Abstract (en)
[origin: WO9532238A1] The present invention relates to a process for the preparation of polyurethane foams by reaction of at least one polyisocyanate, optionally in the presence of an expansion agent, with a composition obtained by reaction in an anhydrous medium of a polyurethane foam with a polyether polyol, having a molecular weight comprised between 2000 and 8000, the quality of foam being comprised between 10 and 40 % by weight with respect to the mass of polyether polyol and of polyurethane foam.
