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

Öz:
This paper presents the synthesis and characterization of polyimides containing a chiral (R,R)or (S,S) 1,3-bis(p-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.
