Abstract—Amino-containing homo- and copolyesters were prepared from tere- and isophthaloyl dichlorides,
N-methyldiethanolamine, and bisphenol by acceptor-catalytic (co)polyesterification with the aim of synthesiz-
ing biomimetic condensation heterochain copolymers. Depending on the copolycondensation technique used,
copolyesters with different microstructures varying from random to block were formed. The microstructure of
N-methyldiethanolamine copolyterephthalate in which a part of the amino groups was converted into hydro-
chloric or quaternized by butyl iodide was estimated by ¹H NMR spectroscopy.
