| 摘 要： | 研究了偶联剂对正温度系数（ＰＴＣ）高分子材料性能的影响，发现偶联剂Ｊ１、Ｊ２在中低温时有较好的分散效果，但高温时较差；耐高温的偶联剂Ｊ３在高温时有更好的分散效果，从而使高分子ＰＴＣ材料有较好的高温性能，但在中低温时稳定性较差，另外，辐照交联可以很好地增加材料的ＰＴＣ强度和降低负温度效应（ＮＴＣ）。从理论上对实验现象进行了定性分析。

| Abstract: | Analyzed is the effect of coupling agents on properties of polymeric PTC materials. It is found that the coupling agents J1 and J2 have better dispersion property than J3 at low temperature. The opposite holds at high temperature. Moreover, the PTC intensity was enhanced and the NTC intensity was decreased by radiation crosslinking. These qualitative results were discussed analytically. |
