Title:
POLYMER COMPOSITION, LIQUID CRYSTAL ALIGNING AGENT, RESIN FILM, LIQUID CRYSTAL ALIGNMENT FILM, METHOD FOR PRODUCING LIQUID CRYSTAL DISPLAY ELEMENT, AND LIQUID CRYSTAL DISPLAY ELEMENT
Document Type and Number:
WIPO Patent Application WO/2022/107640
Kind Code:
A1
Abstract:
A polymer composition containing a polymer (A) that has a partial structure represented by any of formulas (i-1) to (i-3) and that has a structure obtained by removing R from the partial structure in the main chain. (R is a monovalent organic group having two aromatic hydrocarbon rings and a nitrogen atom (A). In the monovalent organic group, the two aromatic hydrocarbon rings each satisfy at least one of condition (I): one carbon atom of the aromatic hydrocarbon ring bonds directly with the nitrogen atom (A), and condition (II): when the nitrogen atom (A) is included in an aromatic heterocycle, the aromatic hydrocarbon ring and the aromatic heterocycle form a fused ring. One of the two aromatic hydrocarbon rings is conjugated with a nitrogen atom (B) to which *1 is attached. ＊represents a bond.)
