Abstract

PURPOSE: To prepare a water-soluble phenolic resin which can be easily dried after impregnation, by reacting a phenol with an aldehyde in the presence of an alkaline catalyst, adding a specific oligomer to the reaction system.
CONSTITUTION: The title resin having an average molecular weight of 220W240 is prepared by reacting a phenol with an aldehyde in the presence of an alkaline catalyst adding 5.0W15.0 g, based on 1 mole of the phenol, of a nonylphenol-formaldehyde oligomer (having 2W4 nuclei) to the reaction system. The oligomer may be added to the reaction mixture before the reaction, or to the reaction product having the above molecular weitht.
