ABSTRACT OF THE DISCLOSURE A process for production of styrene polymers of high syndiotactic configuration is disclosed, comprising poly- merizing styrene or styrene derivatives by the use of a catalyst comprising: (A) a titanium compound, e.g., at least one compound selected from those represented by the formulae: TiR1aR2bR3cX14-(a+b+c) and TiR1dR2eX13-(d+e) (all the symbols are as defined in the appended claims); and (B) a contact product of an organoaluminum compound and a condensation agent, e.g., a product resulting from modification of trimethylaluminum with water. Because of such high syndiotactic configuration, the styrene polymers are greater in thermal resistance and solvent resistance than conventional atactic polystyrene.
