Abstract

Procedure for stabilizing a synthetic organic polymer, normally subject to deterioration by ultraviolet light, characterized by combining with it from 0.01 to 2% by weight of the polymer of a stabilizing compound of the formula ** formula ** in which R1 and R2 are the same or different alkyl group, containing 1 to 12 carbon atoms, or together with the carbon atoms to which they are attached form a monocyclic ring system having 5 to 12 carbon atoms, is an integer from 1 to 3 which n is 1, R3 is an alkyl group of 1 to 20 carbon atoms or a benzyl group, when n is 2, R3 is an alkylene group of 1 to 20 carbon atoms, a p-xylenyl group or an alkyl-substituted p-xylylenic group.
