ABSTRACT:
The new compounds of formula (I) ##STR1## in which R.sub.1 is e.g. hydrogen or methyl, R.sub.2 is e.g. a group --OR.sub.5 or ##STR2## in which R.sub.5 is e.g. 2,2,6,6-tetramethyl-4-piperidyl or 1,2,2,6,6-pentamethyl-4-piperidyl, R.sub.6 and R.sub.7 which are identical or different are e.g. C.sub.1 -C.sub.8 alkyl, tetrahydrofurfuryl, 2,2,6,6-tetramethyl-4-piperidyl or 1,2,2,6,6-pentamethyl-4-piperidyl, or R.sub.6 is also hydrogen, or the group ##STR3## is e.g. 4-morpholinyl, R.sub.3 and R.sub.4 which are identical or different are e.g. hydrogen, methyl, 2,2,6,6-tetramethyl-4-piperidyl or 1,2,2,6,6-pentamethyl-4-piperidyl, m and n are e.g. 3, and X is e.g. --O-- or ##STR4## where R.sub.9 is C.sub.1 -C.sub.8 alkyl, tetrahydrofurfuryl, 2,2,6,6-tetramethyl-4-piperidyl or 1,2,2,6,6-pentamethyl-4-piperidyl, are effective as light stabilizer, heat stabilizers and oxidation stabilizers for organic materials, in particular synthetic polymers.
