<P>PROBLEM TO BE SOLVED: To provide a polyurethane foam improved in flame retardancy, mechanical physical properties and moisture resistance. <P>SOLUTION: The method for producing a polyurethane foam includes reacting an active hydrogen component (A) and a polyisocyanate component (B) in the presence of a foaming agent (C) and a catalyst (D), in which (A) contains an amide compound (E) represented by general formula (I) and/or an imide compound having a specific structure. [In general formula (I), R<SB POS="POST">1</SB>represents hydrocarbon group or the like, R<SB POS="POST">2</SB>and R<SB POS="POST">3</SB>each independently represents a hydrocarbon group or the like, and X<SB POS="POST">1</SB>represents oxygen atom or sulfur atom]. <P>COPYRIGHT: (C)2013,JPO&INPIT |
