Method for manufacturing polymer and flow-type reaction system for manufacturing polymer

A method for manufacturing a polymer by performing an anionic polymerization reaction by a flow-type reaction, including: introducing a liquid A containing an anionic polymerizable monomer, a liquid B containing an anionic polymerization initiator, and a polymerization terminator into different flow paths respectively and causing the liquids to flow in the respective flow paths; causing the liquid A and the liquid B to join together by using a multilayered cylindrical mixer; subjecting the anionic polymerizable monomer to anionic polymerization while a solution formed by the joining is flowing to downstream in the reaction flow path; and causing a polymerization reaction solution flowing in a reaction flow path and the polymerization terminator to join together such that the polymerization reaction is terminated; and a flow-type reaction system suitable for performing the manufacturing method.

The present invention provides a method for manufacturing a polymer by a flow-type reaction. The method includes introducing a liquid A of an anionic polymerizable monomer, a liquid B of an anionic polymerization initiator, and a polymerization terminator into different flow paths, allowing the liquids to flow in the flow paths, allowing the liquid A and the liquid B to join together, subjecting the monomer to anionic polymerization while the liquids having joined together are flowing to downstream in a reaction flow path, and allowing a solution, which is obtained by the polymerization reaction and flows in the reaction flow path, and the polymerization terminator to join together so as to terminate the polymerization reaction and to obtain a polymer having a number-average molecular weight of 5,000 to 200,000. A static mixer is disposed in the reaction flow path, and a polymer having a number-average molecular weight equal to or greater than 2,000 is introduced into an inlet port of the mixer. The present invention also provides a flow-type reaction system suitable for performing the manufacturing method.
