ABSTRACT:
A polyolefin composition is provided which is resistant to gas fading upon exposure to atmospheric pollutants. The compositions containing a stabilizing amount of a phosphite of the formula ##STR1## wherein Y.sup.1 is an alkyl, preferably t-butyl, and Y.sup.2 is t-butyl or sec-butyl. Fibers and films made from the composition exhibit improved fade resistance compared to fibers and films made from polyolefins stabilized with various other commercially available phosphite. The compositions also contain an additive selected from hindered phenolic antioxidants and hindered amine light stabilizers.
