    摘要： A process for producing sulfur foam containing at least 50 weight percent sulfur, which comprises: (a) reacting molten sulfur with an organic protonic acid which is reactive with molten sulfur so as to incorporate the organic acid with sulfur to form a sulfur-organic acid adduct containing protonic acid groups; (b) mixing an organic surfactant agent with the adduct to obtain a mixture of adduct and surfactant agent; and then (c) reacting the mixture with a polyisocyanate to obtain sulfur foam.

    摘要： Process for preparing multicellular products which comprises mixing urea and/or a urea derivative, and an acid with a monomeric mixture comprising 60-95 percent by weight of acrylonitrile and 40-5 percent by weight of a vinyl monomer copolymerizable with acrylonitrile, polymerizing the mixture with the use of catalyst and/or by irradiation, and thereafter heating the resulting polymer at 100*-250* C.; and multicellular products produced by the above process, in which fine cells having an average diameter of less than 1.0 mm are substantially uniformly dispersed in the polymer and which product has a specific gravity of less than 0.3 g/cm3.

    摘要： NONCOMBUSTIBLE AND FIREPROOFING POLYMER COMPOSITIONS ARE PREPARED BY REACTING VIA A CONDENSATION MECHANISM, A POLYCOL, AN ORGANIC ANHYDRIDE, OR AN ORGANIC ACID, AND BORIC ACID TO FORM FIRST AN ESTERIFIED MATERIAL AND THEN FURTHER CONDENSING THIS ESTERIFIED MATERIAL WITH BOTH A NITROGENOUS SPUMIFIC COMPOUND AND A CARBOHYDRATE CLASS COMPOUND TO FORM THE NONCOMBUSTIBLE AND FIREPROOFING POLYMER COMPOSITIONS. THE POLYMER COMPOSITIONS MAY THEN BE FORMED INTO NONCOMBUSTIBLE FILMS, SHEETS, LAMINATES OR FIBERS, CAST, EXTRUDED OR OTHERWISE FORMED INTO ARTICLES OR MAY BE INCORPORATED INTO PAINTS, LACQUERS, VARNISHES, PLASTICS, RUBBERS, TO YIELD THESE MATERIALS FIREPROOF, AND ADDITIONALLY MAY BE COATED ALONE OR AS A FURTHER COMPOSITION ON FIBERS, FABRICS, WOOD, PAPER, CARDBOARD, PLASTICS, LEATHER, WIRE AND SO ON.

    摘要： Sulfur-based foams produced by reacting aromatic carbocyclic or heterocyclic compound substituted by -OH, or -NHR groups with molten sulfur to form an aromatic polysulfide, cross-linking the product, generating CO2 or COS in situ before cross-linking is complete, and cooling the foamed product to ambient temperature. In a preferred embodiment the product of the aromatic carbocyclic compound and sulfur is modified with certain carboxy, sulfonic, phosphonic, phosphinic, boronic or borinic acids and crosslinking and CO2 generation is accomplished by addition of a polyisocyanate. Additional sulfur and liquid organic polysulfides may be incorporated in the foams.
