Abstract: Preparation of thermally stable, soft polyurethane foam, comprises reacting optionally modified organic polyisocyanates (A) with high molecular weight compounds (B) containing at least two reactive hydrogen atoms and optional low molecular weight chain extenders and/or cross-linking agents (C), in the presence of propellants (D), catalysts (E), flame retardants (F) and optional auxiliary agents and/or additives (G).(B) are mixed condensation reaction products, comprising a mixture of at least two dicarboxylic acid/polyfunctional alcohol pre-condensation reaction products, or at least one dicarboxylic acid/polyfunctional alcohol pre-condensation reaction product and a reagent mixture based upon this product for a condensation polymer, which are subjected to a post-condensation reaction.
