Production of styrene polymer

Abstract

Abstract PURPOSE:To obtain the titled polymer where the stereoregular structure of side chains have a syndiotactic configuration, by polymerizing styrene (derivative) in the presence of a catalyst component comprising a titanium compound and a specified product of contact. CONSTITUTION:An organoaluminum compound (e.g., trimethylaluminum) is contacted with a condensing agent (e.g., water) to obtain a product of contact (ii). A titanium compound (i) selected from titanium (chelate) compounds of formulas I and II [wherein R<1-3> are each H, a 1-20C alkyl, a 1-20C alkoxy, a 6-20C aryl, an alkylaryl, arylalkyl, a 1-20C acyloxy, a (substituted) cyclopentadienyl or indenyl, X<1> is a halogen, a, b and c are each 0-4, and d and e are each 0-3] is contacted with component (ii) at a molar ratio of Al of component (ii) to Ti of component (i) of 1-10<6> to obtain a catalyst component. Styrene (derivative) is polymerized at 0-90 deg.C in the presence of this component.
