Abstract

PURPOSE: To polymerize vinyl chloride, preventing the deposition of the polymer to the wall of the polymerization apparatus, without lowering the physical properties of the polymer and the polymerization rate, by using a polymerization apparatus wherein the inner walls etc. are coated with a specific polymer, and adding a compound forming a hydrophilic coating film by the polymerization to the reaction system.
CONSTITUTION: (A) A condensate of (a) a precondensate of phenol with an aldehyde, with (b) a polyhydric phenol, e.g. catechol, resorcinol, hydroquinone, pyrogallol, phloroglucinol, etc., is applied to the inner walls of a polymerization apparatus and the parts contacting with the monomers during polymerization. (B) Vinyl chloride or a monomer copolymerizable therewith and (C) a polar organic compound which reacts with the component (A) on the wall of the liquid part of the apparatus and forms a hydrophilic coating film having a contact angle of ≤2° with water (e.g. alcohols, organic acids, esters, etc.) are fed to the apparatus, and the mixture is subjected to the aqueous suspension polymerization. The preferable amount of (C) is 0.001W1wt% on the basis of the amount of (B).
