  • [专利] Method for preparing chlorinated polyvinyl chloride resin
    (KR101654147) The present invention relates to a manufacturing method of a chlorinated polyvinyl chloride resin. More particularly, the manufacturing method of a chlorinated polyvinyl chloride resin efficiently removes hydrochloric acid remaining in pores of a chlorinated polyvinyl chloride resin obtained by chlorination process of PVC or PVC-containing copolymer by using a mixture of a percarbonate-based compound, or a carbonate-based compound, and hydrogen peroxide as a counteractive agent. Also, the manufacturing method of a chlorinated polyvinyl chloride resin improves thermal stability, and alleviates color differences in the resin, and color differences during a process.
