AbstractDichlorobis(substituted-1,3-diketonato)titanium complexes 4a-e have been synthesized and were combined with methylaluminoxane as cocatalyst to be employed in the polymerization of styrene. The polystyrenes produced have high syndiotacticities of 94.0-98.2%. The substituents at either 2- or 1,3-positions of 1,3-diketones can noticeably influence catalyst activities. The catalytic activities of 4a-c bearing 2-substituents and 4e bearing 1,3-diphenyl groups are tenfold higher than that of 4d bearing 1,3-dimethyl groups. The effects of polymerization conditions on the catalyst activities and the syndiotacticities of the polystyrene produced have been examined. (C) 2000 Society of Chemical Industry.
