摘要： 用PJ-356型动电容静电计直流法,测定了一系列不同固体聚电解质的电导率,其电导率一般在10-8到10-12(欧姆·厘米)-1范围.阐明了分子量不同、温度不同、聚甲基丙烯酸锂、钠、钾离子半径不同及聚电解质侧链长短不同对电导率的影响.

Abstract: In this paper, first of all, the conductivity of sodium polymethacrylate of different molecular weight has been investigated at different temperatures. Secondly, the conductivity of lithium, sodium and potassium polymethacrylate has been determined at different temperatures, and the effects of ionic radius on conductivity have been compared. Finally, the effects of side chain length of polyelectrolytes on the conductivity have been studied.Conductivity has been determined by means of direct current method. The complex relations between conductivity of polyelectrolyte and molecular weight are showed. Conductivity depends on the number of ion, which disassociate from the chain, and molecular weight. The results of experiment indicate that the relation between conductivity and ionic radius change as the shape of V. Among salts of lithium, sodium and potassium, the sodium is in the lowest. Linear lgo vs. 1/Tplots are obtained for polyelectrolytes.
