sulfoacid

The benzene ring and alkene structural group are much more stable than structural group of sulfoacid for the carbonifying process of polystyrene.

在碳化过程中，聚苯乙烯阳离子交换树脂苯环结构和烯烃基团比磺基团。

Moreover, the analysis of the high performance reducing agent series skeletons of condensational sulfoacid series high performance reducing series is obtained in the paper.

时还对缩聚型磺系列高效减水剂及其关系作了分析讨论。
