METHOD FOR PRODUCING AROMATIC VINYL COMPOUND POLYMER

摘要

PROBLEM TO BE SOLVED: To provide a method for producing an aromatic vinyl compound polymer having a molecular weight distribution of ≤3 and a syndiotactic structure in the presence of a group 3 transition metal complex with a powder floor continuous polymerization apparatus.SOLUTION: A method for producing an aromatic vinyl compound polymer having a syndiotactic structure using a powder floor continuous polymerization apparatus comprises adding (C) hydrogen to a reaction system in the presence of (A) a group 3 transition metal complex and (B) a catalyst composition including a cocatalyst to produce the aromatic vinyl compound polymer.
