Abstract
Precondensates of urea and formaldehyde containing monomethylolacrylamidomethyleneurea are produced from pure acrylamidomethyleneurea and urea/formaldehyde precondensate or from the starting substances used for the manufacture of acrylamidomethyleneurea with formaldehyde. They are useful additives for aminoplastic resins, which in turn may be used as glue in the manufacture of chipboard sheets.
