Liquid‐crystalline AB‐block copolymers poly[6‐(4′‐methoxy‐4‐biphenylyoxy)hexyl methacrylate]‐ block ‐polystyrene were synthesized by direct coupling of the homopolymers with functional end groups. Like the liquid‐crystalline homopolymer with mesogenic units in the side chain, all block copolymers show a nematic mesophase. The transition temperatures are hardly affected by the composition and molecular weight of the block copolymers.
