Abstract
Three novel copolymers, poly[1-(4-(benzothiazole-2-thio-alkyloxy)-biphenyl-4′-oxy)2.3-epoxypropane]s, were synthesized by the reaction of polyepichlorohydrin with obtained monomers, 4-(benzothiazole-2-thio-alkyloxy)biphenyl-4′-ols, in which the number of methylene unit in substitution group of biphenyl group was 2, 4, 6, respectively. The structures of obtained compounds were confirmed by elemental analysis and 1H NMR. The decomposition temperatures of copolymers were near 340 °C. Differential scanning calorimetry (DSC) measurement and polarized optical microscopy (POM) observation showed the resulting copolymers did not exhibit thermotropic liquid crystalline mesomophism and belonged to semi-crystalline substance.
