Claim 1

A compound of the general formula (I) ##STR15## wherein n is an integer from 1 to 100, X 1 and X 2 are either identical and represent a bond or ##STR16## in which n is 1, are different, in which case X 2 then has no meaning, R 1 is, if A is a group of formula (Va), hydrogen, C 1 to C 30 alkyl, phenyl or otherwise a group of the formula (IIa) or (IIb) ##STR17## in which formulae Y is a radical ##STR18## which occupies the ring positions 3;4, B is methylene, R 4 denotes hydrogen or methyl, R 5 and R 6 are identical or different and denote hydrogen, C 1 to C 18 alkyl, phenyl which is unsubstituted or substituted by chlorine or C 1 to C 4 alkyl, or C 7 to C 14 aralkyl which is unsubstituted or substituted by C 1 to C 4 alkyl, or, together with the carbon atom linking these radicals, form a C 5 to C 12 cycloalkyl ring which is unsubstituted or substituted by up to four C 1 to C 4 alkyl groups, or form a piperidine ring which is unsubstituted or substituted by up to four C 1 - to C 4 -alkyl groups, R 7 denotes a hydrogen atom or a C 1 to C 4 alkyl group and R 2 is, if R 1 denotes a group of formula (IIb) and A denotes a bonding or A is a group of formula (Va), hydrogen or C 1 to C 30 alkyl or phenyl, or otherwise a group of the formulae (II), or hydrogen in case of A=--CH 2 O--, or a ##STR19## group which is substituted by C 1 to C 18 alkyl, C 5 or C 6 cycloalkyl or phenyl and which has ##STR20## linked to A, or C 2 to C 18 alkylene, or phenylene which is unsubstituted or substituted by up to two C 1 to C 4 alkyl groups, or C 7 to C 14 aralkylene or α,ω-dicarboxy-C 1 to-C 8 alkylene or a dicarboxy-C 6 ring or a radical>N-alkyl having 1 to 6 C atoms or a group of the formula (III) ##STR21## in which R 5 and R 6 have the meanings indicated above, or an isocyanuric acid radical or a nitrogen atom or a ##STR22## radical, R 3 represents hydrogen if X 1 , X 2 and E have no meaning, or, if X 2 and E have no meaning, represents C 1 to C 18 alkyl or phenyl, which is unsubstituted or substituted by chlorine, hydroxyl, amino or C 1 to C 4 alkyl, C 7 to C 14 aralkyl or C 5 or C 6 cycloalkyl or denotes C 2 to C 12 alkylene or phenylene which is unsubstituted or substituted by one to four C 1 to C 4 alkyl groups, or denotes C 7 to C 14 aralkylene, A represents a bond or --CH 2 -- or --OCH 2 -- having --O-- linked to R 2 , or a group of the formula (IV) ##STR23## in which Q represents a radical (IIa) or (IIb), B 1 is a bond or --O-- and R 8 has the same meaning as R 2 , free valences being saturated by the group ##STR24## or A represents a group of the formula (Va) ##STR25## in which R 4 , R 5 , R 6 and Y have the meanings indicated above, Z is a bond or --CH(OH)-- and R 9 represents an OH group and has the meanings of R 1 , and m is 0 or 1, in oligomeric or polymeric products in which n>1 R 2 , as a terminal group, is hydrogen, R 3 is a bifunctional or trifunctional radical, from the group indicated for R 3 and A has the meaning of a bifunctional radical from the group indicated for A, and E is a group of the formula R 2 --A--CH(R 1 )-O-wherein R 1 , R 2 and A have the meanings indicated above, or E has no meaning, and at least in formula I one of the radicals R 1 , R 2 or A contains a diazaspiradecane system of the formulae (II) or (V), or E is a terminal group which can be a lower alkyl ester, --NCO or halogen.
