Beschreibung
Zusammenfassung:	New flexible polyurethane foams (A), obtained from a polyester polyol (I) and an isocyanate monomer (II), have density less than 0.3 g/cm 3>, Shore C hardness 52 or more and tearing resistance (ASTM D 624 (C)) 10 kg or more. An independent claim is included for the preparation of a polyurethane foam (A'), obtained from (I) and (II) and containing a particulate inorganic filler (III), including a stage of forming a dispersion of (III) in (I), (A') being formed by reacting the dispersion with (II) in presence of a catalyst and a foaming agent.
