Abstract
A polymerization catalyst comprises the reaction product of an organo-aluminium compound and the alcohol adduct of a haloalkoxy compound of titanium of the general formula Ti(hal)2(OR)2.R1OH where hal represents a halogen atom, and R and R1 each represent an aliphatic or araliphatic hydrocarbon radical containing from 1 to 10 carbon atoms. Exemplified adducts are those in which R and R1 are both isobutyl, methyl, ethyl, and isopropyl, and those in which R is isobutyl and R1 is CH3-, C2H5-, (CH3)2CH-, C4H9-, C6H5-CH2-, and C6H11-. The exemplified organoaluminium compound is ethyl aluminium sesquichloride. The catalyst which is preformed, is used to polymerize ethylene in the presence of an inert hydrocarbon diluent. The polymer is recovered by conventional techniques.ALSO:Alcohol adducts of a halo-alkoxy compound of titanium of the general formula Ti(hal)2(OR)2.R1OH where hal represents a halogen atom, R and R1 each represent an aliphatic or araliphatic hydrocarbon radical containing from 1 to 10 carbon atoms are used as components of polymerization catalyst systems. In Example 1 is described (a) the preparation of adducts in which R1 and R are the same radicals, i.e. TiCl2(O-iso-C4H9)2-iso-C4H9OH is made by reacting 1 mole of TiCl4 with 5.2 mole of isobutanol and recovering the adduct by adding a hydrocarbon fraction boiling at 180-200 DEG C. and distilling off excess butanol. Adducts in which isobutanol is replaced by CH3OH, C2H5OH, and (CH3)2CHOH, were prepared in a similar manner, and (b) the preparation of adducts of the formula TiCl2(O-iso-C4H9).ROH where R represents CH3-, C2H5-, (CH3)2CH-, C4H9-, C6H5-CH2- and C6H11-, by heating to 50 DEG C. TiCl2(O-iso-C4H9)2, obtained from TiCl4 and Ti(O-iso-C4H9)4, with a slight excess of the desired alcohol.
