                         copolymerization is an interesting procedure from an economic 
                         standpoint; however, its mathematical representation is of great 
                         complexity. In the present study, modeling tools were used to 
                         describe the copolymerization of styrene with ethylene glycol 
                         dimethacrylate (EGDMA) beyond the gel point. Balance of species 
                         and sequences, method of moments, and numerical fractionation 
                         technique were applied in the model's kinetic description. 
                         Diffusion effects were also taken into account. The concept of 
                         elementary gel structures (EGSs) was used in order to predict 
                         textural properties of polymer particles, such as specific surface 
                         area and swollen gel volume. Suspension copolymerizations were 
                         carried out in the presence of toluene/heptane mixtures, and data 
                         on these reactions were used to assess the model's predictability. 
                         Reactivity parameters showed similarities to 
                         styrene/divinylbenzene systems. Agreement between the model and 
                         experimental data improved when diffusion effects were considered. 
                         The fitted apparent coiling factors for dry particles were found 
                         in the range of 0.3680.406, and a linear correlation was obtained 
                         between this parameter and toluene fraction (a good solvent), 
                         being consistent with the pore formation phenomenon.",
