PROCESS FOR PRODUCING STYRENE-BASED POLYMERS AND CATALYST FOR USE THEREIN |
摘要 |
A process for producing styrene-based polymers having mainly syndiotactic configuration in the presence of a catalyst comprising (A) a titanium compound and (B) a contact product of a methyl group-containing organoaluminum compound and water, wherein the contact product (B) has a high magnetic field component of not more than 50% in the methyl proton signal region due to an aluminum-methyl 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.
