Copolymerization with non-conjugated olefins and conjugated dienes using a rare earth catalyst

摘要

(57) in the presence of a rare earth metal catalyst, [Abstract] The present invention relates to a method for copolymerization with non-conjugated olefins and conjugated diolefins. The method is one having advantages and reaction conditions can be varied with high selectivity, a wide range and yield a good space-time.
