- R.sub.3 is hydrogen, alkyl of 1 to 20 carbon atoms, phenylalkyl of 7 to 15 carbon atoms or aryl of 6 to 10 carbon atoms;
- R.sub.4, R.sub.5 and R.sub.6 are independently hydrogen, alkyl of 1 to 4 carbon atoms or aryl of 6 to 10 carbon atoms;
- X and Y are independently --O--, --S-- or --NR.sub.16 -- where R.sub.16 is hydrogen, alkyl of 1 to 20 carbon atoms, cycloalkyl of 5 to 12 carbon atoms, alkenyl of 3 to 18 carbon atoms, aryl of 6 to 10 carbon atoms, said aryl substituted by one or two alkyl of 1 to 4 carbon atoms; or phenylalkyl of 7 to 15 carbon atoms;
- W and Z are independently O or S; and
- n, m, o and p are independently zero or 1.
- 2. The compound according to claim 1 which is
- 1-isobutyl-2,8-di(1-methoxy-2,2,6,6-tetramethylpiperidin-4-yloxy)-3,7,9-trioxa-1-aza-2,8-diphosphaspiro[4.5]decane.
