    Abstract: PURPOSE:To impart extremely excellent electrical conductivity to a polyurethane foam having nitrile group, easily, without using particular post-treatment process, by treating the polyurethane foam in a bath containing a specific reducing agent and a specific sulfur compound. CONSTITUTION:A polyurethane foam having nitrile group is treated in a bath containing (A) cupric ion, (B) a reducing agent capable of reducing cupric ion to cuprous ion, and (C) a compound capable of releasing sulfur atom and/or sulfur ion. The polyurethane foam used in the above process is prepared either by dispersing polyacrylonitrile powder in a polyol, or by reacting a polyisocyanate with a polyether polyol containing >=15wt% ethylene oxide based on the whole composition, and dispersing polyacrylonitrile powder in the resultant urethane prepolymer in the presence of water.

    Abstract: PURPOSE: To obtain a latex composition of an very light ultra-low repulsive elastic open cell foam offering a standard characteristic by adjusting a stylene portion contained in a polymer to a specified percentage through a polymerization process or a blending.
    CONSTITUTION: The stylene portion contained in a polymer is adjusted to 53W 73% through a polymerization process or a blending to obtain a high stylene- containing stylene-butadiene copolymer latex. Filler components are selected, for example, from among calcium carbonate, magnesium carbonate, gypsum and titanium oxide at the rate of 10W300pts.wt. per 100pts.wt. in solid form of the high stylene-containing stylene-butadiene copolymer latex. This latex composition thus obtained also contains a plasticizer at the rate of 5W80pts.wt. per 100pts.wt. in solid form of said high stylene-containing stylene-butadiene copolymer latex.

    Abstract: PURPOSE:The titled foam which does not produce distortion cracks when burned and has markedly improved fire and heat resistance, prepared by impregnating or coating a phenolic resin foam with a phosphorus-containing compound and a specified compound. CONSTITUTION:A fire-resistant phenolic resin foam prepared by impregnating or coating a phenolic resin foam with at least one phosphorus-containing compound (e.g., trichloroethyl phosphate, ammonium polyphosphate, or calcium phosphate) and at least one member selected from the group consisting of compounds containing silicon, boron, or aluminum (e.g., clay, calcium silicate, boric acid (anhydride), borax, alumina, or aluminum hydroxide).
