ABSTRACT:
A process is provided for producing efficiently an optically active liquid crystalline polymer compound excellent in mechanical strength or optical characteristics at low cost, in which in that a liquid crystal polymer compound having in its main chain or side chain an ester bond is reacted with an optically active low molecular weight compound having a hydroxyl group so as to introduce the low molecular weight compound in the polymer compound as a unit having an optically active group.
