Abstract

PURPOSE: To prepare phenolic resin giving a laminated sheet having excellent electrical insulating properties and punchability, etc., by reacting a polybutadiene-maleic anhydride resin with a phenolic compound and formaldehyde.
CONSTITUTION: (A) 100pts.wt. of a polybutadiene-maleic anhydride resin prepared by the addition reaction of (a) 100pts.wt. of a polybutadiene (number average molecular weight 200W5,000) with (b) 1W50pts.wt. of maleic anhydride, is reacted with (B) 50W400pts.wt. of a phenolic compound (e.g. phenol, etc.) in the presence of an acid catalyst (e.g. benzene-sulfonic acid, etc.). The product is reacted with (c) formaldehyde (0.8W2.5mol on the basis of 1mol of the phenol) in the presence of a basic catalyst (e.g. trimethylamine) to give a new resol-type phenolic resin. The preferable amount of the acid catalyst is 0.001W20wt% on the basis of the sum of the polybutadiene and the phenolic compound.
