ABSTRACT:
Process for the preparation of modified phenolic resins in which the starting components used for preparation of these modified phenolic resins are subjected to a condensation reaction under pressure and in the presence of an inert organic solvent which forms an azeotrope with water, and in which the water is removed from the reaction mixture continuously by azeotropic distillation. An improved space/time yield is achieved by this pressure distillation.
