发明名称 PROCESS FOR PRODUCING STYRENIC POLYMER AND CATALYST THEREFOR
摘要 <p>A catalyst comprising a transition metal compound, such as pentamethylcyclopentadienyltitaniumtrimethyl, and a coordination compound formed between a quaternary ammonium salt and an anion comprising two or more groups bonded to a metal atom, such as O-cyano-N-methylpyridinium tetra(pentafluorophenyl)borate, and another catalyst comprising the above catalyst and an alkylating agent, such as triisobutylaluminum, suitable for the production of a highly syndiotactic styrenic polymer. A process for producing a highly syndiotactic styrenic polymer by polymerizing a styrenic monomer in the presence of the above catalyst. It is thereby possible to produce a highly syndiotactic styrenic polymer efficiently without the necessity for using expensive aluminoxane in a large amount.</p>
