ABSTRACT:
A method for the manufacture of an aminoformaldehyde resin. An amino compound is reacted with formaldehyde or paraformaldehyde in the liquid phase the latter being ensured by the presence of a reactive modifier in the reaction mixture. The reactive modifier comprises an amino-formaldehyde resin which is capable of reaction with further monomers and capable of rendering the mixture of reactants liquid at least at the temperature at which the reaction is to be carried out.
