PROBLEM TO BE SOLVED: To provide a method for producing a propylene-conjugated diene high mol.wt. copolymer which has carbon-carbon double bonds in side chains and contains 1,2-adducts (including 3,4-adducts) originated from the conjugated diene in a remarkably larger amount than that of 1,4-adducts. SOLUTION: This method for producing the propylene-conjugated diene copolymer having carbon-carbon double bonds in side chains is characterized by copolymerizing the propylene with the conjugated diene in the presence of a prescribed crosslinked metallocene compound, at least one Lewis acid, and a prescribed aluminum halide compound.
