N,N?-dimethylaminobenzyl)- perhydrobenzimidazol-2-thion unit in the backbone. The reactions occur between equimolar amounts of a dianhydride and an aromatic dimethylamine in the presence of the solvent N-methyl-2-pyrollidone (NMP). In this work, the chiral monomer RR and SS -1,3-bis(p ? N,N?-dimethylaminobenzyl)-perhydrobenzimidazol-2- thion were used as diamines. The polyimides obtained were characterized by thermogravimetry (TGA), differential thermal analysis (DTA), differential scanning calorimeter (DSC), infrared spectroscopy (FT-IR), and gel permeation chromatography (GPC). It was found that the composition of the polymer had a significant effect upon the thermal behavior of the material. © TÜBİTAK.eninfo:eu-repo/semantics/closedAccessDianhydrideOptically active polymersPolyimidesThermally stable polymersArticle3121131242-s2.0-34247506390Q3
