Abstract

Aminoplasts or phenoplasts are made by the continuous condensation of the reactants in the presence of solid ion-exchange resins which are not soluble in the reaction mixture and are fixedly arranged in the reaction space as catalysts. The process of the invention may be applied to the reaction of aldehydes, e.g. formaldehyde, acetaldehyde or furfural with phenols, e.g. phenol per se, cresol, xylenol or resorcinol or amino compounds, e.g. urea or melamine. In the examples, formaldehyde is condensed with (1) phenol using a cation-exchange sulphonated phenol-formaldehyde resin as catalyst to form a novolak; (2) urea using a diphenylol dimethylamine-formaldehyde resin as catalyst; (3) melamine using a catalyst as in (2); (4) cresol, using a two-layer catalyst, the lower layer comprising a polyacrylate resin cross-linked with divinyl benzene, the upper layer comprising a sulphonated polystyrene resin.
