ABSTRACT:
Polymers, most preferably mono-olefin polymers, are stabilized by the mixture of an ultraviolet light stabilizer and a thiophosphite of the formula ##EQU1## where n is 0 or an integer, R is a divalent aromatic, aliphatic or cycloaliphatic group and R.sub.1 is hydrocarbyl or halohydrocarbyl. Less preferably, there can be used compounds of the formula ##EQU2## where R.sub.1 and R are as defined above and R.sub.2 is aryl or haloaryl.
