中文摘要：

用丁腈橡胶（NBR）作基体，分别研究了在NBR中原位生成丙烯酸锂（LiAA）及在NBR／LiAA中添加氯化镧（LaCl3）后，硫化胶体系电学性能的变化。结果表明，在NBR中原位生成LiAA，可降低NBR的体积电阻率。使其由绝缘材料转变为抗静电材料；进一步在NBR／LiAA中添加LaCl3。体系体积电阻率继续降低，在LaCl3用量为20份左右时，体系体积电阻率有一最低值并趋于稳定。

英文摘要：

The in situ preparation of lithium acrylate （LiAA） in nitrile rubber （NBR） and the effect of lanthanum acrylate （LaCl3） on the electrical resistivity of NBR/LiAA composites were investigated. The results indicated that the in situ prepared LiAA could decrease the volume electrical resistivity and changed the composites from insulated to antistatic; the volume electrical resistivity continued to decrease after LaCl3 was added to NBR/LiAA composites. The volume electrical resistivity reached the minimum when about 20 phr LaCl3 was added.
