ABSTRACT:
Composition containing an organic polymer, with the exception of epoxy-based polymers, a lubricant, a metal-working fluid or a hydraulic fluid and, as stabilizer, at least one dioxaphosphorinane compound of the formulae ##STR1## wherein R.sub.1 to R.sub.6, R' and R" are independently hydrogen, alkyl, alkenyl, cycloalkyl or aryl, X.sup.+ is hydrogen, a metal cation or quaternary nitrogen atom, A is a n-valent hydrocarbyl moiety, n is 1 to 4, and m is 1 or 2.
These compositions are stabilized against thermal, oxidative and/or actinic degradation. The abovementioned compounds are also very suitable as wear-resistant agents and high-pressure additives in lubricants.
Some of the dioxaphosphorinane compounds are novel.
