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，聚苯乙阳离子交换树脂的苯环结构磺酸定。

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

同时还对缩聚型磺酸系列高效减水剂的骨架及其关系作了分析讨论。
