Title:
CHLORINATED VINYL CHLORIDE RESIN
Document Type and Number:
WIPO Patent Application WO/2021/201042
Kind Code:
A1
Abstract:
The present invention provides: a chlorinated vinyl chloride resin capable of producing molded objects which, even when used under high pressure, retain high bonding strength and which are less apt to cause troubles such as cracks attributable to a strength deficiency; a molding resin composition including the chlorinated vinyl chloride resin; and a molded object. When this chlorinated vinyl chloride resin is analyzed by the solid-echo method at 30°C using a pulse NMR to obtain a free induction decay curve regarding 1H spin-spin relaxation and the curve is subjected to waveform separation by the least squares method to obtain two curves assigned to two components, A30 component and B30 component in increasing order of relaxation time, then the thus-obtained relaxation time TB of the B30 component and the relaxation time T5B of the B30 component after 5-minute heating at 200°C satisfy that the ratio therebetween, T5B/TB, is 76% or higher but less than 96%.
