Abstract
Olefins, pref. ethylene or propylene are polymsd at 40.80 degrees C and 5-50kg/cm2 in inert hydrocarbon solvent. The solvent is separated before adding polymsn inhibitor and then recycled to the polymsn. zone. Catalyst is in fine particle form dispersed in solvent and consists of titanium trichloride or eutectic with a metallic halide (AlCl3) and an organo Al AlR3-nCln (where R is alkyl; n is 0-1 eg trimethyl aluminium). H is also present.
