metallocene catalysts are active in the regioselective ring-opening polymerization of strained exo-methylenecycloalkanes to yield exo-methylene-functionalized polyethylenes. MCB (methylenecyclobutane) affords the polymer [CH2CH2CH2C(CH2)]n under the catalytic action of (1,2-Me2Cp)2ZrMe+MeB(C6F5)3-, and MCP (methylenecyclopropane) affords the polymer [CH2CH2C(CH2)]n under the catalytic action of [(Me5Cp)2LuH]2
