  Deep curable polymers having heterocyclic ring systems such as isoindoloquinazolinedione ring systems prepared from novel cyanoimide polymers, most desirably 2'-cyanoimide polymers. Preferably the cyanoimide polymers are prepared from a diamine having at least one nitrile group in the two position to an amine group and a dianhydride having at least two cyclic anhydride groups. Copolymers may be prepared having other linkages, notably imide linkages, in addition to isoindoloquinazolinedione ring systems and/or other similar heterocyclic ring systems. The copolymers can be prepared by use of diamines containing one or more cyanoimide groupings and/or imide groups in their structure.

  具有杂环环系统的深度可治愈聚合物，例如从新型氰酰亚胺聚合物制备的异吲哚喹唑啉二酮环系统，最理想的是2'-氰酰亚胺聚合物。优选地，氰酰亚胺聚合物是由具有至少一个腈基在二位到胺基的二胺和具有至少两个环状酸酐基团的二酸酐制备的。可以制备共聚物，其中除了异吲哚喹唑啉二酮环系统和/或其他类似的杂环环系统之外，还具有其他键合，尤其是亚酰亚胺键合。可以通过使用含有一个或多个氰酰亚胺基团和/或亚酰亚胺基团的二胺来制备共聚物。

  The present invention relates to a composition, which comprises a) an organic material susceptible to oxidative, thermal or light-induced degradation, which is a polymer, an oligohydroxy compound, a wax, a fat or a mineral oil, with the proviso that the polymer is not a polypeptide, agar-agar or a component of agar-agar and the oligohydroxy compound is not glucose or a component of agar-agar; and b) a compound of formula (I) n is 1, 2, 3 or 4; when n is 1, R 5 is H, C 1 -C 30 -alkyl, C 3 -C 10 -cycloalkyl, C 6 -C 10 -aryl, which is unsubstituted or substituted by C 1 -C 8 -alkyl, C 1 -C 8 -alkoxy, halogen or one phenyl, C 7 -C 13 -aralkyl, C 2 -C 22 -alkenyl, C 3 -C 12 -alkinyl, OH, C 1 -C 30 -alkyloxy, C 3 -C 10 -cycloalkyloxy, C 6 -C 12 -aryloxy, C 7 -C 13 -aralkyloxy, hydroxy-C 1 -C 8 -alkyl, carboxy-C 1 -C 12 -alkyl, C 1 -C 12 -alkoxycarbonyl-C 1 -C 12 -alkyl, C 2 -C 30 -alkyl, which is interrupted by one or more oxygen atoms, C 2 -C 16 -alkyl, which is interrupted by one sulfur atom, or NR′ 1 R′ 2 ; when n is 2, R 5 is C 1 -C 12 -alkane-diyl, C 6 -C 14 -arylene, C 4 -C 8 -cycloalkane-bis-(C 1 -C 4 -alkylene), C 6 -C 14 -arene-bis-(C 1 -C 4 -alkylene), C 4 -C 24 -alkane-diyl, which is interrupted by one or more oxygen atoms, C 4 -C 20 -alkane-diyl, which is interrupted by one or more —NH—, —N(C 1 -C 8 -alkyl)- or —N(hydroxy-C 1 -C 8 -alkyl)-, piperazine-N,N′-bis-(C 1 -C 4 -alkylene) or C 2 -C 10 -alkane-diyl, which is interrupted by one sulfur atom; R 1 to R 4 and R 6 to R 9 are each independently from each other H, C 1 -C 12 -alkyl, C 3 -C 10 -cycloalkyl, C 3 -C 22 -alkenyl, C 1 -C 12 -alkoxy, C 1 -C 12 -alkylsulfanyl, hydroxy-C 1 -C 8 -alkyl, halogen, NR″ 1 R″ 2 , NO 2 , CN, phenyl, phenyloxy or R 1 and R 2 or R 2 and R 3 or R 3 and R 4 or R 6 and R 7 or R 7 and R 8 or R 8 and R 9 are linked together to form a five- or 6-membered alicylic, aromatic or heterocyclic ring together with their 2 corresponding carbons atoms, to which they are attached.
