Abstract
1333759 Polymerization catalyst for α-olefins FARBWERKE HOECHST AG 16 Nov 1970 [17 Nov 1969] 54405/70 Heading C3P [Also in Division C2] Olefins of formula RCH = CH 2 , where R is hydrogen or a hydrocarbon group, especially C 1 -C 10 alkyl, are polymerized using a catalyst comprising (A) the reaction product of a tetravalent, halogen-containing titanium compound with a complex metal alkoxide, optionally mixed with a simple alkoxide, or with two simple alkoxides in succession, and (B) an organoaluminium compound. The complex alkoxides may be of the general formula where each of M<SP>1</SP>, M<SP>11</SP> and M<SP>111</SP> represents a metal of main- or sub-groups I to V, Fe, Co or Ni, R represents one or more C 1 to C 20 hydrocarbon groups, y is 2 to 6, z is 0 or 1, (v+w) is at least 1 and x is 1 to 5. The complex alkoxides, which need not be isolated before treatment with the titanium compound, may be prepared by (i) reaction between the simple alkoxides of M<SP>1</SP> and M<SP>11</SP>, (ii) dissolving one metal in an alcohol in the presence of a simple alkoxide of the other, (iii) dissolving both metals together in an alcohol, (iv) reacting the acid of the anion [M<SP>1</SP> x (OR) y ] with an alkaline simple alkoxide of M<SP>11</SP> or (v) reacting an anhydrous metal halide, M<SP>1</SP>X n , with an alkali metal alkoxide, M<SP>11</SP>(OR). In the examples, complex alkoxides are obtained by reacting (i) Mg(OEt) 2 with Ti(Oi-Pr) 4 or Al(Oi-Pr) 3 or Al(O sec-Bu) 3 ; (ii) Ti(Oi-Pr) 4 with Li(Oi-Pr) and Mg(OEt) 2 or Al(Oi-Pr) 3 and Mg(OEt) 2 ; (iii) lithium metal with an isopropanol solution of Al(Oi-Pr) 3 , followed by addition of Mg(OEt) 2 ; (iv) titanium glycolate with Mg(OEt) 2 and Al(Oi-Pr) 3 ; and (v) ZrCl 4 with Mg(OEt) 2 . The complex alkoxides are then treated with TiCl 4 , washed, activated with Et 3 Al, Et 2 AlCl or (i-Bu) 3 Al and used to catalyse the homopolymerization of ethylene or copolymerization of ethylene and 1-butene in a hydrocarbon diluent. The gas-phase polymerization of ethylene is also described.
