| Abstract: | The reactivity and viscosity behavior of BMI resin was measured, and then rheological property was studyed. The initial temperature,peak temperature and terminate temperature obtained from DSC analysis were 202 ℃ ,266 ℃ and 320 ℃ respectively; Arrhenius equation showed that activation energy was 58.1 kJ/mol. Viscosity-temperature and viscosity-time curves were obtained from rotational viseometer. The resin system which had excellent processing property had a wider and lower working platform between 140 ℃ - 180 ℃. The viscosity less than 300 mPa. s below 140 ℃can remain 50 min. |
