Abstract
PURPOSE: To prevent scale deposition on the wall and like areas of a reaction vessel, by applying a specified compound to the wall or like areas, adding a thiocyanate to the polymerization system and polymerizing a vinyl chloride type monomer in the presence of a specified polymerization initiator.
CONSTITUTION: The inner wall and areas with which monomers contact, of a polymerization vessel are coated, in an amount of at least 0.001g/m2, with an aqueous solution obtained by dissolving into water, an alkali metal or ammonium salt of a sulfonic acid type or carboxylic acid type dye and/or an alkali metal or ammonium salt of an organic sulfonic or carboxylic acid containing conjugated double bonds and adjusting the solution to of pH a below 7. The coated solution is then dried. Next, to a vinyl chloride type monomer is added 1W500ppm of a thiocyanate and the mixture is fed to the polymerization vessel and polymerized in an aqueous medium containing a dispersion aid and as a polymerization initiator an oil-soluble peroxide catalyst having a solubility in water at 20°C, of 0.2W10wt%.
