Title:
PHOTOCROSSLINKABLE LIQUID CRYSTALLINE POLYMER, AND PHOTOCROSSLINKABLE LIQUID CRYSTALLINE POLYMER MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2018/096724
Kind Code:
A1
Abstract:
Provided is a novel liquid crystalline polymer that is produced by separating forming and curing (crosslinking). A photocrosslinkable liquid crystalline polymer that, before photocrosslinking, has a melt viscosity of 5-1000Pa∙s when measured in an environment with a temperature of 80-120°C and a shear rate of 500s-1, said photocrosslinkable liquid crystalline polymer including a reaction product of an isocyanate compound, a photopolymerizable group-containing compound, a photocuring initiator, and a mesogenic group-containing compound that has an active hydrogen group, wherein the mesogenic group-containing compound that has an active hydrogen group is a compound expressed by general formula (1) (wherein X is an active hydrogen group, R1 is -N=N-, -CO-, -CO-O-, -CH=N-, or a single bond forming a part of neighboring bonded groups, R2 is -O- or a single bond forming a part of neighboring bonded groups, and R3 is a C1-20 alkylene group or a single bond forming a part of neighboring bonded groups. However, a case in which R2 is -O- and R3 is a single bond forming a part of neighboring bonded groups is excepted).
