ABSTRACT:
Thermoplastic compositions are stabilized with a phosphite of the formula: ##STR1## wherein Y.sup.1 is an alkyl and Y.sup.2 is selected from tert-butyl and sec-butyl. The phosphite is particularly effective for thermoplastics irradiated with high energy gamma-radiation. Irradiated articles made with the phosphite stabilized thermoplastic compositions exhibit improved discoloration resistance compared to various other phosphite stabilized thermoplastic compositions.
