METHOD FOR PRODUCING AROMATIC VINYL COMPOUND POLYMER

Document Type and Number:

WIPO Patent Application WO/2013/146934

Kind Code:

A1

Abstract:

A method for producing an aromatic vinyl compound polymer having a syndiotactic structure using a powder bed continuous polymerization device, said method comprising polymerizing an aromatic vinyl monomer in the presence of a catalyst composition comprising (A) a Group-3 transition metal complex and (B) an auxiliary catalyst to produce the aromatic vinyl compound polymer, wherein (C) hydrogen is added to the reaction system.
