  • Patent number: 4366006
    Abstract: A method for recovering a resin material from a spent commercial article comprises contacting the commercial article with a solution of a dialkyl ketone and tetrahydrofuran, and granulating the resin material, and recovering the resulting resin granules. The present method is useful for the recovery of synthetic resins including polyolefins, polycarbonates and vinyl polymers. The granulated resins recovered have a high purity in addition to retaining the properties and composition of the original resin material, and little or none of the solution utilized in the recovery process is lost. In the instance where the resin is being removed from a metal substrate, the surface of the substrate is undamaged and perfectly clean, and the recovery solution is free from metallic particles.
