Three types of surfactants bearing acetal or 1,3-dioxolane ring were prepared by acid-catalyzed condensation of fatty ketones with diol compounds, followed by a reaction with polyethyleneglycol or diethanolamine without any expensive reagents or special equipment. These surfactants had smaller critical micelle concentration (cmc) compared to polyoxyethylene (n=9) dodecyl ether (C12EO9). They were decomposed easily under acidic conditions. After 28 days they were more than 60% biodegradable and were almost the same as sodium dodecanoate. Polystyrene could be synthesized by emulsion polymerization using these chemocleavable surfactants. After emulsion polymerization, the emulsions could be easily broken by adding either HCl. Further, polystyrene could be filtered off very quickly. In the case of type 3, the polydispersities and polymerization degree of the obtained polystyrene were better than those of the polystyrene in the conventional emulsifiers. Further, the Na content values of the former were lower than those of the latter.

在不使用昂贵试剂和特殊设备的条件下，通过脂肪酮与二元醇化合物的酸催化缩合反应，再与聚乙二醇或二乙醇胺反应，合成了3种含缩醛或1，3-二氧戊环的表面活性剂。这些表面活性剂具有较小的临界胶束浓度（cmc）相比，聚氧乙烯（n=9）十二烷基醚（C12 EO 9）。它们在酸性条件下容易分解。28天后，它们的生物降解率超过60%，与十二烷酸钠几乎相同。利用这些化学可切割表面活性剂可以通过乳液聚合合成聚苯乙烯。乳液聚合后，加入HCl或Na 2SO 4均能使乳液破裂。此外，聚苯乙烯可以非常快速地过滤掉。在类型3的情况下，所得聚苯乙烯的多分散性和聚合度优于常规乳化剂中的聚苯乙烯。此外，前者的Na含量值低于后者。
