Popis: | A change in the X-ray patterns of unoriented poly(ɛ-caproamide) films cast from poly(ɛ-caproamide) solutions in formic acid in the presence of 1,1,5-trihydroperfluoropentanol has been examined. It has been shown that the polyfluorinated alcohol increases the proportion of polymer molecules in the planar trans conformation owing to their transition from the gauche conformation constituting the amorphous phase and facilitates formation of hydrogen-bonded layers of macromolecules oriented perpendicular to the film plane. |
