Stabilizer for chlorine-containing polymers, process for the preparation thereof and chlorine-containing polymer composition

摘要

A stabilizer for chlorine-containing polymers comprises a fat or oil-saponified product/silicate composite in the form of hydrophobic particles comprising: siliceous compound particles comprising amorphous or low-crystalline silicate of a metal of Group II, IV or V of the periodic table; higher fatty acid salt of a metal of Group II, IV or V in the pores or on the surface of said siliceous compound; and glycerin or a derivative thereof; process for the preparation of the stabilizer and chlorine-containing polymer compositions comprising the stabilizer.
