自蔓延波聚合研究进展

波聚合是指靠自身反应放热产生的热波维持反应进行而将单体转化为聚合物的聚合方法。由于波聚合不需要外界持续供热、无溶剂排放和反应设备简单,是一种节能无污染的低成本材料制备工艺,极具应用前景。本文综述了从发现波聚合至今已取得的研究成果,包括波聚合机理、聚合波产生并自蔓延的条件、波结构、传播速度、传播模式以及产物特征,并对波聚合工艺用于高分子材料的制备进行了评述。

Recent Developments of Self-Propagating Frontal Polymerization

Frontal polymerization(FP) is a polymer synthesis technique that uses the exothermic reactions to form a self-sustaining wave.Because no additional heat is needed after the initial polymerization,the process has potential advantages over traditional polymerization methods: lower processing costs,less energy input and absence of solvent.These advantages make FP a potential viable option in polymer synthesis.The mechanism of FP,frontal structure,velocity,front mode and properties of polymer produced via FP are reviewed.The future directions of FP research are prospected.
