| Popis: | The main objective of this research was to study the structure–property relationships to high performance polymers with thermal stability, solubility and viscosity. Hence, a series of novel poly(amide-imide)s (PAIs) was synthesized from a tetraphenylthiophene-thiazole containing diimide-diacid(TPTPThDIDA) monomer with commercially available various aromatic diamines by using Yamazaki’s direct phosphorylation reaction. The resulting PAIs were obtained in high yields and inherent viscosities in the range of 0.86–0.96 dL/g. The reinforcement of the heterocyclic thiazole ring unit on the properties of these PAIs was studied by comparison of the corresponding polymers containing tetraphenylthiophene groups. The PAIs exhibited excellent solubility and good thermal stability. PAIs showed high glass-transition temperatures in the range of 267 °C–302 °C. Thermogravimetric analysis of the PAIs indicated a 10% weight loss (T10) in the temperature range of 609–736 °C and char yields at 900 °C under nitrogen a... |
