Abstract: The method is effected by the reaction between a modified organic polyisocyanate and at least two reactive hydrogen atoms and optionally with elongators of the chain, in the presence of pore formation agents, catalysts and optionally by standard auxiliary means and/or additives, in a closed press mould in compaction. By the method at least one modified organic polyisocyanate of pure MDI and at least one polyetheralcohol (polyoxyalkylenepolyol) with NCO content less than 15 at. % react together. 6 claims
