  • Patent number: 5886092
    Abstract: Disclosed are methods for preparing carbon-containing materials resistant to alkali metal disruption, and compositions suitable for the preparation of carbon-containing materials resistant to alkali metal disruption. A composition in accordance with the invention comprises a mixture of (a) a binder phase having a viscosity of less than 10 Pascal seconds and a char yield in excess of 20% upon heating to a temperature of 800.degree.-1200.degree. C., and comprising at least one polymerizable resin and (b) particles of a solid material which is thermally stable at a temperature of 800.degree.-1200.degree. C., the particles having a granulometry wherein void spaces between the particles have a size of less than 20 .mu.m in diameter and the particles are coated with a layer of binder phase having a thickness of less than 2 .mu.m. When the composition is carbonized by heating to a temperature of 800.degree.-1200.degree. C., the composition forms a carbon-containing material resistant to alkali metal disruption.

  • Patent number: 5854339
    Abstract: An adhesive composition based on resorcinol novolac or resorcinol-phenolic novolac consisting essentially of 35-75% by weight of novolac, less than 25% by weight of water, and 10-40% by weight of an aliphatic divalent, trivalent or tetravalent alcohol. The adhesive composition may also contain up to 20% by weight of filler, based on the amount of novolac, water and alcohol. In a method for preparing the adhesive composition based on resorcinol novolac or resorcinol-phenolic novolac, the novolac is produced by conventional condensation, whereupon an aliphatic divalent, trivalent or tetravalent alcohol is added and water in the novolac is distilled off, resulting in an adhesive composition as defined above. Alternatively, the amount of water can be reduced in the condensation of the novolac to be replaced with an aliphatic divalent, trivalant or tetravalent alcohol.

  • Patent number: 5777009
    Abstract: A polyestercarbonate copolymer blend which exhibits a glass transition temperature lower than bisphenol-A carbonate homopolymer, shows improved processability and fire-retardancy. The desired lower Tg and improved flow can be achieved by the polycondensation of a dihydric phenol and aliphatic dicarboxylic acid. The condensate is polymerized with a carbonate forming reagent. The resin is fire-retarded with a mixture of halogenated polycarbonate, potassium diphenylsulfone sulfonate and polytetrafluoroethylene.
