Catalyst for producing syndiotactic configuration styrene-based polymers |
| abstract |
A process for producing styrene-based polymers having mainly syndiotactic configuration in the presence of a catalyst comprising (A) a titanium compound and (8) a contact product of a methyl group-containing organoaluminum compound and water, wherein the contact product (B) has a high magnetic field componert of not more than 50% in the methyl proton signal region due to an aluminum-mehtyl group (Al-CH3) bond as determined by the proton nuclear magnetic resonance absorption method. According to this process, styrene-based polymers having mainly syndiotactic configuration can be efficiently and economically produced. |
