Title:
VINYL CHLORIDE-BASED POLYMER
Document Type and Number:
WIPO Patent Application WO/2011/055867
Kind Code:
A1
Abstract:
The present invention relates to a suspension polymerization method of a vinyl chloride-based polymer. The amount of vinyl chloride monomers injected in the initial stage of polymerization is 50-80% of the total vinyl chloride monomers, and the rest of the vinyl chloride monomers are injected when a polymerization conversion rate is 15-30%, thereby enabling preparation of a vinyl chloride-based polymer having a small amount of fish eye and an excellent initial coloring property with a high polymerization productivity.
