실험 절차

A resorcinol/diglycidyl ether of bisphenol A addition product was prepared in a 3-liter reactor equipped with an agitator, thermometer and reflux condenser. The reactor was charged with about 330.3 g. resorcinol, 1500 ml. toluene and 3.0 g. triphenylphosphine. The stirred charge was heated to reflux at about 112° C. and about 654.0 g. diglycidyl ether of bisphenol A (Ciba-Geigy Araldite GY 6004) was added dropwise in about 2.5 hours. The charge was refluxed for about one hour, devolatilized at reduced pressure and about 36.0 g. amorphous silica was added to obtain a light tan resorcinol ether compound (RE4) having a 77° C. softening point, and having a 0.45 wt. % residual oxirane oxygen.
