综述了近年来离子液体环境下高聚物材料化学降解回收相应产品的研究现状,重点介绍了聚碳酸酯(PC)、聚对苯二甲酸乙二醇酯(PET)、聚β-羟基丁酸酯(PHB)、聚乳酸(PLA)、尼龙6(PA6)及聚乙烯(PE)等材料在离子液体环境下的化学降解方法,同时分析了各种方法的优缺点。最后对离子液体用于聚合物化学降解行为的发展前景进行了展望。

ABSTRACT：The research progresses in chemical depolymerization of polymer materials into corresponding products in presence of ionic liquids were reviewed in recent years. It was focused on chemical degradation methods of some polymers, such as polycarbonate （PC）, poly（ethylene terephthalate） （PET）, poly（β-hydroxybutyrate） （PHB）, poly （lactic acid） （PLA）, nylon6 （PA6）, and polyethylene （PE）, and advantages and disadvantages of these methods were also analyzed. Finally, the development of chemical degradation of polymer materials in presence of ionic liquids was prospected in the future. Keywords： ionic liquid; polymer materials; chemical depolymerization
