摘　　要：本文研究了分解对氟聚苯乙烯聚合体的条件，建立了用离子选择电极法测定对氟聚苯乙烯聚合体中氟含量的方法。对氟苯甲酸加标回收率为99.9%，对氟聚苯乙烯分析结果的相对标准偏差为2.7%。方法简便、准确。This paper investigated the decomposition conditions of p-Fluoropolystyrene and established a new method for determination of fluorine in p-fluoropolystyrene by ion-selective electrode analysis. The recovery per cent of the standard addition of p-Fluorobenzoic acid for this procedure equals 99.9%, the relative standard error is 2.72%. This new method has of the advantages of brief and high accuracy.
