Claim 1

IN MAKING A PHENOL-ALDEHYDE CONDENSATE IN WHICH THE PARA POSITION IN THE PHENOLIC PORTION OF THE CONDENSATE IS PREDOMINANTLY IN UNREACTED CONDITION, THE PROCESS WHICH COMPRISES HEATING A MIXTURE OF A PARA-UNSUBSTITUTED PHENOL IN SUBSTANTIALLY ANHYDROUS CONDITION WITH AN INORGANIC ALKALI CATALYST OF CONDENSATION OF PHENOL WITH AN ALDEHYDE AND IN COMMUNICATION WITH THE ATMOSPHERE TO A TEMPERATURE OF AT LEAST 130*C. AND BELOW THE BOILING POINT OF THE PHENOL, THEN INTRODUCING AN AQUEOUS SOLUTION OF FORMALDEHYDE SLOWLY INTO THE PREHEATED MIXTURE IN TOTAL PROPORTION OF 0.1-1 MOLE OF THE FORMALDEHYDE FOR 1 MOLE OF THE PHENOL, AND MAINTAINING THE RESULTING MIXTURE AT ALL TIMES DURING THE INTRODUCTION OF THE FORMALDEHYDE AT A TEMPERATURE WITHIN THE RANGE STATED AND UNTIL ALL OF THE FORMALDEHYDE HAS BEEN INTRODUCED AND SUBSTANTIALLY NO MORE WATER ESCAPES FROM THE MIXTURE AT THE SAID TEMPERATURE.
