摘　　要：以环氧苯乙烷(SO)为单体合成了不同分子量的预聚体聚环氧苯乙烷(PSO),再分别与不同比例浓硫酸进行磺化,得到一系列不同磺化度的阴离子-非离子两性高分子聚环氧苯乙烷磺酸聚醚(SPSO)。结构表征结果表明,PSO的分子量为4030到4950,随着引发剂量的减小,分子量呈递增趋势;SPSO除苯环部分磺化外,主链部分也发生磺化,且主链磺化趋势大于苯环,主链磺化度为200%,其总磺化度范围为287%到365%,随着浓硫酸量的增多总磺化度相应增大。In this paper, a serious of prepolymer （PSO） with different molecular weight were synthesized via the styrene oxide（SO）, the sulfonated polyether（SPSO） with various sulfonation degree were synthesized via the sulfonation of PSO with different ratios sulfuric acid. The polymer and sulfonate were characterized with VPO, ^1H-NMR, FT-IR. The result showed that the average molecular weight of PSO were increased as the reducing of initiator amount, the range of molecular weight were 4030-4950. The main chain and benzene ring of PSO were both sulfonated, and the sulfonation tendency of main chain is more stronger than benzene ring. The sulfonation degree of main chain is 200%, the total sulfonation degree of SPSO were in the range of 287%-365%. The total sulfonation degree were increased as the increasing of the amount of sulfuric acid.
