ABSTRACT:
O-Alkenyl substituted hydroxylamines of formula I ##STR1## where R.sub.1 and R.sub.2 are independently hydrogen, alkyl, alkenyl, aryl or phenylalkyl, and R.sub.3 to R.sub.7 are independently hydrogen, alkyl or substituted alkyl are very effective process stabilizers for polymeric systems providing melt flow stabilization and resistance to discoloration during processing at elevated temperatures as well as effective stabilizers for lubricant compositions.
