A rodlike polymer with various side chain lengths was prepared in a good qu
ality of films. The polymer films were rubbed, and used in constructing liq
uid-crystal (LQ cells which were filled with a nematic LC containing a dich
roic dye. For the LC cells, the ability of polymers to align LCs was evalua
ted, and compared to that of semi-rigid polymer containing the same type of
side chains as the rodlike polymer had.
