A stabilizer system for organic polymers is formed nby a phenolic antioxidizer and by a zinc or aluminum ncompound selected among carboxylates, dithiocarbamates, nphenates, organometallic complexes of zinc or of aluminnum, or zinc oxide, in an amount of from 50 to 10,000 ppm, nas expressed as metal zinc or aluminum, relatively to the nphenolic antioxidizer. n The stabilized polymer compositions comprise an norganic polymer and a stabilizing amount of said stabilizner system. n The compound of zinc or aluminum, used in the indincated amounts, allows the stabilizer effect exerted by nthe phenolic antioxidizer on the organic polymers to be nimproved. |
