Abstract | The present invention concerns a polycyanurate foam comprising the structura l element A and either terminal amino groups and/or at least one of the following structural elements B, C, or D: (see formulas A, B, C or D) wherein the foam has closed pores that contain carbon dioxide. This foam can be produced in that a substance is worked into the starting material for the polycyanurate that releases water or alcohol approximately at the start of polymerization spontaneously or thermally or catalytically induced. The water/alcohol reacts with free cyanate groups under cleavage of CO2. The resulting amino groups can react further in the polymerization. |
