Process for producing styrenic polymer |
| abstract |
A process for producing a styrenic polymer of, particularly, a syndiotactic structure, which comprises polymerizing a styrenic monomer using a catalyst containing as major components a titanium compound (A) and aluminoxane (B) in the presence of a filler. The filler functions as a catalyst carrier, improving catalyst activity and eliminating the necessity of delimiting treatment. When the filler is used in a large amount, a composition wherein the filler is uniformly dispersed in the polymer is obtained. The obtained styrenic polymer or its composition is excellent in heat and chemical resistances. |
