Effect of water on the mechanism of deformation of nylon 6

摘要: Lattice spacings perpendicular to the molecular chain axes and crystallite orientation of dried moist (boiled in water) bulk nylon 6 were determined by x-ray diffraction under tension 30–300 kg./cm.2. The deformation specimen was also measured. lattice are changed reversibly presence water 6, but elastic moduli not affected. modulus direction hydrogen bonds is approximately double its value normal bonds. approaches axes, while several times lower. From these facts, especially from relations between deformation, orientation, principal differences mechanism deduced. results obtained have made possible some general conclusions about crystalline structure linear polymers.
