Title:
POLYMER AND METHOD FOR PRODUCING POLYMER FILM
Document Type and Number:
WIPO Patent Application WO/2018/135139
Kind Code:
A1
Abstract:
In order to obtain a cross-linked cellulose without requiring a derivatization process, the polymer of one embodiment of the present disclosure has a structure in which a cellulose substantially represented by formula (c1) is cross-linked by a polyfunctional epoxy compound (in formula (c1), n represents an integer of 2 or more).
