    摘要: A catalyst selected from a perfluorosulfonic acid and an anhydride thereof enables a non-conjugated drying oil to react with a phenol to form a phenol-added vegetable oil without causing hydrolysis of the non-conjugated drying oil. The phenol-added vegetable oil is allowed to react with an aldehyde to form a vegetable oil-modified phenolic resin. A laminate produced by impregnating paper with the vegetable oil-modified phenolic resin and laminating and molding the impregnated paper is excellent in low temperature punching quality and electrical properties and is free from low molecular weight components oozing out the surface of the laminate.
