Title:
METHOD FOR PRODUCING BLOCK POLYMER
Document Type and Number:
WIPO Patent Application WO/2018/225685
Kind Code:
A1
Abstract:
Provided is a method for producing a block polymer, which comprises: a step for synthesizing a homopolymer by anionically polymerizing a first monomer in the presence of an initiator with use of a flow reactor that is provided with a mixer for two-liquid mixing, said mixer having a flow path which is capable of mixing a plurality of liquid; a step for synthesizing a block polymer by block polymerizing a second monomer, which is different from the first monomer, with the homopolymer; and a step for cleaning the thus-obtained block polymer with use of a solvent which dissolves homopolymers that are obtained solely from the first monomer but does not dissolve the block polymer and homopolymers that are obtained solely from the second monomer.
