Structural changes in polycaproamide during thermal drawing of industrial fibres

It was shown that in going from the mesomorphic γ-modification of PA-6 to the stable α-form, formation of intermediate structures can play an important role. It was found that the formation of the polymorphous α-modification in conditions of heat treatment at 180°_C takes place due to the amorphous regions of the polymer. __________ Translated from Khimicheskie Volokna, No. 6, pp. 15–17, November–December, 2007.
