    摘要: The invention relates to the use of poly-N,N-di-(hydroxyalkyl)-polycarbonamides of aliphatic or cycloaliphatic polycarboxylic acids as reactive flame-retardants for polyurethane foams, and in particular polyurethane integral skin foams and polyurethane rigid foams which are produced with the aid of organic blowing agents. These reactive flame-retardants are added in quantities of from 11.5 to 50 parts by weight, and most preferably from 12 to 25 parts by weight, based on 100 parts of the relatively high molecular weight polyol used for the preparation of the foam. The integral skin or rigid foams produced are flame-resistant and because of their reduced flammability are capable of passing various regulation fire tests, and in particular those testing foams for use in vehicles for transport.

    摘要: Polyurethanes which have been prepared or combined with another material are made by combining or applying a polyurethane-forming reaction mixture or polyurethane to another material such as a PVC foil or textile. The polyurethane-forming mixture or polyurethane is made up of an organic polyisocyanate, a high molecular weight isocyanate reactive material, a catalyst and a stabilizer against thermolysis and contact discoloration. The required stabilizer is an epoxide having an epoxide equivalent weight between 57 and 10,000. Other additives commonly used in polyurethane chemistry such as blowing agents, chain extenders and surfactants may also be employed. The polyurethane composites thus produced are characterized by improved thermal stability and reduced discoloration.

The invention also relates to dispersions or suspensions of mono- to tetrapolyhydroxyalkyl monoureas corresponding to the above formula in relatively high molecular weight compounds containing terminal hydroxyl, primary or secondary amino, carboxyl or hydrazide groups. Preferred are relatively high molecular weight polyols, having a molecular weight in the range from 400 to 10,000. The content of polyhydroxyalkyl monoureas amounts to between 3 and 50% by weight. Finally, the invention relates to tris-hydroxyalkyl monoureas corresponding to the above formula in which n=2, n'=1 and the sum of n+n'=3.
