실험 절차

Into a 500 ml flask are charged resorcinol (110 g, 1.0 mol) and 37% formalin (44.5 g), and the mixture is reacted at 70° C. for 5 hours. After the reaction, water is distilled off at 150° C. under reduced pressure (inner pressure: 25 mmHg) to give a resorcinol/formaldehyde resin having a softening point of 98° C. (Resin X).
