Abstract
The present invention provides a polyurethane which has excellent flame retardance and various excellent performances. A phosphoramidate compound having a specific structure is used as a flame retardant for a polyurethane foam or a polyurethane elastomer. By mixing this flame retardant with a raw material of a polyurethane resin (polyol, polyisocyanate and various additives), a polyurethane reactive raw material composition is obtained. By reacting the polyisocyanate and active hydrogen-containing compounds such as polyol in the polyurethane reactive raw material composition, a curing reaction takes place and a polyurethane foam composition or polyurethane elastomer composition is obtained. The obtained polyurethane resin composition has excellent flame retardance and other excellent performances as the polyurethane foam or polyurethane elastomer.
