2、—3pS/m增加到545—565pS/m,但储存后柴油电导率没有明显上升。未季铵化的聚胺与聚砜复配时,柴油初始电导率从2—3pS/m增加到495pS/m,储存3d,柴油电导率增加至660pS/m,1周内无明显下降。关键词:部分季铵化聚胺;抗静电剂;电导率;柴油中图分类号:TQ423文献标识码:A文章编号:1671—3206(2014)08—1408一o4Synthesisandanti-staticperformanceevaluationofpartiallyquaternizedpolyamineHUYi-peng,WANGChuan,Zhi-feng,ZHANFeng—tao(Colle
