  • Patent number: 5152939
    Abstract: A method for forming carbon-carbon composites consists of impregnating structures with carbon-forming precursor compounds comprising multi-functional benzoxazine compounds. The impregnated structures are pyrolyzed to form carbonaceous char which serves to fill the interstices in the structure, thus densifying the composites. The process of impregnation and pyrolysis is repeated as many times as required to obtain the composite density desired. Unusually high char yields are produced by multi-functional benzoxazine compounds in which benzoxazine are joined to each other through a bridge characterized by having conjugated unsaturation associated therewith. A number of preferred compounds providing unexpectedly high yields of char are shown, enabling the desired densification to be achieved with a minimum number of impregnation and pyrolysis cycles, thereby reducing the costs of forming the composites.

These resoles are of low viscosity, are essentially free of unbound water and volatile organic compounds. They are curable to phenolic formaldehyde resinous solids and are particularly suitable for use in liquid injection molding processes to form composites.

  • Patent number: 4564466
    Abstract: Method for the manufacture of a polymer with triaromatic methane units as basic building blocks, the electric conductivity of which is obtained through the formation of charge transfer complexes. Electron donors and/or electron acceptors are added to the synthetic polymer during or after its preparation, for forming charge transfer complexes.

  • Patent number: 4507428
    Abstract: An aqueous dispersion comprising a poly(3,4-dihydro-3-substituted-1,3 benzoxazine) and a protonated reactive polyamine, wherein the polyamine is at least difunctional, its reactive groups being primary or secondary amine and is protonated with an inorganic or organic acid and wherein the poly(dihydrobenzoxazine) is the reaction product of about 1 equivalent of a primary amine, about 1 equivalent of a phenol and about two equivalents of formaldehyde. The dispersions can be dried and cured to provide useful surface coatings and primers. The curing step occurs without evolution of volatile matter.

  • Patent number: 4468507
    Abstract: Large-scale preparation of branched novolacs by the acid catalyzed, exothermic condensation of methylol-reactive phenols with polymethylol diphenols is made practical by first carrying out the reaction on a scale which permits temperature control simply by cooling and then separately adding more of the premixed reactants and the catalyst at rates such that the temperature of the reaction mixture can readily be controlled.

  • Patent number: 4454298
    Abstract: A granular or powdery resin which is a condensation product of a phenol and an aldehyde and optionally a nitrogen-containing compound having at least two active hydrogens, said granular or powdery resin being characterized by(A) containing spherical primary particles and secondary particles resulting from the agglomeration of the primary particles, each of said particles having a particle diameter of 0.1 to 150 microns,(B) having such a size that at least 50% by weight thereof can pass through a 100 Tyler mesh sieve,(C) having a free phenol content, determined by liquid chromatography, of not more than 500 ppm, and(D) having a methanol solubility (S) of more than 20% by weight when about 10 g of the resin is heated under reflux in 500 ml of substantially anhydrous methanol.

  • Patent number: 4431783
    Abstract: Polymerization of vinyl chloride in aqueous suspension using a polymerization reactor having adherently deposited on internal surfaces thereof a build-up suppressant coating comprising a product of build-up suppressant activity formable by (and preferably formed by) the condensation of an effective 1-naphthol (preferably 1-naphthol itself) and formaldehyde. The condensation is preferably effected in a base-catalyzed reaction; it may also (less preferably) be effected in an acid-catalyzed reaction. The coating product itself and a process for its production are also claimed.
