Abstract: For depolymerization of a cured epoxy resin material, used is a composition including a transition metal salt or a transition metal oxide containing a transition metal element (metal element that belongs to Groups 3-12 in the Periodic Table). In the reaction solvent, an oxidation occurs by the medium of the transition metal element so that the cured epoxy resin material may be depolymerized and decomposed. In this manner, it is possible to carry out depolymerization of a cured epoxy resin material at a temperature of 200° C., specifically 100° C. or lower very simply and rapidly, and to reduce the processing cost and energy requirement.

Abstract: Disclosed is a liquid crystalline epoxy compound wherein an epoxy group is positioned at a side chain of the longer direction of a mesogen group and each of the mesogen group and the epoxy group is connected to the center of the molecular structure through a flexible linkage. Since the liquid crystalline epoxy compound includes an epoxy group positioned at a side chain of the longer direction of a mesogen group and each of the mesogen group and the epoxy group is connected to the center of the molecular structure through a flexible linkage, the interaction between the mesogens in a cured resin product occurs significantly without weakening even after curing, thereby improving the heat conductivity of the resin compound through the active heat transfer between the mesogens.

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.
