Abstract

PURPOSE: To prepare the title resins capable of giving laminates having a small dimensional shrinkage under heating, improved impact resistance, and capable of being punched at low temperatures, by reacting a para - or ortho-substituted alkylphenol with an aldehyde to form a reaction mixture, which is then reacted with a reaction product of phenol or cresol and tung oil.
