Abstract
PURPOSE: To prevent the deposition of vinyl chloride polymer to the polymerizer or to prevent the contamination of the product with the polymer peeled off from the polymerizer, by applying arginic acid or its salt to the inner walls of the polymerizer or to the part of the polymerizer which may come into contact with the monomer during the polymerization process.
CONSTITUTION: In the polymerization of vinyl chloride or the copolymerization of vinyl chloride with copolymerizable monomers in an aqueous medium or in bulk, the inner walls of the polymerizer and the part which come into contact with the monomer are coated with arginic acid or its salt. The concentration of arginic acid is 0.01W20 wt%, pref. 0.05W5 wt% for the efficient application, and its coating amount is pref. 0.005W10 g/m2. It can be applied by brushing spraying, etc.
