摘　　要：本文以聚苯乙烯为原料,浓硫酸为磺化试剂制备了磺化聚苯乙烯粒子,并考查了磺化时间、磺化温度对磺化度的影响,并采用滴定法测定了磺化度。同时通过了磺化粒子Zeta电位的测定和红外半定量法-SO3H/-Ph峰高比值验证了其磺化趋势与滴定法测定的相一致。The sulfonated polystyrene particles were synthesized by poly-styrene and concentrated sulfuric acid as the sulfonation reagent.The sulfonation reaction time and the sulfonation temperature were investigated to influence the sulfonation degree.The titration method was used to measure the sulfonation degree.Meanwhile,the result of the Zeta potential of sulfonated particles and the ratio of-SO 3H/-Ph peak height by infrared semi-quantification method,were consistent with the titration method.
