Polymerization of ethylene in the presence of Cp2Ni (Cp: cyclopentadienyl) and methylaluminoxane affords polyethylene of high molecular weight and with high melting point. The same catalyst is active in the polymerization of styrene and 1,3-butadiene to give partially isotactic polystyrene and 1,4-cis-polybutadiene, respectively.
