摘要:
Uranium-containing mixed catalysts containing uranium in the formal oxidation state +4 as uranium salts of carboxylic acids, a Lewis acid, and an organometallic aluminum compound are prepared and can be used for stereospecific polymerization of diolefins or mixtures of diolefins and monoolefins.
