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，乙烯阳离子交换树脂的环结构和烯烃基团磺酸基团稳定。

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

同时还对缩型磺酸系列高效的骨架及其关系作了分析讨论。
