Xu, Jianjun published the artcileSynthesis and properties of a high-performance pyrimidine-containing self-catalyzed phthalonitrile polymer, Synthetic Route of 56-05-3, the publication is Journal of Polymer Science, Part A: Polymer Chemistry (2019), 57(23), 2287-2294, database is CAplus.
A self-catalytic monomer of phthalonitrile, 2-amino-4,6-bis[3-(3,4-dicyano-phenoxy)phenoxy] pyrimidine (ACPP), was synthesized by a one-pot method with resorcinol, 2-amino-4,6-dichloropyrimidine, and 4-nitrophthalonitrile. The chem. structure of the ACPP monomer was characterized by Fourier transform IR spectroscopy and NMR spectroscopy. The curing behavior of ACPP monomer was studied by differential scanning calorimetric, which indicated that the ACPP monomer had a low m.p. (84 °C) and revealed an autocatalytic reaction and tremendously wide processing window (193 °C). Wide-angle X-ray diffraction and FTIR analyzes were employed to explore the microstructure of the ACPP polymers. The properties of the three polymers with different curing procedures were investigated, which implied that the ACPP polymers exhibited excellent thermal stability, high modulus, superior glass-transition temperature (Tg > 400 °C), and low water absorption with the increase in curing extent.
