Document Type and Number:
WIPO Patent Application WO/2019/031435
Kind Code:
A1
Abstract:
Provided is a method for producing a block polymer, the method including: a step of synthesizing a polymer by subjecting a styrene-based monomer as a first monomer to anionic polymerization in the presence of an initiator using a flow reactor comprising a two-liquid blending mixer provided with a flow path capable of blending a plurality of liquids; and a step of synthesizing a block polymer by block polymerizing an acrylic monomer as a second monomer with the polymer. The flow reactor comprises a two-liquid blending mixer which is provided therein with: a joint member having a double pipe; or a static mixer member.
