The curing reaction of benzoxazine with bismaleimide/cyanate ester resin and the properties of the terpolymer

Incorporation of benzoxazine into bismaleimide/cyanate ester resin can induce an interpenetrating network (IPN) structure. With the content of benzoxazine increases, the fracture surface of BOZ/BMI/BADCy will change from riverlike shape to ductile sunken shape.323
