Patent ID: 7851514

Claim:
A process for producing a recycled resin, comprising: a first step of obtaining a decomposed resin composition which contains a resin monomer or a derivative thereof by decomposing at least one thermosetting resin selected from the group consisting of a phenol resin, an epoxy resin, a melamine resin and a urea resin in a supercritical or subcritical solvent at a temperature ranging from 100° C. to 500° C. and a pressure ranging from 1 MPa to 60 MPa until the molecular weight distribution (Mw/Mn) of an oligomer contained in the decomposed resin composition ranges from 1.0 to 3.0, and a second step of adding a polyfunctional compound selected from the group consisting of formaldehyde, paraform, trioxane and hexamethylenetetramine to the decomposed resin composition.
