Abstract
An allyletherificated phenol aralkyl resin is obtained through the reaction of a phenol aralkyl resin with an allyl halide in the presence of a base in an organic solvent at room temperature to 100.degree. C. and changed into an allylated phenol aralkyl resin at 160.degree.-250.degree. C. through Claisen rearrangement. The two resins are low in melt viscosity. Epoxy resin compositions containing the allylated phenol aralkyl resin as the curing agent give cured products being excellent in heat and moisture resistances.
