Polythiirane containing pendant mesogenic stilbene units was synthesized by
ring opening polymerization of the corresponding monomer. The synthetic co
nvergent pathway used for the monomer synthesis involved several steps incl
uding a Wittig reaction in order to obtain the stilbene unit. The insoluble
polymer was characterized by high resolution CP/MAS 13C NMR. The thermotro
pic liquid crystalline mesomorphism of the polymer was studied by conventio
nal methods. A mechanical dynamical thermal analysis completes the polymer
characterization.
