Abstract A novel boron‐containing hyperbranched benzoxazine (HB‐B) was synthesized from the reaction of triethanolamine borate (BAE), bisphenol‐A, and paraformaldehyde via Mannich condensation. The chemical structures BAE HB‐B were characterized by Fourier transform infrared (FT‐IR) hydrogen nuclear magnetic resonance ( 1 H NMR). Afterward, benzoxazine/epoxy resin copolymers (E51/HB‐B) prepared. curing behavior ‐B E51/HB‐B studied FT‐IR differential scanning calorimeter (DSC). thermal...

Divergent synthesis of 2-pyridones.
Synthesis of polysubstituted 2‐pyridones and their analogues from β‐keto amides via self‐condensation cyclization is described. Notable advantages include mild reaction conditions, reduced synthetic steps, high yields, a readily available starting materials. Further mechanistic studies suggest that the transformation proceeds through self‐condensation, intramolecular nucleophilic cyclization, elimination.
Abstract Cyanate ester (CE) resins possess excellent thermal and mechanical characteristics, yet their brittleness high cross‐link density limit practical application. To overcome this limitation, the modification of CE with thermoplastic has been employed as an effective strategy to enhance toughness properties. In study, a novel fluorinated poly(aryl ether nitrile) (PFPEN) solubility properties was synthesized through nucleophilic substitution reaction. The effect addition PFPEN on blend...
