  • Patent number: 5019599
    Abstract: A deodorizing urethane foam comprising a urethane foam substrate and a deodorizing component. The deodorizing component is composed of (A) a Diels-Alder reaction-type addition reaction product between an alpha,beta-unsaturated dicarboxylic anhydride and an olefin or a derivative of the reaction product and optionally (B) a copper compound. This urethane foam is produced by foaming a mixture of materials for the urethane foam substrate and the Diels-Alder reaction-type addition reaction product between an alpha,beta-unsaturated dicarboxylic anhydride and an olefin or its derivative of the reaction product and optionally the copper compound.
