Abstract

The present invention provides a polymerizable thermosetting composition comprising an acetylene-containing benzoxazine compound and a phthalonitrile monomer. The composition can provide a low viscosity for RTM and can be fully cured at a temperature much lower than that of the phthalonitrile monomer. The cured thermosetting polymer has excellent thermal and mechanical properties, such as high thermal stability, heat resistance, high carbon residue rate and enhanced structural rigidity.
