C. in the presence or absence of one or more monohydric, dihydric or trihydric alcohols and an entraining agent, and the water of reaction formed during the etherification is separated off at 45.degree.-120.degree. C., andB. where the process is carried out beginning with the methylolation in a non-polar organic solvent, the methylolation is carried out in the presence of 0.1-0.3% by weight, based on the phenol employed, of Me.sup.++ ions, the etherification is effected at 95.degree.-120.degree. C. in the presence of one or more monohydric, dihydric or trihydric alcohols, with or without recycling of the distillate which passes over, and finally residual phenol in the products prepared by A. or B. is removed by evaporation in a thin film evaporator until the phenol content is less than 1% by weight.The phenol resol ethers prepared according to the invention are useful for the preparation of coating systems and for adhesives.
