摘要

This work covered the talcum filled with ethylene-propylene-terpolymer (EPDM), and the cure curve was obtained by oscillating disc rheometer under isothermal. By taking first-order-derivative and second-order-derivative of cure conversion respect to time, three characteristic time (t_p, t₁, t₂) was obtained. So the process of vulcanization could be division to four regions. The characteristic of cure time (t_p, t₁, t₂) vs. 1/T is an exponential type dependence, a model of autocatalytic reaction governs the process of vulcanization. With the loading of talcum increasing, the activation energy of the system decreases from 98.7269 kJ/mol to 77.69 kJ/mol.
