ABSTRACT Title "Polyamide Compositions" The high temperature aging of polyamides is substantially improved by incorporating therein an anti- oxidant and an oxide of a metal of Group II or III of the Periodic Table, preferably a synthetic zeolite. The total amount of antioxidant and metal oxide is at least 1%, preferably 1 to 5%, and the amount of metal oxide is prefer- ably 0.5 to 5%, Polyamides which can be stabilized in this way include Nylon-6*, Nylon-11* and Nylon-12*. * Trade Mark
