| Abstract: | The curing reaction and kinetics of diaamine - benzoxazine precusors/bisoxazoline blends were investigated by FTIR and DSC methods. The curing process was also determined. Results showed that the average active energy of diaamine - benzoxazine precusors/bisoxazoline blends was 90.36 kJ/mol and the grade of reaction was 0. 93. The curing process was 170 ℃/2h, 190℃/2h,200℃/2h;later treating process was 230 ℃/2h. |
