Procedure

A mixture composed of 170 parts of p-phenylphenol, 22.5 parts of 80% paraformaldehyde, 1.7 parts of p-toluenesulfonic acid, and 200 parts of toluene was heated at 100° C. for 2 hours. The reaction product was freed of toluene and water by distillation under reduced pressure. Thus there was obtained 172 parts of light brown p-phenylphenol-formaldehyde-resin having a softening point of 85° C.
