METHOD OF PREPARING DISPERSION AND METHOD OF MANUFACTURING POLYVINYL CHLORIDE PASTE RESIN

摘要

PROBLEM TO BE SOLVED: To provide a method of preparing a dispersion composed of an aqueous solution of a surfactant and vinyl chloride monomer which realizes a space saving and a reduced cost by simplifying facilities and to provide a method of polymerization in which the dispersion is added during a microsuspension polymerization. SOLUTION: The dispersion composed of the vinyl chloride monomer and the aqueous solution of the surfactant is prepared easily by using a static mixer and the dispersion is added to a polymerization liquid intermittently or continuously while a polymerization reaction is in progress.
