Abstract

Synthesis and Polymerization Behavior of Various Substituted Indenyl Titanium Complexes (I) as Catalysts for SyndiotacticPolystyrene.-All title compounds (I) yield, in the presence of the cocatalyst methylaluminoxane, extremely pure syndiotactic polystyrene with conversion rates of ≥ 95%. The catalytic properties are compared with the data obtained from the (η5-indenyl) trichlorotitanium-methylaluminoxane system. The catalytic activity is enhanced by less bulky and more electron-releasing substituents of the indenyl ligand. -(KIM, Y.; KOO, B. H.; DO, Y.; J.
