Synthesis and Characterization of Liquid Crystalline Poly((N-acylethyleneimine)s.

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'-biphenyloxy)butyl)-2-oxazoline (MeOBiph-4-Oxz) and 2-(6-(4-methoxy-4'-bi-phenyloxy)hexyl)-2-oxazoline (MeOBiPh-6-Oxz) provided thermotropic liquid crystalline (LC) poly(N-acylethylene-imine)s, while the polymerization of 2-(4-(4-phenylphenoxy) butyl)-2-oxazoline (BiPh-4-Oxz) led to a crystalline polymer.
