Abstract

Procedure for preparing foams with good fire resistance, based on polymers consisting essentially of recurring motifs of the formula: ** (see formula) ** Which comprise a polyoxazolidone and a carbodiimide chain and in which r and r 'are identical or different, represent an aliphatic, cycloaliphatic or aromatic radical, characterized in that an isocyanate compound and a polyfunctional epoxide compound are reacted in amounts such that the ratio between the number of the isocyanate groupings and the number of the epoxide groupings is at least 1.1: 1, in the presence of a carbodiimide-forming catalyst from isocyanate and of an oxazolidone-forming catalyst from epoxide and from isocyanate.
