  • Low toxicity solvent system for polyamideimide resins and solvent system manufacture
    Patent number: 9751986
    Abstract: Disclosed is a low toxicity aprotic alkyl amide solvent system used for the manufacture and application of polyamideimide resins, and an efficient method for manufacturing the polyamideimide resins in a solvent system in a single reaction with distillation which allows recycling of intermediate streams. The solvent system can be used for either the manufacture or the dissolution of polyamideimide resins.
    Type: Grant

  • Low toxicity solvent system for polyamideimide and polyamide amic acid resins and coating solutions thereof
    Patent number: 9029441
    Abstract: Disclosed is a low toxicity aprotic alkyl amide solvent system used for the dissolution and application of polyamideimide and polyamide amic acid polymer resins. The solvent system can be used for the dissolution of polyamideimide and polyamide amic acid resins as an efficient method for incorporating these resins into functional coating compositions with the use of the solvent system.

  • Extended life polyimide toner transfer belts
    Publication number: 20070020411
    Abstract: Examination of the side edges of available polyimide show that they are cut or formed on the angle that forms tapered extensions. This invention minimizes such tapered extensions. In the embodiment the side edges are made to be generally perpendicular to the top and bottom surfaces. The perpendicular sides eliminate thin extensions from which cracks can originate.

  • Semiconductive members and belts
    Publication number: 20060118540
    Abstract: A semiconductive member has a polymer body filled with carbon black which is surface modified with azo linked organic molecules having an acid functional group. Control of conductivity is greatly improved and the strength of the member is improved by the reduced amount of filler required.
