Abstract
PURPOSE: To facilitate the discharge of a phenolic resin having high viscosity and high softening point from the reactor, by adding a polyhydric alcohol to the resin before discharge, thereby reducing the viscosity and the softening point.
CONSTITUTION: In the preparation of a novolak-type phenolic resin having high viscosity and high softening point, pref. 1W10 wt% of a polyhydric alcohol, e.g. ethylene glycol, low-molecular, liquid polypropylene glycol, pentaerythrytol, etc. is added to the resin before discharging from the reactor. When the amount of the polyhydric alcohol exceeds 10 wt%, the high-temperature rigidity and the curing rate of the resin decreases to undesirable levels, and when it is lower than 1 wt%, the effect is not satisfactory.
