Patent number: 5278209Abstract: Only two symmetrical stabilizers in a polyolefin or copolymer thereof, provide thermooxidative ("TO") or antioxidative ("AO") stability. One is an arylphosphite or arylfluorophosphite; the other is a monomolecular tri-substituted triazine in which each of three chlorine atoms on a trihalo-s-triazine is substituted with a piperazinone in which the N atom in the 4-position is alkylated.

The trace amount of phosphite has a surprising booster effect, giving the stabilized composition excellent TO stability. Articles thermoformed from the stabilized polyolefin or copolymer thereof may be used under the hood or the dash of a vehicle, and, in containers for packaging goods, all of which articles are subject to TO degradation even if they are not subject to ultraviolet light degradation.Type: GrantFiled: May 26, 1992Date of Patent: January 11, 1994Inventors: George Kletecka, John T.
