Na. Plate et Em. Antipov, EVOLUTION OF THE STRUCTURE OF MESOPHASE POLYFLUOROALK-OXYPHOSPHAZENESAND LIQUID-CRYSTALLINE COPOLYESTERS, Macromolecular symposia, 98, 1995, pp. 341-363
Comparative analysis of the temperature evolution of the structure of
linear organoelement polyfluoroalkoxyphosphazenes and wholly aromatic
main-chain copolyesters was carried out using X-ray analysis, differen
tial scanning calorimetry and dynamic mechanical testing within a wide
temperature range. Experimental observations show that flexible-chain
polyfluoroalkoxyphosphazenes are inclined to formation of the columna
r mesophase and condis crystalline structures, while rigid-chain rando
m copolyesters mainly exhibit peculiar smectic and nematic liquid crys
talline states.
