Abstract

PURPOSE: A butadiene oilgomer of less than 500 average molecular weight is used as a modifier of resol type phenolic resin, thus producing said modified phenolic resin capable of giving laminates with high impact strength.
CONSTITUTION: A resol type phenolic resin is obtained by reaction of a phenol as phenol, cresol, xylenol and an aldehyde as formaldehyde or acetaldehyde in the presence of an alkaline catalyst as tertiary amine to form a resol type resin. During of after the production of the resin, 5W10g., per mole of phenol, of a butadiene oligomer of 500 or less molecular weight of 5W100g. per mole of phenol, of an adduct from a butadiene oligomer of 500 or less average molecular weight and a phenol are added to the resol type phenolic resin to produce said resin.
