The authors report on the efforts to broaden the scope of the particular polymerization process using highly reactive, efficiently prepared methylenecyclopropane and organolanthanide catalysts of the type (Cp′2LnH)2 (Cp′ = η5-Me5C5; Ln = lanthanide), the activities of which can be significantly varied with the Ln3+ ionic radius. Results represent an attractive elaboration of the scope of exo-methylenecycloalkane ring-opening Ziegler polymerization. Both a more readily available and reactive monomer as well as tunable organo-f-element are shown to be compatible with such routes to exo-methylene-functionalized polyolefins.
