| الوصف: | Free radical polymerization of methyl methacrylate was investigated in the presence of azo and organic peroxide initiator, such as 2,2′-azobisisobutyronitrile (AIBN), 1,1-bis(tert-butylperoxy)cyclohexane (BTBPC), tert-butyl peroxyneodecanoate (TBPND), and tert-butyl peroxy-2-ethylhexanoate (TBPEH) under isothermal condition (Tiso=60∼90 °C). The reaction heat generated in the bulk polymerization of methyl methacrylate was measured using a differential scanning calorimeter (DSC). The degree of polymerization and its reaction rate were expressed as a function of conversion (α) and its rate (dα/dt), respectively. We confirmed that autoacceleration proceeded predominantly during the autoacceleration regime (τauto) appearing after the onset of autoacceleration of MMA polymerization. In this work, kinetic models consisting of two contributions, such as n th order reaction and a kinetic equation representing autoacceleration, were suggested. The combined kinetic models were simulated and compared with the experimental data to evaluate the reliabilities. |
