    Abstract: A cured epoxy resin material is depolymerized by using a composition including a compound represented by the chemical formula of XOmYn (wherein X is hydrogen, alkali metal or alkaline earth metal, Y is halogen, m is a number satisfying 1≤m≤8 and n is a number satisfying 1≤n≤6), and a reaction solvent, wherein X is capable of being dissociated from XOmYn and Y radical is capable of being produced from XOmYn in the reaction solvent. It is possible to carry out depolymerization of a cured epoxy resin material, for example, at a temperature of 200° C., specifically 100° C. or lower, and to reduce processing cost and energy requirement. It is also possible to substitute for a reaction system using an organic solvent as main solvent, so that the contamination problems caused by the organic solvent functioning as separate contamination source may be solved and environmental contamination or pollution may be minimized.

    Abstract: A cured epoxy resin material is depolymerized by using a composition including a compound represented by the chemical formula of XOmYn (wherein X is hydrogen, alkali metal or alkaline earth metal, Y is halogen, m is a number satisfying 1≦m≦8 and n is a number satisfying 1≦n≦6), and a reaction solvent, wherein X is capable of being dissociated from XOmYn and Y radical is capable of being produced from XOmYn in the reaction solvent. It is possible to carry out depolymerization of a cured epoxy resin material, for example, at 200° C., specifically 100° C. or lower, and to reduce a processing cost and an energy requirement. It is also possible to substitute for a reaction system using an organic solvent as main solvent, so that the contamination problems caused by the organic solvent functioning as separate contamination source may be solved and environmental contamination or pollution may be minimized.

    Abstract translation: 固化的环氧树脂材料通过使用包含由化学式XOmYn表示的化合物的组合物（其中X是氢，碱金属或碱土金属，Y是卤素，m是满足1≤m≤8且n 是满足1≤n≤6的数），并且其中X能够从XOmYn和Y自由基解离的反应溶剂能够在反应溶剂中由XOmYn产生。 例如可以在200℃，特别是100℃以下进行固化环氧树脂材料的解聚，降低加工成本和能量需求。 也可以用有机溶剂作为主要溶剂代替反应体系，从而可以解决有机溶剂作为单独的污染源发挥的污染问题，并且可以使环境污染或污染最小化。
