Abstract
The present invention comprises a stabilized halogen containing polymer, preferably poly(vinyl halide), and more preferably poly(vinyl chloride) composition. A preferred polymer composition is a rigid halogenated polymer such as rigid poly(vinyl chloride). The composition contains at least one metal salt selected from the group consisting of at least one carboxylic acid or derivative thereof having at least two carboxyl groups, at least one carboxyl group and at least one hydroxyl group, at least one carboxyl group and at least one mercaptan, and an aromatic carboxylic acid having at least one carboxyl group. The metal salt is most preferably disodium adipate.
