Abstract

In a process for the production of an aqueous solution of a thermosetting phenol-formaldehyde resin, after phenol and formaldehyde have been reacted in the presence of a catalyst containing calcium, the pH of the product is adjusted by means of hydrofluoric acid or an ammonium salt thereof, which has been found to avoid the creation of a precipitate.
