Abstract

PURPOSE: A heat-stable PVC resin composition which is protected from discoloration which otherwise occurs during high-temperature processing, by adding a carbonate or oxide of Ca, Ba or Mg in mixing a PVC resin with a lead stabilizer and a thioether stabilizer.
CONSTITUTION: In mixing (A) a PVC resin with (B) a lead stabilizer and (C) a thioether stabilizer for the purpose of controlling decomposition of the PVC resin, (D) a carbonate or oxide of Ca, Be or Mg is added. Thereby, discoloration of the resin at high temperatures is avoided. Examples of (B) include lead stearate and white lead, and examples of (C) include dilauryl thiodipropionate and 4,4'-thiobis (3-methyl-6-tert-butylphenol). With respect to the amount of (D), at least 0.5pt.wt. of (D) is necessary to 1pt.wt. of (C) and 1W10pts.wt. of (D) is preferred.
