ABSTRACT OF THE DISCLOSURE: In the polymerization of vinyl chloride, the adhesion of the resulting polymer to the walls can be prevented by previously applying a specific chemical to the inner walls of the polymerization tank and parts of the device to be contacted with the monomer during the polymerization. This specific chemical is a copoly- condensate obtained by reacting a resol type phenol/ formaldehyde precondensate with a nitrogen-containing compound selected from the group consisting of nitro- phenols, nitrobenzoic noids, nitrobenzenesulfonic acids, aminophenols, aminobenzoic acids and aminobenzenesulfonic acids.
