- W1997947915 abstract "Abstract Supported titanium catalysts are prepared by the reactions of magnesium ethoxide and excess titanium tetrachloride with or without an internal Lewis base, dibutyl phthalate. The catalysts are characterized by compositional analysis and BET surface area measurements. The performance of catalysts using triethylaluminum and dimethoxydiphenyl-silane as the cocatalyst system are examined for propylene polymerization in slurry reactions. The dibutyl phthalate and phenyl-substituted methoxysilane used as internal and external Lewis bases, respectively, govern the activity and stereospecificity of the catalyst system. Such polymerization parameters as time, temperature, and hydrogen concentration also influence the performance of the catalytic system in terms of yield, isotactic index, and melt flow index of the polypropylene." @default.
