Abstract
PURPOSE:To obtain the titled polymer having syndiotactic structure, heat resistance and solvent resistance, by polymerizing a styrenic monomer in the presence of an inorganic oxide by using a catalyst consisting essentially of a titanium compound and an aluminoxane. CONSTITUTION:A styrenic monomer (e.g. styrene or methylstyrene) is polymerized in the presence of an inorganic oxide (preferably alpha-alumina, titania or tri-iron tetroxide) by using a catalyst consisting essentially of (A) a titanium compound (e.g. methyltitanium trichloride) and (B) an aluminoxane to give the aimed polymer. The blending ratio of the component A and the component B is preferably 10-10<4> calculated as Al/T (molar ratio).
