Abstract

PURPOSE: To obtain titled resin colored only slightly and having almost no fluctuation of the hue, by providing as a material, a mixture having a lowered viscosity, prepared by mixing nonylphenol with phenol in a specific ratio, feeding the mixture to a reaction kettle without heating the mixture, and reacting the mixture with an aldehyde.
CONSTITUTION: Phenol component (A) is obtained by mixing (i) 80W30wt% nonylphenol with (ii) 20W70wt% phenol. The modified phenol resin is obtained by feeding the phenol component (A), without heating, to a reaction kettle and reacting the mixture with (B) an aldehyde component such as formaldehyde and, if necessary, (C) a drying oil such as tung oil, in the presence of an acid catalyst such as oxalic acid or a basic catalyst such as barium hydroxide.
USE: Preparation of laminated sheets.
