Abstract
Benzoyloxybenzoates having the formula ##SPC1## Wherein R.sup.1 , r.sup.2 and R.sup.3 are lower alkyl or cycloalkyl, R.sup.4 is hydrogen, lower alkyl or cycloalkyl, R.sup.5 is alkylene or oxyalkylene having up to 18 carbon atoms, and m is an integer from 2 to 4, are useful as stabilizers of organic materials such as polyolefins.
