摘要： A process for reclaiming waste plastics having a paint film which includes subjecting the paint film to a hydrolysis treatment by immersing the waste plastics having a urethane paint film or an amino resin paint film in a treating liquid, or contacting the waste plastics with the vapor of a treating liquid, to decompose the paint into lower molecular weight compounds. The resulting waste plastics are then heated and kneaded to disperse the products of the hydrolysis in the waste plastics, and there is recovered a reclaimed waste plastics product having good mechanical properties.
