ABSTRACT:
The invention provides a process for producing a recycled resin, which includes: a first step of decomposing a resin composition containing a thermosetting resin in a supercritical or subcritical solvent having a monomer constituting the thermosetting resin or a derivative thereof as an essential component and a second step of adding a polyfunctional compound thereto to process; a recycled resin or a processed and recovered matter obtained according to the process for producing; a recycled resin composition formed from a recycled resin and/or a processed and recovered matter of the resin composition; and a method for recycling a resin composition, which reuses said recycled resin and/or said processed and recovered matter of a resin composition as a raw material of a recycled resin composition.
