摘　　要：聚离子液体兼备了离子液体和聚合物的优良性质和结构特点,正成为新的研究热点。本文以4-乙烯基吡啶(VP)和二乙烯基苯(DVB)为单体,过二硫酸钾(KPS)为引发剂,通过乳液聚合的方法制备了吡啶基聚离子液体。采用红外光谱分析法、热重分析等表征了聚离子液体的结构以及热稳定性,同时利用Kissinger法对吡啶基聚合离子液体的热降解动力学进行了研究。Polyionic liquids have the excellent properties of ionic liquids and polymer,therefore,the studies on polyionic liquids has attracted significant attention in recent years.In this paper,polyvinylpyridine was prepared by emulsion polymerization with 4-vinylpyridine(VP)and divinylbenzene(DVB)as monomer,potassium perdisulfate(KPS)as initiator.The structure and thermal stability of polyvinylpyridine were characterized by infrared spectroscopy and thermogravimetric analysis.The thermal degradation kinetics of polyvinylpyridine were studied by Kissinger analysis.
