ABSTRACT:
Compounds of the formula (I) ##STR1## in which A.sub.1 is e.g. --O-- or >N--R.sub.1 where R.sub.1 is e.g. hydrogen, methyl, 2,2,6,6-tetramethyl-4-piperidyl or 1,2,2,6,6-pentamethyl-4-piperidyl, A.sub.2 is e.g. a direct bond or --CH.sub.2 --, X.sub.1 and X.sub.3 which can be identical or different are e.g. a group of the formula (IIIa) or (IIIb) ##STR2## in which A.sub.3 and A.sub.4 which can be identical or different are e.g. an >N--R.sub.1 group where R.sub.1 is as defined above, R.sub.3 is e.g. --(CH.sub.2).sub.2-6 -- or --(CH.sub.2).sub.3 --O--(CH.sub.2).sub.2-4 --O--(CH.sub.2).sub.3 -- and R.sub.4 is e.g. hydrogen or methyl, X.sub.2 is e.g. 2-hydroxytrimethylene or a group of the formula (IVa) ##STR3## where R.sub.8 is e.g. a group of the formula (V) ##STR4## m is e.g. zero or 1, n is e.g. a number from 1 to 10, Y.sub.1 is e.g. OH, ONa, OK, a group R.sub.8 or a group --X.sub.1 Z or --X.sub.3 Z with Z being e.g. hydrogen or methyl and Y.sub.2 is e.g. hydrogen, methyl or a group ##STR5## with the provisos that (1) X.sub.1 or X.sub.2 or X.sub.3 contains a group of the formula (II), ##STR6## with R.sub.2 being e.g. hydrogen or methyl, that (2) each of the groups A.sub.1, A.sub.2, X.sub.1, X.sub.2, X.sub.3 and m has the same or a different definition in the individual recurring structural units of the formula (I) and that (3) the only definition of Y.sub.1 is the group --X.sub.1 Z, when m is zero and n is 1.
