Abstract

Process for preparing synthetic phenol-formaldehyde resins, characterized in that a compound selected from the group consists of phenol, one or more cresols and mixtures thereof, together with at least one compound of general formula ** (see formula) ** Wherein r, which is preferably in the para position, is selected from the group consisting of a phenyl, alkylphenyl group preferably having a maximum of 20 carbon atoms and a group of the general formula: ** (see formula) ** Wherein r'and r "are individually hydrogen, or alkylphenyl, hydroxyphenyl or alkyl groups, preferably having not more than 15 carbon atoms together, are reacted with formaldehyde in the presence of an alkaline catalyst.
