH 4 F.
