Process for producing styrene polymers |
| abstract |
Disclosed is a process for producing a styrene polymer having a syndiotaotic configuration and a wide molecular weight distribution, which is characterized by using as catalyst (a) two or more kinds of titanium compounds and (b) alkylaluminoxane, in the polymerization of styrene monomers. According to the process of the present invention, a styrene polymer which is excellent in physical properties such as heat resistance because of a high syndiotacticity, and also has a wide molecular weight distribution can be obtained. These styrene polymers can be suitably used as materials for various moldings including hollow molding, sheet molding, and film molding. |
