Abstract

PURPOSE: To prepare a heat resistant phenolic resin by adding a viscosity depressant to the reaction mixture prior to the heat dehydration to lower the viscosity of the phenolic resin, whereby the stirring during the dehydration process and the discharge of the phenolic resin from the reaction vessel are facilitated.
