Beschreibung
Zusammenfassung:	A solid and water-insoluble condensation product of N,N'-ethyleneurea with formaldehyde, having the structure:wherein n is an integer from 20 to 60 with a mean value of 41, and having an average number molecular weight Mn ranging from 2000 to 6000.Such a product, when added to a polymer in combination with an ammonium phosphate, permits the production of articles having good resistance to heat and to thermo-oxidation.
