摘要: Earlier published rheological data of methyl methacrylate (MMA) heated and isothermally polymerized at temperatures between 50 80 � C have been reanalyzed using three semiempirical models viscosity advancement including a modified Boltzmann sigmoidal model, micro- gel model for cure, first-order isothermal kinetic model. These alternative possessed few fitting pa- rameters could be used without requiring more experi- ments to run. For each dataset as function temperature, the analysis resolved time constants associated with both induction polymerization rate rise, which were inversely related poly- merization temperature. We found most robust accommodate nonlinearities in radical MMA. V 2010
