摘要
介绍在己内酰胺阴离子催化聚合反应中,添加六甲基磷酰三胺作增韧改性剂制备改性MC尼龙。用DSC法研究了增韧改性MC尼龙的热性能,结果表明,随着六甲基磷酰三胺组分的增加,MC尼龙的熔融温度、熔融热焓、结晶度等均降低,材料力学性能变化的趋向与热性能变化相吻合。
Hexamethylphosphoric triamide(HPT) was added as toughened modifier in anionic catalytic polymerization of caprolactam to prepare modified MC nylon. DSC method was applied to investigate the thermal property of MC nylon after its toughened modification,and it showed that the melting temperature, the melting enthalpy and the crystallinity of MC nylon were decreased with increasing the content of HPT component, the tendency of variation in mechanical property of material was consistent with variation in thermal property.
