| 摘 要： | 以ＴｉＣｌ＿４／ＡｌＥｔ＿３／炭黑催化体系催化乙烯原位聚合，控制聚合效率获得了不同炭黑含量的系列新型导电聚乙烯，材料的测试结果表明，该方法得到的导电聚乙烯在炭黑含量为１０．８％－１５％（Ｗ）时有明显的ＰＴＣ效应，具有较低的临界体积分数，不出现ＮＴＣ效应，而且重现性和稳定性都较好，有明显的应用前景。

| Abstract: | A new conductive polyethylene was obtained through polymerization in situ using TiCl_4/AlEt_3/carbon black as catalyst.The measurement results indicate that the new conductive poly-ethylene with 10.8%-15%carbon black content shows obvious PTC phenomenon,with lowercritical volume fraction and no NTC phenomenon,The conductive polyethylene also has betterreproducibility and stability. |
