AbstractA novel ligand (3), in which the indenyl group is linked to a beta-diketone moiety through a three-carbon bridge, and its titanium complex (4) were synthesized. The titanium complex was employed as a metallocene analog with co-catalyst methylaluminoxane (NIAO) in catalytic syndiospecific polymerization of styrene to give highly syndiotactic polystyrene (s-PS, 96%-97%). Polymerization temperature (T-p) strongly influenced the catalytic activity and syndiotacticity of the produced PS. The activities of catalyst 4 increase from 1.84 x 10(6) to 3.26 x 10(6) gPS/molTi . h with the increase of T-p from 60degreesC to 80degreesC and the syndiotacticities of the produced s-PS also increase slightly. Then, both the catalytic activity and the syndiotacticity of PS decrease at T-p of 90degreesC.
