Abstract: | Block copolymers containing a rigid [oxy(2,6-dimethyl-1,4-phenylene)] block and thermotropic poly[oxyterephthaloyloxy-1,4-phenylene-hexamethylene (or/and decamethylene)-1,4-phenylene] blocks were synthesized. Their structures were examined by means of 1H and 13C NMR and X-ray diffraction, and their liquid crystalline properties investigated by polarizing microscopy. |
