从绿色化学的角度来看，亚临界或超临界流体已成为环境应用的反应介质。废塑料的化学回收是一个重要的问题。我们应用亚临界或超临界条件下在水或有机溶剂中的反应将聚合物转化为其单体。缩聚物如聚对苯二甲酸乙二醇酯或尼龙6通过在超临界水或乙醇中醇解的水解作用解聚为其单体。其他聚合物如酚醛树脂和纤维增强塑料（FRP）也通过溶剂分解分解成小分子。本文对本课题组研究的聚合物降解进行了综述。 (c) 2006 年施普林格科学 + 商业媒体公司。
Sub- or supercritical fluids have been focused as reaction media for environmental applications from a view point of green chemistry. Chemical recycling of waste plastics is important issue. We have applied reaction in water or organic solvent in sub- or supercritical condition to convert polymers into its monomers. Condensed polymers such as polyethylene terephthalate or nylon 6 were depolymerized to its monomers by hydrolysis of alcoholysis in supercritical water or alcohol. The other polymers such as phenol resin and fiber reinforced plastics (FRP) were also decomposed to small molecules by solvolysis. In this paper, the degradation of polymers studied in our group was reviewed. (c) 2006 Springer Science + Business Media, Inc.
