PURPOSE:To improve the flexibility, impact resistance, crack resistance and dimensional stability of a phenol resin, by modifying it with a glycidyl compd. CONSTITUTION:When the numbers of moles of phenol, formaldehyde and a glycidyl compd. are represented by P, F and G, respectively, they are mixed with a compounding quantity which satisfies G/P=0.001-5.8F/¦P-G¦ are reacted at 95-125 deg.C for about 60-600min to obtain a solid phenol resin modified with the glycidyl compd.
