Title:
METHOD FOR PREPARING VINYL CHLORIDE-BASED POLYMER, AND DEVICE FOR PREPARING VINYL CHLORIDE-BASED POLYMER
Document Type and Number:
WIPO Patent Application WO/2018/044017
Kind Code:
A1
Abstract:
The present invention relates to a method for preparing a vinyl chloride-based polymer, which can prepare a vinyl chloride-based polymer having excellent surface properties by adjusting the level of foam generated during a polymerization reaction to an adequate level, to a vinyl chloride-based polymer prepared thereby, and to a device for preparing a vinyl chloride-based polymer, which can prepare the vinyl chloride-based polymer. Accordingly, the method for preparing a vinyl chloride-based polymer implements the polymerization reaction while maintaining the level of the foam, generated during the polymerization reaction, at an adequate level and can thereby prepare a vinyl chloride-based polymer having excellent surface properties, meaning, for instance, fewer fish eyes, and having excellent transparency.
