Kinetic parameters were calculated based on the curve of reactive temperature rise measured with the adiabatic approach in the temperature range of 145℃ to 160℃ for the catalytic system of NaOH and acyl caprolactam end-capped butadiene-acrylonitrile rubber (CHTBN) or styrene-butadiene rubber (CHTBS).The reaction was first order

the activation energy was between 72.91—73.16 kJ·mol-1 and the pre-exponential factor was between 3.22×1011— 3.38×1011mol 1-n·s-1 in the system of CHTBN/NaOH.While in CHTBS/NaOH

the reaction order was between 1.23—1.34

the activation energy was between 85.55—86.88 kJ·mol-1 and the pre-exponential factor was between 4.52×1011—5.09×1011mol 1-n·s-1.The adiabatic reaction kinetic model of caprolactam anion was established based on prior research findings

and the polymerization reaction was simulated with the kinetic model. The agreement between simulation results and experimental data showed that the model was reasonable and correct.
