Abstract
A polymeric composition containing more than 5% halogen can be improved in heat and light stability by the incorporation therein of small amounts of a novel stabilizer which is the metallic salt of the reaction product of an alpha-olefin with maleic anhydride. The stabilizers of the invention can be used either alone or in combination with conventional stabilizers for halogen containing polymeric materials.
