Title:
CHLORINATED VINYL CHLORIDE RESIN
Document Type and Number:
WIPO Patent Application WO/2020/203858
Kind Code:
A1
Abstract:
The present invention provides a chlorinated vinyl chloride resin that makes it possible to produce a molded product having excellent moldability and easy softening property and also excellent gloss while having high heat resistance and mechanical strength. The present invention provides a chlorinated vinyl chloride resin in which a component ratio [C150 component/(A150 component + B150 component + C150 component)] of a C150 component, which is obtained by waveform separating a free induction decay curve of 1H spin-spin relaxation that is measured by a Solid Echo method at 150°C using pulsed NMR into three curves derived from the three components of A150 component, B150 component and C150 component in the order of shorter relaxation time by the least-squares method, is 8.0-30.0% (inclusive).
