Title:
MANUFACTURING METHOD FOR CELLULOSE DISPERSION BLOCK COPOLYMER, MANUFACTURING METHOD FOR RESIN COMPOSITION, AND MANUFACTURING METHOD FOR MOLDED ARTICLE
Document Type and Number:
WIPO Patent Application WO/2019/088300
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a method with which it is possible to design a greater diversity of cellulose dispersion block copolymers. The present invention pertains to a manufacturing method for a cellulose dispersion block copolymer that has at least a first segment and a second segment, the manufacturing method comprising a step (1) for synthesizing the first segment by reversible complexation mediated polymerization (RCMP), wherein, one of the first and second segments is a segment having cellulose affinity, and the other is a segment having resin affinity.
