| 摘 要： | 用示差扫描量热法研究了３种不同分子量的尼龙１０１０样品的等温结晶行为，在所研究的温度范围内，尼龙１０１０的等温结晶过程符合Ａｖｒａｍｉ方程。Ａｖｒａｍｉ指数约为２，基本上与分量及结晶温度无关。随着分子量的增大，尼龙１０１０结晶速率变慢，其片晶的侧面自由能增大。

| Abstract: | The isothermal crystallization behaviors of nylon 1010 with different molecular weights were studied by DSC in this paper. Within the studied temperature scope, the isothermal crystallization behavior of nylon 1010 can be described by Avrami equation. The Avrami parameters are about 2 and independent of molecular weight and crystallization temperature. With the increase of molecular weight, the crystallization rate of nylon 1010 becomes slower and the folded chain surface energy accordingly increases. |
