STABILIZED POLYMER COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a thermal stabilization means of a halogen-containing polymer composition having rather small dangerousness against health and environment and having cost merit. SOLUTION: A stabilized halogen-containing polymer composition includes: (a) a halogenated polymer substance in a content more than 40 wt.%; (b) 0.01-5.0 phr of a methyl tin stabilizer comprising a mixture of a dimethyl tin stabilizer and a monomethyl tin stabilizer in a content higher than 25 wt.% of the methyl tin stabilizer; and (c) 0.01-5 phr of a salt of a polyacid substance for forming the stabilized halogen-containing polymer composition.
