摘要: In this study, two new thermotropic liquid crystalline phosphorus-containing polymers were prepared by polycondensation reaction of 1,4-phenylene-bis((6-oxido-6H-dibenz[c,e][1,2]oxaphosphorinyl)carbinol) with different phosphonic dichlorides, namely ethyl dichlorophosphate and phenyl dichlorophosphate. The characterized means FT-IR, 1H NMR, differential scanning calorimetry, polarized light microscopy, wide-angle X-ray diffraction, thermogravimetric analysis. Thermogravimetric analysis was performed in nitrogen atmosphere heating the samples over a range temperatures from 25° to 700°C using five rates. kinetic processing data achieved Freeman-Carroll, ASTM E1641, Kissinger methods.
