| description | There is an urgency to produce novel high-performance resins to support the rapid development of the aerospace field and the electronic industry. In the present work, we designed and consequently synthesized a benzoxazine monomer (<b><i>o</i>HPNI-fa</b>) bearing both norbornene and furan groups through the flexible benzoxazine structural design capability. The molecular structure of <b><i>o</i>HPNI-fa</b> was verified by the combination characterization of nuclear magnetic resonance spectrum, FT-IR technology, and high-resolution mass spectrum. The thermally activated terpolymerization was monitored by in situ FT-IR as well as differential scanning calorimetry (DSC). Moreover, the low-temperature-curing characteristics of <b><i>o</i>HPNI-fa</b> have also been revealed and discussed in the current study. Furthermore, the curing kinetics of the <b><i>o</i>HPNI-fa</b> were investigated by the Kissinger and Ozawa methods. The resulting highly cross-linked thermoset based on <b><i>o</i>HPNI-fa</b> showed excellent thermal stability as well as flame retardancy (T<sub>d10</sub> of 425 °C, THR of 4.9 KJg<sup>−1</sup>). The strategy for molecular design utilized in the current work gives a guide to the development of high-performance resins which can potentially be applied in the aerospace and electronics industries. |
