Abstract
1456409 Olefin polymerization catalyst BASF AG 19 Dec 1974 [21 Dec 1973] 54852/74 Addition to 1456408 Heading C3P An olefin polymerization catalyst comprises (A) an organoaluminium, -zinc or -magnesium compound and (B) a titanium component obtained by (i) reacting, in suspension, a metal salt of a CH-acid organic compound of formula where M is magnesium or manganese, R<SP>1</SP> is CN, COR<SP>3</SP> or COOR<SP>4</SP>, R<SP>2</SP> is COR<SP>3</SP>, COOR<SP>4</SP> or phenyl, R<SP>3</SP> is alkyl, alkyl phenyl or phenyl and R<SP>4</SP> is alkyl, with an organoaluminium compound, and (ii) reacting, in suspension, the solid product of (i) with a reaction product of the formula TiZ q (OQ) 4-q , where Z is halogen, Q is hydrocarbyl, and q is more than 2À5 and up to 3À8. The titanium halo-hydrocarbyloxide is obtainable by simply mixing compounds of formulae TiZ 4 and T : (OQ) 4 in the ratio q : 4- q. Specified salt compounds are the magnesium salts of acetoacetic acid ethyl ester, acetylacetone, malonic acid diethylester, benzylcyanide and dibenzoylmethane. Examples refer to the homopolymerization of ethylene in a polyethylene bed in the presence of hydrogen and of a catalyst comprising (A) AliBu 3 and (B) (i) Mg salt of acetoacetic acid ethylester and AlEt 2 Cl reaction product, followed by reaction with (ii) TiCl 3À08 (OiPr) 0À92 or TiCl 2À67 (OnBu) 1À33 .
