Synthesis and characterization of polyimides prepared from optically active (R,R) and (S,S)-1,3-bis (p-N,N'- dimethylaminobenzyl)-perhydrobenzimidazol-2-thion.

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.trinfo:eu-repo/semantics/openAccessSynthesis and characterization of polyimides prepared from optically active (R,R) and (S,S)-1,3-bis (p-N,N'- dimethylaminobenzyl)-perhydrobenzimidazol-2-thionArticle31211312467287
