Abstract
A polymer comprising at least one unit of the formula (1) wherein T1 is a carbon atom or a nitrogen atom, T2 is a carbon atom if T1 is a nitrogen atom, or is a nitrogen atom if T1 is a carbon atom, r is 1, 2, 3 or 4, s is 1, 2, 3, or 4, M1 is preferably selected from the group consisting of M2 is preferably The polymers are prepared by reacting monomers (1a) with monomers (2a) H2N-[-M1-]r-NH2 (1a) OHC-[-M2-]s-CHO (2a) or the step of reacting monomers (1b) with monomers (2b) OHC-[-M1-]r-CHO (1b) H2N-[-M2-]s-NH2 (2b).
