  • Polymeric reaction products of biphenols and organosilicon materials and method for making
    Patent number: 5041514
    Abstract: Poly(silyloxytetraalkylbiphenyleneoxide)s are provided resulting from the reaction between a tetraalkylbiphenol, such as tetramethylbiphenol and an organosilicon material such as dimethyldichlorosilane or octamethylcyclotetrasilazane. The poly(silyloxytetraalkylbiphenyleneoxide)s are flame retardant film-forming materials useful as high performance injection moldable thermoplastic and dielectrics.

  • Bisphenol-A dianhydride-based polyimide matrix resins and method of preparation
    Patent number: 4988544
    Abstract: A method for preparing high molecular weight highly thermal and oxidatively stable aryl polyimide compositions is provided which comprises reacting by application of heat, a mixture of bisphenol-A dianhydride, an aromatic diamine and a monoalkyl or dialkyl ester of a dicarboxylic acid or the corresponding anhydride.

    Inventors: James A. Cella, Marsha M. Grade, Thomas L. Evans
  • Alkyl-containing monomers in cross-linkable polyimide compositions
    Patent number: 4675366
    Abstract: An improved method for preparing cross-linked polymers is disclosed, in which at least one alkyl or alicyclic substituent attached to an aromatic radical in the polymer acts as a functional site for oxidative cross-linking. The polymer may be extruded or solvent-deposited directly onto electrical conductors prior to cross-linking. The polymer film may then be cross-linked when exposed to an oxidizing agent and heated at a temperature within the range from the polymer's glass transition temperature to just below its degradation temperature.

  • Aromatic sulfoxy compositions and method for their preparation
    Patent number: 4625013
    Abstract: Aromatic sulfoxy tetracarboxylic acids, and their derivatives such as dianhydrides, bisimides and polyimides, are prepared by oxidizing the corresponding sulfides under relatively mild conditions, using oxidizing agents such as nitric acid, N-chlorosuccinimide, potassium persulfate and hydrogen peroxide. The polyimides may also be prepared by the reaction of the dianhydrides or certain bisimides with diamines.
    Type: Grant

    Date of Patent: November 25, 1986
    Assignee: General Electric Company
    Inventors: Thomas L. Evans, Marsha M. Grade
  • Method for preparing monomeric and polymeric bis(dicarboxyphenyl) sulfone compounds
    Patent number: 4609712
    Abstract: Bis(dicarboxyphenyl) sulfone compounds, including the free tetracarboxylic acids and their functional derivatives such as salts, esters, amides, anhydrides and imides, are prepared by oxidizing the corresponding sulfides with a relatively strong oxidizing agent, preferably a peroxy reagent such as acetyl peroxide or m-chloroperbenzoic acid. The reaction is especially useful for the preparation of sulfone polyimides, since films of the sulfide polyimides may be oxidized without dissolving or otherwise degrading their structural integrity.

  • Novel sulfur-containing polyetherimides
    Patent number: 4429102
    Abstract: Novel polyetherimides containing sulfone units such as those derived from bis(3,4-dicarboxyphenyl) sulfone dianhydride, as well as units derived from an ether anhydride such as 2,2-bis[4-(3,4-dicarboxyphenoxy)phenyl]propane dianhydride, may be prepared by the reaction of a mixture of said dianhydrides with diamines such as m-phenylene diamine. The polyetherimides have high thermal stability and solvent resistance.
