Crystalline transition of polyamide-10,20 investigated by in situ Fourier transform infrared spectroscopy
Real‐time Fourier transform infrared spectroscopy was used to investigate the crystalline transition of even–even polyamide‐10,20. During the crystalline transition, the intensity of the hydrogen bonds became weak, the twisting of the CCO and CN bonds improved, and the gauche conformation of the C...

description | Real‐time Fourier transform infrared spectroscopy was used to investigate the crystalline transition of even–even polyamide‐10,20. During the crystalline transition, the intensity of the hydrogen bonds became weak, the twisting of the CCO and CN bonds improved, and the gauche conformation of the CH2 sequences increased, along with the strengthening of the vibration of the methylene units. The ordered stacking of methylene segments with the trans‐zigzag conformation gradually became disordered by the insertion of the gauche conformation upon heating. © 2004 Wiley Periodicals, Inc.
