SIDE CHAIN TYPE LIQUID CRYSTALLINE POLYMER AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a liquid crystalline polymer which has a controllable birefringence. SOLUTION: The side chain type liquid crystalline polymer comprises (a) a monomer unit having a fragmental side chain which has a positive birefringence and (b) a monomer unit having a fragmental side chain which has a lower positive birefringence than the fragmental side chain of the monomer unit (a) does.
