The polymer analogous synthesis of new liquid-crystalline side-chain polymers having polystyrene and poly-α-methylstyrene backbones bearing pendant azo-benzene mesogenic groups is described. The effects of various spacer lengths on the mesophase types were examined. Several liquid-crystalline copolymers were also prepared and their mesophase types determined.
