Abstract
Compounds having the formula ##SPC1##
Wherein R1 and R2 are independently the same or different alkyl groups of 1 to 8 carbon atoms, cycloalkyl of 5 to 6 carbon atoms or one of R1 and R2 is hydrogen, R3 is hydrogen or lower alkyl of 1 to 6 carbon atoms, R4 is hydrogen or a group ##SPC2##
m is 1 to 6, n is 0 to 2 and x is 1 to 2 are good thermal and oxidative stabilizers for synthetic polymers.
