【 摘 要 】

A novel benzoxazine with cyano group (CP-apa) was synthesized to study the impacts of cyano group on the properties of benzoxazine. The properties of CP-apa were compared with P-apa. DSC and FT-IR were used to track the curing reaction of CP-apa and P-apa.CP-apa shows excellent curing behaviors. Afterwards, the mechanical properties and heat resistance of the thermosets were investigated. The introduction of -CN would decrease the mechanical properties of cured CP-apa, but the good heat resistance of benzoxazine still remains.
