There is disclosed a high-activity catalyst made from a vanadium compound, preferably VCL4 or VOCL3, specially precipitated with an organoaluminum (i.e. AIRnCl3-n, R is C2-C4, n is 1, 2, 3) in an alkylhalide solvent on a unique, alcohol-activated MgCl2 support, and the use of said supported catalyst for olefin polymerization. This supported catalyst is particularly suited for manufacturing noncrystalline homogeneous copolymers and terpolymers of ethylene with alpha-olefins.
