    摘要： Stable graft polymer dispersions are prepared employing in situ free radical polymerization of ethylenically unsaturated monomer or monomers in an amine-terminated polyoxyalkylene polyether polymer. These dispersions are useful in the preparation of polyurethane foams which have improved tensile strength, elongation, load deflection and tear strength properties.

    摘要： Liquid oxyalkylated polyol prepolymers are prepared by oxyalkylating a prepolymer prepared from a hydroxy aromatic compound, an aldehyde and furfuryl alcohol with an alkylene oxide containing about 2-4 carbon atoms. The oxyalkylated polyol prepolymers have a viscosity of 1000-500,000 centipoises at 25.degree. C. and contain about 1.1-6 moles of interpolymerized aldehyde, about 3.1-15 moles of interpolymerized furfuryl alcohol, and about 1-10 moles of interpolymerized alkylene oxide for each mole of interpolymerized hydroxy aromatic compound. The resultant prepolymers are highly reactive and may be further polymerized with or without monomers such as polyisocyanate to produce flame retardant solid or cellular interpolymers. Flame retardant solid or cellular polyurethanes are prepared in one variant by interpolymerizing organic polyisocyanates with the oxyalkylated polyol prepolymers. In another variant, flame retardant closed cell cellular interpolymers are provided. Processes are provided for preparing the aforementioned novel oxyalkylated polyol prepolymers and solid or cellular interpolymers.

    摘要： Cellular foam compositions are prepared by catalytically condensing an organic polyisocyanate in the presence of a blowing agent, from 0.01 to 0.5 equivalent per equivalent of isocyanate of a primary hydroxy-terminated polyoxyalkylene or polyester polyol and a catalyst system comprising (a) methanol, (b) a tertiary amine trimerization catalyst, and (c) a urethane catalyst. The resulting foam compositions are characterized by carbodiimide, isocyanurate and urethane linkages and exhibit unexpectedly low friability, improved strength properties, and good flame retardancy.

    摘要： Liquid prepolymers are prepared by interpolymerizing monomers including a hydroxy aromatic compound, an aldehyde and furfuryl alcohol. The resultant liquid prepolymers have a viscosity of about 100-500,000 centipoises at 25.degree. C. and contain about 1.1-6 moles of interpolymerized aldehyde and about 3.1-15 moles of interpolymerized furfuryl alcohol for each mole of interpolymerized hydroxy aromatic compound. The prepolymers are highly reactive and may be polymerized with or without other monomers to produce flame retardant solid or cellular interpolymers. In one variant, flame retardant solid or cellular polymers are produced by interpolymerizing organic polyisocyanates with the prepolymers. In another variant, solid or cellular interpolymers are produced by polymerizing the prepolymers without monomers such as polyisocyanate in the presence of unreacted furfuryl alcohol. Processes are provided for preparing the aforementioned novel liquid prepolymers and solid or cellular interpolymers.
