Abstract
Copolymers of ethylene and propylene having a crystalline content of less than 20% and containing between 35 and 80% combined propylene and less than 1% by weight of low molecular weight normally liquid polymeric oils soluble in boiling acetone are made by contacting a mixture of ethylene and propylene containing from 0,5 to 5 moles of propylene per mole of ethylene in the presence of a trialkyl aluminium compound and the purple form of titanium trichloride or vanadium trichloride, and a nonpolar solvent. Solvents mentioned are heptane, octane, cyclohexane, benzene, toluene, and chlorobenzene. The exemplified trialkyl aluminium compound is triisobutyl aluminium. The polymerization reaction is terminated by the addition of ethanol. Specification 810,023 is referred to.
