Abstract

Process for obtaining resoles passing through a condensate suitable for storage, characterized in that phenol and aldehyde are mixed in the molar ratio of 1: 1.1-3, one part of the phenol can be replaced by another reactive compound with respect to to the aldehyde, the mixture is condensed with an alkali in aqueous solution to form a pre-condensate having a viscosity of 10 to 25 seconds, measured in a 4 mm din beaker at 20º c, and a solids content of 48%, and this pre-condensate is further condensed after storage for a time of any desired duration, optionally after subsequently adding substances used, to form the desired final product.
