Abstract
PURPOSE: To prevent the deposition of a polymer on an inner wall of a polymerizer, by a method wherein the inner wall of the polymerizer is coated with a co-condensate resulting from the reaction of a nitrogen-contg. cpd. with precondensate of a phenol and an aldehyde, and the polymn. of vinyl chloride is carried out in the polymerizer.
CONSTITUTION: In the production of a homopolymer of vinyl chloride or a copolymer of vinyl chloride and a monomer copolymerizable therewith in an aq. medium or by a bulk polymn., the inner wall of a polymerizer and parts with which the monomer is contacted during polymn. are previously coated with a co-condensate resulting from the reaction of a precondensate of a phenol and an aldehyde with a nitrogen-contg. cpd. selected from nitrophenol, nitrobenzoic acid, nitrobenzene- sulfonic acid, aminophenol, aminobenzoic acid and aminobenzenesulfonic acid. An example of the phenol-aldehyde precondensate used is a resol type phenol-formaldehyde precondensate obtd. by using a basic catalyst.
