Abstract: 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.

Abstract: Provided is a method for manufacturing a polymer by a flow-type reaction, including introducing a liquid A containing an anionic polymerizable monomer and a non-polar solvent, a liquid B containing an anionic polymerization initiator and a non-polar solvent, a liquid C containing a polar solvent, and a polymerization terminator into different flow paths; allowing the liquids to flow in the respective flow paths; allowing the liquid A and the liquid B to join together at a joining portion; allowing a conjoined liquid MAB of the liquid A and the liquid B to join with the liquid C at downstream of the joining portion; subjecting the anionic polymerizable monomer to anionic polymerization while a conjoined liquid MABC of the conjoined liquid MAB and the liquid C is flowing to downstream in a reaction flow path; and allowing a polymerization reaction solution flowing in the reaction flow path to join with the polymerization terminator so that the polymerization reaction is terminated and a polymer is obtained, in which a polarity of a solvent of the liquid MABC is made higher than a polarity of a solvent of the liquid MAB. Also provided is a flow-type reaction system suited for performing the manufacturing method.
