| 摘 要： | 通过溶液共混法制备热致液晶共聚酯（HTH－6）和尼龙66(PA-66)共混物，用DSC对共混物进行了表征，考察了在不同条件下所得到的共混物的熔融和结晶行为以及HTH－6的加入对PA－66的影响。DSC结果表明，HTH－6的加入影响了PA－66的熔融与结晶行为，少量的HTH－6有利于PA－66的结晶，HTH－6掺入到PA－66的结晶过程；HTH－6的含量为75％时，两种条件下获得的共混物的熔融与结晶行为有较大差别。 |

| Abstract: | The melting and crystalliztion blends were prepared by solution blending. The melting and crystallization behaviors of thermotropic liquid crystalline copolyester(HTH-6) / PA-66 blends were investigated with DSC. The results show that the melting and crystallization behavior of PA-66 is affected by HTH-6. The crystallization of PA-66 is induced by HTH-6, and a little amount of HTH-6 can acts as nucleate agent. The degree of crystallization of blends in cast film at 50 ℃ is higher than that of the co-precipitation, but the former’s melting temperature is lower than the latter’s. |
