Abstract
a -Olefines containing 2 to 12 carbon atoms are polymerized in a hydrocarbon medium using a catalyst of unwashed titanium trichloride and diethyl aluminium chloride in a 1:1 to 2.5 mol ratio. Titanium trichloride is produced by reacting titanium tetrachloride and diethylaluminium chloride in a molar ratio of 1:0.5 to 1:0.7 between 0 DEG and 40 DEG C. Titanium trichloride may be subjected to thermal after-treatment between 80 DEG and 110 DEG C. a -Olefines specified are ethylene, propylene and butane-1. In examples titanium tetrachloride is dissolved in a mixture of saturated hydrocarbons and diethyl aluminium chloride in the same solvent are stirred at 20 DEG C. and the catalyst suspension so produced used without being washed. For the polymerization, this catalyst suspension and diethyl aluminium chloride are placed in a mixture of saturated hydrocarbons and ethylene passed in. The reaction was stopped by adding n-butanol, and the polyethylene suction filtered and steam distilled.
