ABSTRACT:
A method for removing polymer scales adhering to the inner surface of a polymerization vessel, which comprises polymerizing vinyl chloride monomer in an aqueous medium, discharging the resulting vinyl chloride polymer together with the aqueous medium from the polymerization vessel, thereafter placing in the vessel both a reaction product resulting from the reaction of an amine and acrylic acid or its derivative and an organic liquid which can dissolve or swell the polyvinyl polymer, and washing the inner surface of the vessel with the organic liquid solution of the reaction product.
