ABSTRACT:
A process for producing a flame resistant rigid polyurethane foam by reacting a reaction mixture comprising a polyetherpolyol and/or a polyesterpolyol having an active hydrogen atom, a polyisocyanate, water and/or a volatile foaming agent and an emulsifying agent, in which a specific amine compound shown by the general formula as defined hereinafter in the specification is added to the reaction system, the weight ratio of amine compound to polyetherpolyol and/or polyesterpolyol being from 70:30 to 30:70, and also the flame resistant rigid polyurethane foam produced by the process.
