摘　　要：利用示差扫描量热法、动态粘弹谱仪研究了尼龙1212/EPDM-g-MAH共混体系的热行为和动态力学性能。结果表明,增韧剂的加入使尼龙1212更容易结晶,结晶速度增大,结晶温度提高,熔融热焓降低;尼龙1212和增韧剂具有较好的相容性。The thermal and dynamical mechanical properties of nylon 1212/EPDM-g-MAH are studied by means of DSC and DMA. Results indicate that crystallization of nylon 1212 become easy and crystalline velocity and degree increase, and the heat enthalpy decreases after the addition of the toughening agent. DMA results show that there is a good compatibility between nylon 1212 and toughener.
