Claims
- 1. As stabilizer for halogen-containing polymers, a metal salt selected from the group consisting of metal salts of the polymeric and monomeric reaction products of an alpha olefin and maleic anhydride, said polymeric metal salt having recurring units of the formula: ##STR17##and said metal monomeric salt being represented by the formula: ##STR18## or mixtures thereof wherein M represents a di- or tetravalent metal selected from the group consisting of calcium, zinc, cadmium, barium and tin; n is 1 or 2 in formulas (C) and (F) and 2 or 4 in formulas (A), (B), (D), and (E); R is selected from the group consisting of hydrogen, aryl, alkyl, aralkyl, alkaryl and substituted derivatives thereof having 1 to 17 carbon atoms which can be halogenated, and R' is selected from the group consisting of alkali metal cations, ammonium cation, lower alkyl-substituted ammonium cations, hydrogen atom, aryl groups, alkyl groups, aralkyl groups, alkaryl groups and substituted derivatives of said groups having 1 to 17 carbon atoms which can be halogenated.
- 2. The composition of claim 1 wherein M is zinc.
- 3. The composition of claim 2 wherein R is n-C.sub.14 H.sub.29.
- 4. The composition of claim 1 wherein M is calcium.
- 5. The composition of claim 4 wherein R is n-C.sub.14 H.sub.29.
- 6. The composition of claim 5 wherein R' is ammonium.
- 7. The composition of claim 5 wherein R' is sodium.
- 8. The composition of claim 3 wherein the structure of the salt corresponds essentially to formula (F).
- 9. The composition of claim 5 wherein the structure of the salt corresponds essentially to formula (F).
