Document Type and Number:
WIPO Patent Application WO/2020/203840
Kind Code:
A1
Abstract:
The present invention provides a chlorinated vinyl-chloride-based resin which has an excellent efficiency of continuous molding and which can combine moldability with molded-article evenness. In a Raman imaging analysis by Raman spectroscopy, the chlorinated vinyl-chloride-based resin of the present invention has an average peak ratio A/B of 0.50-2.00, the A being the intensity of a peak observed in the range of 660-700 cm-1 and the B being the intensity of a peak observed in the range of 600-650 cm-1, the standard deviation of the ratio A/B being 0.090 or less.
