  • Method of cracking polymeric materials catalyzed by copper
    Patent number: 5728909
    Abstract: The present invention is a method for depolymerizing or "cracking" polymeric materials. The method of the present invention may be used in the disposal and/or recycling of such materials. Products of the degradation of polymeric materials using the present method may be recycled or more easily treated for disposal. The present invention is a process for degrading, depolymerizing or "cracking" a polymeric material, otherwise amenable to cracking by alkali fusion, comprising the steps of:(a) preparing a molten reaction mixture comprising:(i) a basic material;(ii) a source of copper; and(iii) said polymeric material; and(b) maintaining said molten mixture at a temperature sufficient to reflux said molten mixture for sufficient time to depolymerize said polymeric material.
    Type: Grant

  • Method for depolymerization of rubber
    Patent number: 5438078
    Abstract: The present invention is a method for depolymerizing organic vulcanized rubber which contains at least one organic component. In broadest terms, the method of the present invention comprises the steps of: (a) obtaining a portion of organic vulcanized rubber to be recycled; (b) treating the portion of rubber with an effective amount of:(1) a solution of at least one organic hypochlorite; and(2) at least one organic solvent; for sufficient time and at sufficient temperature whereby substantially all of the portion of the rubber is degraded to an extent so as to be dispersed in the organic solvent, whereby the organic component(s) is/are extracted therefrom.The organic vulcanized rubber (such as rubber from used tires and/or other waste sources) may be from a single source or from various sources, and those from various sources may even be comingled for treatment by the present method.
