METHOD FOR PREPARING VINYL CHLORIDE-BASED POLYMER AND VINYL CHLORIDE-BASED POLYMER PREPARED THEREBY

Document Type and Number:

WIPO Patent Application WO/2023/277530

Kind Code:

A1

Abstract:

The present invention relates to a method capable of preparing a vinyl chloride-based polymer exhibiting improved melting rates and mechanical properties and having low harmfulness by pre-mixing and adding a carbonate metal salt and a mixing dispersant containing highly hydrated polyvinyl alcohol before polymerization and then polymerizing vinyl chloride-based monomers, and to a vinyl chloride-based polymer prepared by the method.
