Abstract:

The chemorheology behaviors of curing reaction of benzocyclobuteneterminated imide were studied with rheometer.The curing process was investigated by dynamic heating and isothermal methods,and three curing stages were found.Apparent physical activation energy of flow calculated by Arrhenius equation was 195.9kJ/mol.Apparent chemical activation energy of flow and apparent curing reaction activation energy were calculated by Roller equation, respectively.The results show that the viscosity characteristic of resin follows the Roller equation very well, and viscosity characteristic of resin can be predicted by the Roller equation in the whole curing process.
