More Information
Summary:A stabilizer system for organic polymers is formed by a phenolic antioxidizer and by a zinc or aluminum compound selected among carboxylates, dithiocarbamates, phenates, organometallic complexes of zinc or of aluminum, or zinc oxide, in an amount of from 50 to 10,000 ppm, as expressed as metal zinc or aluminum, relatively to the phenolic antioxidizer. The stabilized polymer compositions comprise an organic polymer and a stabilizing amount of said stabilizer system. The compound of zinc or aluminum, used in the indicated amounts, allows the stabilizer effect exerted by the phenolic antioxidizer on the organic polymers to be improved.
