CHLORINATED VINYL CHLORIDE RESIN AND ITS PRODUCTION

Title:

CHLORINATED VINYL CHLORIDE RESIN AND ITS PRODUCTION

Document Type and Number:

Japanese Patent JP3487742

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To obtain a CPVC (chlorinated vinyl chloride resin) having excellent gelling performance and heat-resistance and provide its production process.
SOLUTION: This CPVC is produced by chlorinating a PVC (vinyl chloride resin) having the following characteristics. The BET specific surface area of the PVC is 1.3-8 m2/g, the peak ratio (chlorine element peak × 2/carbon element peak) of the 1S bond energy value(eV) of carbon element and chlorine element is >0.6 in the particle surface analysis by ESCA analysis (electron spectroscopy for chemical analysis) and the infrared absorption spectrum of the PVC satisfies the following formula. 1.8 ≥ absorbance ratio D603/D690≥1.1 wherein D603 and D690 are absorbances at 603 cm-1 and 690 cm-1, respectively.
