Procedure

The resin composition of this invention is manufactured by a cooking method in which phenol and formaldehyde are preferrably divided into two desired portions. The first portion of phenol and formaldehyde is reacted in the presence of sodium hydroxide catalyst under high temperature to form the highly condensed and cross-linkable phenol-formaldehyde resin. Then the second portions of phenol, formaldehyde and/or sodium hydroxide are added and reacted at low temperature to form the non-resinous phenol-formaldehyde condensates.
