水溶性偶氮引发剂的合成与应用进展

Recent research progress on the synthesis and application of water soluble azo initiators

总结了水溶性偶氮引发剂的分类、合成及应用现状。水溶液聚合和乳液聚合是自由基聚合机理重要的实施手段,它们使用环保水来做分散相,可采用水溶性的偶氮引发剂来进行聚合反应。研究表明,相比于油溶性的偶氮引发剂或常规的氧化还原引发体系,水溶性偶氮引发剂不论是在引发、聚合及产品特征方面都有明显的优势。最后对我国水溶性偶氮引发剂的发展提出了一些建议。

The classification,synthesis and application of water soluble azo initiator were summarized.Aqueous polymerization and emulsion polymerization,which are important means for the implementation of free radical polymerizations,use environmentally friendly water as the dispersed phase,thus it can directly use water soluble azo initiator.Research results show that water soluble azo initiator,compared with traditional oil soluble azo initiator and some redox system,has a distinct advantage both in the initiation process,propagation process or the characteristics of the polymer.Some suggestions for China′s development of water soluble azo initiator were proposed.
