Abstract
The present specification discloses a method for treating a thermoplastic resin composition containing a flame retardant comprising a dissolving or dispersing step of bringing the thermoplastic resin composition containing a flame retardant into contact with a solvent to dissolve or disperse at least one portion of the flame retardant into the solvent. According to this, a thermoplastic resin composition containing a flame retardant can be easily separated into a flame retardant and a thermoplastic resin in their original states.
