Procedure

which process comprises reacting an aqueous mixture of phenol and formaldehyde containing a mol ratio of formaldehyde to phenol between 1.7 and 2.8 and a pH-active material in an amount producing a pH between 5.8 and 8.5, at least until a phenol-formaldehyde polymer is formed as signified by the appearance of a hydrophobe point upon water dilution;

Workup

  1. customa pH-active material in an amount producing a pH between 5.8 and 8.5
