- Abstract
The present work analyzes whether discrimination of chain branching models is possible in addition diene polymerizations, based solely on average molecular weights and monomer conversions monitored during the reaction course, as usually performed in most quality control labs of industrial plants. In addition, it is verified whether the analyzed models present enough flexibility to fit data generated with the other rival models. Three kinetic models are considered, and kinetic parameters are varied in order to represent average molecular weights and monomer conversions that are typically found in addition diene polymerizations. The results show that model discrimination is indeed feasible with few experiments, even when only average molecular weights measured through GPC analyses are available, which can be of significant practical importance at plant site for critical characterization of product properties and process performance.
