摘要
The present disclosure provides a polymerizable thermosetting composition comprising an acetylene-bearing benzoxazine compound and a phthalonitrile monomer. The composition can provide a low viscosity for RTM application and can fully cured at a much lower temperature than the phthalonitrile monomer. The cured thermoset polymers having excellent thermal and mechanical properties, such as high thermal stability, heat resistance, high char yield, and enhanced structural rigidity.
