ABSTRACT > The polyamide 1 (PA1) containing the highest density of hydrogen bond and dipole was synthesized using carbon dioxide (CO <sub>2</sub> ) and urea as raw materials under supercritical CO <sub>2</sub> condition through environment‐friendly method. Three kinds of molecular weights of PA1 were prepared in this study to satisfy different application areas. The chemical structures of PA1 were characterized comprehensively by means of 1 H and 13 C NMR, Fourier transform infrared spectroscopy, elements analysis, intrinsic viscosity, and wide angle X‐ray diffraction. The thermal properties and glass transition temperature were measured by thermogravimetric analysis (TGA) and differential scanning calorimetry. The obtained products had intrinsic average molecular weights ranging from 1.29 × 10 3 to 1.29 × 10 4 . And the thermal stability and glass transition temperature increased with the increasing of molecular weight. TGA results indicated that the temperatures of 5% and 10% weight loss were 378 and 395 °C, respectively and the maximum decomposition temperatures for the two stages were 416 and 457 °C for the highest molecular weight product. The PA1, a new family member of polyamides, was a potential multifunctional material and found applications as high‐performance material. ? 2018 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym.
