Abstract: This invention relates to flame-retarded cross-linked elastomer compositions obtained from an elastomeric polyurethane prepolymer; an organic fire-retardant additive containing chlorine and/or bromine; a compound of antimony; and a hexaalkoxymethyl melamine. These new compositions are self-extinguishing as well as non-dripping.

Abstract: Disclosed are N-substituted triorganostannylhydrocarbylcarboxylic acid hydrazides useful as insecticides.

Abstract: Thermoplastic polyurethanes prepared from a reaction mixture comprising:(a) a poly(oxypropylene)-poly(oxyethylene) glycol of molecular weight from 1000 to about 3000 containing 25-60% by weight oxyethylene groups;(b) a polyester polyol of molecular weight from 1000 to about 3000;(c) a polyisocyanate; and(d) a low molecular weight polyol chain extender.The elastomers are useful in automotive product applications, cattle ear tags, coatings and coated fabrics.

Abstract: N-(1,1-dioxotetrahydro-3-thienyl)-2,6-dialkylmorpholines, useful as catalysts in making polyurethane foam.

Abstract: Chain extended polyurethanes are prepared, using certain 3-(hydroxyhydrocarbylsecondaryamino)thiophene 1,1-dioxides, some of which are new chemicals. E.g., 3-(2-hydroxypropylamino)tetrahydrothiophene 1,1-dioxide is especially useful as a chain extender for high resiliency, flexible polyurethane foams.

Abstract: Flexible automobile exterior body parts are molded from a polyurethane elastomer prepared from a reaction mixture comprising:A. a poly(oxypropylene)-poly(oxyethylene) glycol of molecular weight of from about 1500 to about 4000 containing 15 to 50% by weight oxyethylene groups;B. a "graft" polyol of molecular weight from about 2500 to about 4500, prepared by the in situ polymerization of one or more ethylenically unsaturated monomers in a poly(oxypropylene) and/or poly(oxypropylene)-poly(oxyethylene) glycol containing less than 15% by weight oxyethylene groups;C. methylenebis(4-phenylisocyanate);D. 1,4-butanediol.The invention also relates to this polyurethane elastomer.
