Abstract: The method is effected by the reaction between a modifiedorganic polyisocyanate and at least two reactive hydrogen atomsand optionally with elongators of the chain, in the presence ofpore formation agents, catalysts and optionally by standardauxiliary means and/or additives, in a closed press mould incompaction. By the method at least one modified organicpolyisocyanate of pure MDI and at least one polyetheralcohol(polyoxyalkylenepolyol) with NCO content less than 15 at. % reacttogether.6 claims
