Abstract
"Procedure for the manufacture of phenolic resins", mainly aimed at obtaining foams, from a phenol-formaldehyde mixture by condensation in at least two successive phases in the presence of an alkaline catalyst, characterized in that after having made phenol -formaldehyde on commissioning, after condensation and cooling the reaction medium at the end of the last phase of this condensation, a sufficient amount of acid is incorporated into said medium to obtain a pH between 3.0 and 4.0, approximately, preferably between 3.4 and 3.6, and the resinous phase is separated from the aqueous medium in view of its subsequent use.
