Abstract

A polymerization catalyst for alpha-olefins comprises (1) a halogen-free titanium compound of the formula <FORM:1024494/C3/1> where m is 0, 1 or 2, n is 1, 2, 3 or 4, and the sum of m and n is equal to the valency of T1, i.e. greater than 2, <FORM:1024494/C3/2> or -N=C=, Y is -CO-R11, -CNH-R11 or -CH; R,R1 amd R11, are hydrogen or an alkyl, aryl, alkylaryl, alkoxy, aryloxy, alkylamino, arylamino or heterocyclic group, or, when Y is -CO-R11, R and R11 together complete a quinone structure so that the grouping <FORM:1024494/C3/3> is <PICT:1024494/C3/1> and R111 is an alkyl or aryl group, and (2) an alkyl compound or hydride of a metal of Group I, II or III of the Periodic Classification. The molar ratio of (2) to (1) is from 0.5 to 20. Component (2) may be Al(C2H5)3, Al(C4H9)3, AlH(C2H5)2, Be(C2H5)2, Li(C4H9), Zn(C2H5)2, or LiAlH4. The catalyst is soluble in hydrocarbon medium and may be preformed or formed in situ. The exemplified olefin is ethylene. The Specification contains a long list of suitable titanium compounds. Exemplified compounds are Ti(OC(C6H5)=CHCHO)3, Ti(OC(C6H5) = CHCOCH3)3, Ti(OCH.C6H4.O)3, Ti(OC(CH3) = CHCN)3, and Ti(OC4H9)2 (OC(CH3) = CHCOCH3)2.ALSO:The preparation of the following halogen-free titanium compounds, suitable for use as polymerization catalyst components are described in the Specification, (1) Ti(OCH.C6H4.0)3 by reaction of TiCl3 with salicylic aldehyde in a benzene medium in the presence of ammonia, (2)Ti(OC(CH3)=CHCN)3 by reacting TiCl3 with cyanacetone which is obtained by hydrolysis of iminoacetoacetonitrile, i.e. dimerized acetonitrile, (3) Ti(OC4H9)2(OC(CH3)=CHCOCH3)2 by reacting TiCl4 with a stoichiometric mixture of acetylacetone and butanol in toluene and in the presence of ammonia, (4) Ti(OC(C6H5)= CHCHO)3 by reacting RiCl3 in toluene, in the presence of ammonia, with benzoylacetaldehyde obtained by condensation of acetophenone with ethyl formate in the presence of sodium ethylate in an ethereal medium, and (5) Ti(OC(C6H5)= CHCOCH3)3 by reacting TiCl3 with benzoylacetone in benzene, in the presence of ammonia.
