ABSTRACT:
A stabilized halogen-containing resin composition contains 100 parts by weight of a halogenated polymer of an ethylenically unsaturated monomer, 0.01 to 5 parts by weight of at least one member selected from a perchloric acid-containing hydrotalcite compound and perchloric acid salt, and 0.01 to 10 parts by weight of a hydrotalcite compound prepared by removing crystal water therefrom under heat. The stabilized, halogen-containing resin composition is excellent in heat stability and gives molded articles free from deterioration in color tone.
