    摘要: The present invention refers to isocyanate-reactive compositions containing hindered phenolic antioxidants having a molecular weight of at least 700. These compositions, when used to prepare flexible polyurethane foams, especially slabstock foam, provide foams which exhibit a significant reduction of scorch.

    摘要: A prepolymer or elastomer is the reaction product of reactants (a) at least one polyester polyol or fatty acid derived polyol which is the reaction product of at least one initiator and a mixture of fatty acids or derivatives of fatty acids comprising at least about 45 weight percent monounsaturated fatty acids or derivatives thereof, (b) optionally, at least one polyol which is different from the polyol of (a); and (c) at least one isocyanate compound (herein after isocyanate) having an average of at least about 1.8 isocyanate groups per molecule. A process comprises admixing reactants (a) at least one polyol composition comprising the fatty acid derived polyol which is the reaction product of at least one initiator and a mixture of fatty acids or derivatives of fatty acids comprising at least about any of 45 weight percent monounsaturated fatty acids or derivatives thereof; and (b) at least one isocyanate having an average functionality of at least about 1.8 under reaction conditions to form a reaction product which is an elastomer or prepolymer is formed therefrom. An article, coating or thermoplastic polyurethane comprises the elastomer is formed from the prepolymer of or using the process of the invention.
