Abstract:

The synthesis of three cyclic imino ethers containing mesogenic groups attached to the heterocyclic unit through flexible spacers described. Cationic ring opening isomerization polymerization of the two of them, i.e., 2-4-4-meth-oxy-4-biphenyloxybutyl-2-oxazoline MeOBiph-4-Oxz and 2-6-4-methoxy-4-bi-phenyloxyhexyl-2-oxazoline MeOBiPh-6-Oxz provided thermotropic liquid crystalline LC polyN-acylethylene-imines, while the polymerization of 2-4-4-phenylphenoxy butyl-2-oxazoline BiPh-4-Oxz led to a crystalline polymer.
