Abstract 1. A THERMOPLASTIC COMPOSITION OF AN OLEFIN HOMOPOLYMER OR COPOLYMER WHICH CONTAINS AS PRODEGRADANT A FREE CARBOXYLIC ACID AND A METAL SALT OF A CARBOXYLIC ACID SAID METAL HAVING AN ATOMIC NUMBER OF 22 TO 29 AND IN WHICH THE FREE CARBOXYLIC ACID AND THE CARBOXYLIC ACID OF THE METAL CARBOXYLATE ARE BOTH SELECTED FROM THE GROUP R.COOH WHERE R IS A HYDROCARBON GROUP WITH UP TO 30 CARBON ATOMS, EACH BEING PRESENT IN SUCH A CONCENTRATION THAT: (A) THE TOTAL AMOUNT OF METAL SALT+FREE CARBOXYLIC ACID IS BETWEEN 0.001% AND 40% BY WEIGHT BASED ON THE TOTAL COMPOSITION; (B) THE AMOUNT OF FREE CARBOXYLIC ACID IS FROM 10% UP TO 95% BY WEIGHT OF THE TOTAL AMOUNT OF METAL SALT PLUS FREE CARBOXYLIC ACID.
