dc.description.abstractPropylene was polymerized with two C2symmetric metallocene catalysts, ethylene bis(indenyl)zirconium dichloride and dimethylsilyl bis(2- ethyl-benz(e) indenyl) zirconium dichloride, in the presence of increasing amounts of hydrogen. The hydrogen influenced the molecular weight significantly, as was expected. The degree of isotacticity of the polypropylene was influenced by the level of hydrogen added during polymerization, and the amount and type of stereoerrors as determined by 13C NMR increased as hydrogen levels were increased. Results indicated that efficiency of enantiomorphic site control is dependent on the length of the growing polymer chain during polymerization.
