## Abstract Olefin polymerizations were conducted with novel multimetallic zirconocene catalyst systems: RCpCpZrCl~2~ (1) (R = dimethylsilylferrocene; Cp = cyclopentadienyl) and (RCp)~2~ZrCl~2~ (2) in combination with methylaluminoxane or tetrakis(pentafluorophenyl) borates. In ethylene polymeriz
