Title:
METHOD FOR PRODUCING CHLORINATED VINYL CHLORIDE RESIN
Document Type and Number:
WIPO Patent Application WO/2017/145864
Kind Code:
A1
Abstract:
The present invention relates to a method for producing a chlorinated vinyl chloride resin, in which a chlorination reaction is carried out by bringing a chlorine gas into contact with a vinyl chloride resin powder, while having the chlorine gas and the vinyl chloride resin powder irradiated with ultraviolet light, and wherein one or more inorganic fillers selected from the group consisting of silica, carbon black and talc are mixed into the vinyl chloride resin powder. Consequently, the present invention provides a method for producing a chlorinated vinyl chloride resin, which exhibits improved productivity when a chlorination reaction is carried out by bringing a chlorine gas into contact with a vinyl chloride resin powder, while having the chlorine gas and the vinyl chloride resin powder irradiated with ultraviolet light.
