METHOD FOR PREPARING VINYL CHLORIDE-BASED RESIN

摘要

Provided are: a method for preparing vinyl chloride-based resin, comprising preparing slurry through suspension polymerization by mixing a monomer; an oil soluble initiator; a dispersant; and an additive including an emulsifier, a water-soluble initiator or a combination thereof, wherein the monomer includes vinyl chloride, an unsaturated carboxylic acid-based compound and an ethylenic unsaturated compound which can be copolymerized therewith, and the emulsifier includes an anionic emulsifier, a non-ionic emulsifier or a combination thereof.
