Use of N,N-dialkylhydroxylamines and their preparation Abstract of the Disclosure The compounds of the formula (I) Image (I) wherein R1 and R2 are independently alkyl of 8 to 36 carbon atoms, are useful for stabilizing a poly(arylene sulfide) resin, a modified poly- styrene or a polymer containing a diene component against thermal, oxidative or actinic degradation. N,N-Dialkylhydroxylamines of the formula (I) can be prepared by an improved process involving a reverse Michael reaction of the N-oxides of the corresponding .beta.-dialkylaminopropionic esters, amides or nitriles or of .beta.-dialkylaminosuccinyl esters or imides. N,N-Dialkylhydroxylamines of the formula (I) can also be prepared by animproved process involving the direct oxidation of the corresponding N,N-dialkylamines with aqueous hydrogen peroxide in a lower alkanol solvent.
