Abstract of the Disclosure A process for producing a random terpolymer of ethylene and alpha- olefins having at least 3 carbon atoms in the presence of a catalyst composed of (1) a titanium catalyst component containing at least magnesium and titanium and (2) an organoaluminum catalyst component in a hydrocarbon solvent at a temperature above the melting point of the terpolymer formed, under such condi- tions that the resulting copolymer dissolves in the hydrocarbon solvent; characterized in that said terpolymer consists essentially of (A) more than 90 mole% to 99.5 mole% of ethylene, (B) 0.2 mole% to 9.8 mole% of an alpha-olefin with 3 or 4 carbon atoms, and (C) 0.2 mole% to 9.8 mole% of an alpha-olefin with 5 to 18 carbon atoms, the total of the proportions of the monomers (A), (B) and (C) being 100 mole%.
