Title:
CHLORINATED VINYL CHLORIDE RESIN COMPOSITION AND CHLORINATED VINYL CHLORIDE RESIN MOLDED BODY
Document Type and Number:
WIPO Patent Application WO/2022/210365
Kind Code:
A1
Abstract:
The present invention provides: a chlorinated vinyl chloride resin composition which enables the production of a molded body that exhibits excellently low volatility during molding as well as excellent processability, thermal stability and heat resistance after molding, while having high surface smoothness; and a chlorinated vinyl chloride resin molded body. The present invention provides a chlorinated vinyl chloride resin composition which contains a chlorinated vinyl chloride resin, a chlorinated polyethylene and a thermal stabilizer, wherein: the chlorinated vinyl chloride resin has a vinylidene unit content of 3% by mass to 32% by mass; the mass ratio of the content of the chlorinated polyethylene to the content of the thermal stabilizer ((chlorinated polyethylene)/(thermal stabilizer)) is from 1.0 to 7.0; and the heating loss at 200°C is less than 3% by mass.
