ABSTRACT:
It is an object of the invention to provide a ketone-modified resorcinol-formalin resin, which has a moderate flowability when transformed into an aqueous solution and has both a reduced content of resorcinol monomer and a reduced content of resorcinol-formalin resin of resorcinol pentanuclear or higher nuclear bodies. The invention relates to a ketone-modified resorcinol-formalin resin, which is produced by a two-step reaction and wherein a peak area corresponding resorcinol monomer is 3 to 9% and a peak area corresponding to resorcinol pentanuclear and higher nuclear bodies is 30 to 55% relative to the total peak area obtained by gel permeation chromatographic analysis of the resorcinol-formalin resin.
