Progress in research on modification of heat resistance of benzoxazine resin

The progress in studies of modification of heat resistance of benzoxazine resin as a novel thermosetting resin at home and abroad in recent years was reviewed in terms of molecular structure design,inorganic particles modification,alloy or copolymerization modification and synthesis of novel benzoxazine.The development trend of benzoxazine resin in the future was forecasted.Molecular structure design generally involved the utilization of flexibility of the benzoxazine molecules so as to introduce reactive groups or rigid groups into the benzoxazine molecules.The studies showed that every modification method could improve remarkably the heat resistance of the benzoxazine resin from different aspects.
