  • Alkanediyl bromo-substituted arylenediyl carbonate polymers
    Patent number: 4489189
    Abstract: Carbonate polymer contains both divalent aromatic groups substituted by at least two bromo groups and at least one divalent aliphatic group. The presence of the divalent aliphatic group or groups reduces the melting range of the carbonate polymer. The carbonate polymer is fire resistant and may be admixed with flammable polymer to provide a composition having greater fire resistance than that of the flammable polymer.

  • High voltage insulating compositions containing phosphorus compounds
    Patent number: 4223071
    Abstract: New high voltage insulating compositions are disclosed. The compositions comprise a polymer (e.g. a polysiloxane, epoxide resin or a polymer of one or more olefins or substituted olefins), an antitracking additive (e.g. an alumina hydrate), and certain phosphorus-containing compounds which have been found to provide the compositions with greatly improved resistance to erosion by high voltage stress. The phosphorus-containing compounds include phosphonates, phosphates, phosphites, phosphinates, phosphonites, phosphinites, phosphine oxides and sulfides, and phosphines, and salts and complexes thereof. The phosphorus-containing compound can react in situ with the polymer or other ingredients of the composition.

  • Flame retardant graft polymer compositions prepared from phosphinyl-substituted acrylonitriles
    Patent number: 3985831
    Abstract: Flame retardant graft polymers are prepared by graft polymerizing a phosphinyl-substituted acrylonitrile and at least one other vinyl monomer copolymerizable therewith in the presence of a rubber substrate. Polymers containing greater than 0.6% by weight, preferably 0.8 to 12.0% by weight, phosphorus exhibit flame retardant characteristics, which may be further improved by compounding with bis-halophenoxyalkanes.
