本文采用膨胀计法和差示扫描量热法研究了聚环氧氯丙烷的等温和非等温结晶动力学,並用光学显微镜法研究了结晶的光学性质。结果表明,Avrami指数在3—4之间,最大结晶速率时的温度为50℃,晶体为单轴负光性晶体。
In this paper, the isothermal and non-isothermal crystallization kinetics of polyepichlorohydrin was investigated by dilatometer and differential scanning calorimetry. The optical properties of the crystals were studied by optical microscopy. The results show that the Avrami index is between 3-4 and the maximum crystallization rate is 50 ° C. The crystal is a uniaxial negative lens.
