For this reason, attempts have been made to improve the stability of vinyl chloride resins by using metal compounds as main stabilizers and using various other stabilizing aids in combination.
• Some of the above-mentioned stabilizing aids have a problem in that they have poor compatibility with a vinyl chloride-based resin and the physical properties such as transparency of the obtained molded article are deteriorated. Further, if the dispersibility of the stabilizing aid is poor, there is also a problem that a sharp black decomposition (zinc baling) on spots occurs in the obtained molded article.
