Abstract
PURPOSE: To prevent the deposition of vinyl chloride polymer to the inner wall of a polymerization apparatus, etc. without lowering the physical properties of the product, by coating the parts contacting with the monomer, with a condensate of a phenol compound and an aldehyde.
CONSTITUTION: An aqueous solution of a resol-type condensate of a phenol compound, e.g. carbolic acid, etc., with formaldehyde, is coated on the inner wall of a polymerization apparatus for vinyl chloride monomer or the parts contacting with the monomer during the polymerization, to give the coating amount of pref. 0.005W 10g/m2. The coating is applied prior to the initiation of each polymerization batch, or at intervals of several batches where the walls are rinsed with water.
EFFECT: Deposition of the polymer to the wall surface, etc. is suppressed and the deposited polymer can be easily removed by rinsing.
