Bicyclo(3.3.1)nonane derivatives and use in stabilizing organic materials
 Bicyclo[3.3.1]nonane derivatives of the general formula (I) ##STR1## where n is an integer from 1 to 70, PA1 R.sup.1 is hydrogen, PA1 R.sup.2 is hydrogen or hydroxyl, or the radical ##STR2## R.sup.3 and R.sup.4 are each independently of the other phenyl or 1- or 2-naphthyl, which phenyl or naphthyl may each be substituted by 1, 2 or 3 C.sub.1 -C.sub.12 -alkyls, C.sub.1 -C.sub.12 -alkoxys, chlorines, bromines, fluorines, trifluoromethyls or cyanos, in the case of 2 or 3 substituents these substituents being identical or different, PA1 A and B are each independently of the other a chemical bond, C.sub.1 -C.sub.22 -alkylene, cycloalkylene ##STR3## where m and o are each from 1 to 20 and PA2 R.sup.10 is hydrogen, C.sub.1 -C.sub.22 -alkyl, C.sub.5 -C.sub.12 -cycloalkyl, C.sub.7 -C.sub.18 -phenylalkyl, phenyl or C.sub.2 -C.sub.22 -cyanoalkyl, PA1 M is a radical of the formula ##STR4## which may be bonded to A not only via the nitrogen atom but also via the carbon atom, and PA1 R.sup.11, R.sup.12, R.sup.13 and R.sup.14 are each independently of the others C.sub.1 -C.sub.4 -alkyl, or PA1 R.sup.11 and R.sup.12 and/or R.sup.13 and R.sup.14 are each together tetramethylene or pentamethylene, PA1 R.sup.5 is hydrogen, cyano, hydroxyl, ##STR5## R.sup.15 is hydrogen, C.sub.1 -C.sub.22 -alkyl, C.sub.5 -C.sub.12 -cycloalkyl, C.sub.5 -C.sub.16 -phenylalkyl or a 5- or 6-membered heterocycle, or, when n is 1, --M--B--R.sup.5 is a radical of the formula ##STR6## where R.sup.16 is C.sub.1 -C.sub.4 -alkyl, PA1 R.sub.17 is hydrogen, C.sub.1 -C.sub.4 -alkyl or C.sub.1 -C.sub.4 -alkoxy and PA1 R.sub.18 is hydrogen or C.sub.1 -C.sub.12 -alkyl, have remarkably good stabilizing properties in respect of plastics, are colorless, are highly compatible with organic polymers and are stable to thermal decomposition.
