  • Patent number: 4843106
    Abstract: Fluid polymer polyol dispersions which impart improved fire resistance to polyurethane foam. The fluid polymer polyol dispersions are prepared by grafting one or more monomers onto a polyol backbone with the difference that the grafting takes place in the presence of a flame retardant. During the grafting process the flame retardant is incorporated into the fluid polymer polyol dispersion. When such fluid polymer polyol dispersions are used, the fire resistance of the final polyurethane foam is improved relative to cases where a conventional fluid polymer polyol dispersion and a flame retardant are added separately to the polyurethane foam formulation.

In the first stage, an organic polyisocyanate is reacted with an organic compound containing at least two epoxide groups (NCO: epoxide equivalent ratio of 1.2:1 to 500:1) in the presence of a tertiary amine catalyst. This reaction is stopped when no more than 65% of the isocyanate groups have reacted by adding an alkylating sulfonic acid alkyl ester of methyl iodide and/or of dimethyl sulfate in an amount equivalent to the amount of tertiary amine catalyst present. A latent catalyst capable of being activated by heat is subsequently added to the intermediate product and the resultant mixture is heated in a mold to complete the crosslinking of the intermediate product and to form the molded article.

  • Patent number: 4621104
    Abstract: Liquid bromine-containing alkoxylation products of butyne-(1,4)-diol which are storage stable are produced. More specifically, 1.5 to 2.5 mols alkylene oxide are reacted with each mol of butyne-(1,4)-diol present at elevated temperature in the presence of a catalyst. The catalyst is selected from (1) thioethers having a molecular weight of up to 5000 obtained by adding a mercaptan and/or mercaptoalcohol to an unsaturated hydrocarbon and/or (2) thioethers other than those of (1) having a molecular weight of from 500 to 5000 and/or (3) alkali metal chlorides. This alkoxylation product is then reacted with bromine at -10.degree. to 80.degree. C. The bromide is reoxidized with aqueous hydrogen peroxide solution, stabilized with a relatively non-volatile epoxide and dehydrated. The product thus obtained is particularly useful in the production of flame resistant isocyanate addition products such as polyurethane foams.

  • Patent number: 4616043
    Abstract: A light stable, fast reacting, aliphatic polyurethane sprayable coating composition and injectable open molding material is prepared by reacting an A side composition comprising a trimerized or biuret polymethylene polyisocyanate prepolymer with a B side composition comprising an admixture of an alkoxy polyalkylene glycol, such as methoxypolyethylene glycol and an aromatic polyamine such as a diethyl toluene diamine to provide a polyurethane reaction product which rapidly gels, may be quickly removed from the mold, has good green strength and high temperature resistance and is characterized by good ultraviolet or light stability properties. Optionally, the B side composition may contain a catalytic amount of a metal carboxylate like lead napthenate. The A and B side compositions may be sprayed onto a mat in an open mold and also may be sprayed in conjunction with chopped glass fibers, to form a glass-fiber spray coating.
