Synthesis and structural study of poly(thioether imide)s based on Aromatic heterocyclic diimide
Novel poly(thioether imide)s were prepared from aromatic heterocyclic chlorodiimids and 1,6-hexanediol by a nucleophilic substitution reaction in the presence of alkali catalysts. All the polycondensation proceeded smoothly in DMAc and the polymers were obtained quantitatively. The poly(thioether imide)s were soluble in some polar solvents and possessed excellent thermal properties. The glass transition temperatures of resultant polymers were beyond 215℃ and 10% weight loss temperatures were in the range of 450～500℃ under nitrogen atmosphere. Meanwhile, the dilute solution of these polymers in chloroform showed strong optical absorption in ultraviolet region, and exhibited green yellow fluorescence with emission maxima at 400～650 nm. Due to their properties, these poly(thioether imide)s could be considered as good potential candidates for high-temperature resistant materials and fluorescent materials.
