Title:
STABILIZING AGENT FOR CHLORINE-CONTAINING POLYMER, AND CHLORINE-CONTAINING POLYMER COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2008/087784
Kind Code:
A1
Abstract:
Disclosed is a stabilizing agent for a chlorine-containing polymer, which comprises (A) an epoxy-containing acrylic resin having an epoxy equivalent of not smaller than 100 and less than 250 and (B) an aminocrotonic acid ester in an amount of 0.5 to 70 parts by weight based on 100 parts by weight of the epoxy-containing acrylic resin as the main components and further comprises (C) a polyhydric alcohol in an amount of 0.5 to 70 parts by weight or (D) hindered amine or phenylindole in an amount of 0.1 to 70 parts by weight, both based on 100 parts by weight of the epoxy-containing acrylic resin as an auxiliary component. The stabilizing agent contains no metal, and therefore has no adverse influence on the environment, has a high effect of preventing the initial coloring, has high heat resistance or sustained heat resistance, and can prevent the coloration of a vinyl chloride resin effectively when the vinyl chloride resin is maintained at a high temperature for a long term.
