Resum
Basic diffraction data on nylon 47 pointed out a peculiar structure of hydrogen bonds along two directions. Nylon 47 showed reversible polymorphic transitions during heating/cooling processes that were analyzed by real time synchrotron WAXD experiments. Results indicated that nylon 47 had a first structural transition at low temperature, followed by a gradual Brill transition towards a pseudohexagonal packing. Nylon 47 crystallized from the melt giving rise to spherulites with different characte...
