Abstract

The invention relates to a process for preparing a water-soluble adhesive by condensing phenol formaldehyde in an alkaline medium. Phenolic residues, resulting from the preparation of phenol by the cumene process, are used as raw materials. Said phenolic residues are added phenol, sodium hydroxide and anhydrous sodium sulphate and are subjected to the condensation with a formaldehyde solution having a concentration of 35%, at a temperature of 100°C for 20...60 minutes.
