Vulcanizable or vulcanized diene elastomers containing stabilizing amounts of 6-oxy-2,2,4-trialkyl-1, 2-dihydroquinoline derivatives of the formula
wherein the R1's are lower alkyl radicals, R is a straight or branched chain radical having the formula CnH2n+2-x where n is an integer from one to ten and x is an integer from two to four, show resistance to ozone attack. The 6-oxy-2,2,4- trialkyl-1, 2-dihydroquinoline derivatives themselves are novel compounds.
