| Abstract | A series of novel aromatic poly(ether imides) with inherent viscosities of 0.48–0.70 dL/g and weight-average molecular weights of 18,800–40,500 g/mol were successfully prepared from two dianhydride and two diamine monomers containing pyridine moiety via both two-step method and one-step method. Comparison of the one-step and the two-step methods for the preparation of poly(ether imides) was carried out and shown that poly (ether imides) obtained via one-step method exhibited higher molecular weights than the similar polymers pre- pared through two-step process. Poly(ether imide) resins obtained via both one-step and two-step methods with sub- sequent chemical dehydration showed good solubility not only in high boiling point solvents but also in low boiling point solvents. High-quality poly(ether imide) films could be obtained via the two-step method with subsequent ther-mal imidization, which exhibited excellent thermal proper- ties with glass transition temperatures of 239–278 C, initial decomposition temperatures of 540–574 C, residual weight percent at 800 C of 64.5–69.3% under nitrogen, good thermo-oxidative stability with initial decomposition tem- peratures of 521–544 C, residual weight percent at 800 Cof 33.6–51.1% under air atmosphere, outstanding mechanical properties with tensile strengths in the range of 104.6–109.4 MPa, tensile modulus in the range of 1.92–2.58 GPa, and elongation at break from 6.9 to 8.0%, as well as good trans- parency with cutoff wavelengths of 386–392 nm and low dielectric constants of 2.80–2.92 at 1 MHz. |
