Abstract
The present invention concerns a polycyanurate foam with a structural element A and either terminal amino groups and/or at least one of the following structural elements 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 either spontaneously or thermally or catalytically induced. The water/alcohol reacts with free cyanate groups under cleavage of CO. The resulting amino groups can react further in the polymerization.
