1 results about "Vinylchloride polymer" patented technology

To provide: a method for preparing a vinyl chloride-based polymer that can have excellent balance between the CPA and the bulk density of the vinyl chloride-based polymer while reducing the content of an unreacted monomer remaining in a final product; and a vinyl chloride-based polymer prepared by the preparation method.SOLUTION: The present invention relates to: a method for enabling preparation of a vinyl chloride-based polymer showing improved melting rate and mechanical properties and low harmfulness, by pre-mixing and injecting a mixed dispersant comprising polyvinyl alcohol of high hydration and a carbonate metal salt before polymerization, and then polymerizing a vinyl chloride-based monomer; and a vinyl chloride-based polymer prepared by the method.SELECTED DRAWING: None
