摘　　要：在水溶液聚合的条件下,利用磺甲基化原理,对共聚物PDA进行磺化改性,全面探讨影响磺化后产物相对分子质量的因素,对比分析磺化前后产品红外谱图。实验表明,磺化改性的较佳条件为:磺化温度为60℃、n(AM)∶n(HCHO)∶n(Na2SO3)=1∶0.5∶1、磺化时间为4 h、磺化反应pH为8,合成SPDA分子量为4.39×105。Under the conditions with solution polymerization, with the principal of sulfomethylation, PDA was modified by sulfonated. The factor influenced the relative molecular mass of sulfonated product was comprehensively studied, comparing the IR of product that sulfonated with the IR of product that after sulfonated. The result showed the sulfonated modified for better conditions were that sulfonation temperature was 60 °C, n（AM） ： n（HCHO） ： n（ Na2SO3 ） = 1 ： 0. 5 ： 1, sulfonated time was 4 h, sulfonation reaction pH was 8, and the relative molecular mass of SPDA was 4.39 x 105.
