| 英文摘要 | The structure and thermal properties of polyamide-1010 (PA1010), treated at 250degreesC for 30 min under pressures of 0.7-2.5 GPa, were studied with wide-angle X-ray diffraction (WAXD), infrared (IR), differential scanning calorimetry (DSC), and thermogravimetric analysis (TGA). Crystals were formed when the pressures were less than 1.0 GPa or greater than 1.2 GPa. With increasing pressure, the intensity of the diffraction peak at approximately 24degrees was enhanced, whereas the peak at approximately 20degrees was depressed. The triclinic crystal structure of PA1010 was preserved. The highest melting temperature of the crystals obtained in this work was 208degreesC for PA1010 treated at 1.5 GPa. Crosslinking occurred under pressures of 1.0-1.2 GPa. Only a broad diffraction peak centered at approximately 20degrees was observed on WAXD patterns, and no melting and crystallization peaks were found on DSC curves. IR spectra of crosslinked PA1010 showed a remarkable absorption band at 1370 cm(-1). The N-H stretching vibration band at 3305 cm(-1) was weakened. Crystallized PA1010 had a higher thermal stability than crosslinked PA1010, as indicated on TGA curves by a higher onset temperature of decomposition. (C) 2002 John Wiley Sons, Inc. |
