Abstract
Copolyetheresteramide based compositions which are stable with respect to the effects of heat, light and oxygen are disclosed. From about 0.05 to about 5% of 4-4'-bis-(.alpha.-.alpha.'-dimethylbenzyl)-diphenylamide either alone or in combination with 0.01 to 2% of cuprous iodide and potassium iodide such that the ratio of CuI to KI is between 0.1 and 1.9 is added to the copolyetheresteramide to form a stable composition.
