The synthesis and characterization of liquid‐crystalline polymers with possible good adhesive properties is reported. These polymers are prepared by alternating copolymerization of maleic anhydride and mesogenic alkenes. The spacer length m is varied (m = 2, 3, 4, 6, 8 and 9) and methoxybiphenyl is used as the mesogenic group. The glass transition temperature decreases and the isotropization temperature increases with spacer length. Depending on the spacer length and temperature, S B and S Ad mesophases can be observed. After annealing, spin‐coated films of these polymers show very regular layered structures with a layer spacing similar to that in the bulk.
