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.

加成二烯聚合中链支化模型的判别
本工作仅根据平均分子量和反应过程中监测到的单体转化率（通常在大多数工业工厂的质量控制实验室中进行），分析了在除二烯聚合以外是否有可能区分链支化模型。此外，还验证了所分析的模型是否具有足够的灵活性以适合其他竞争对手模型生成的数据。考虑了三种动力学模型，并且改变了动力学参数以代表平均分子量和单体转化率，这通常是在加成二烯聚合中发现的。结果表明，即使只有通过GPC分析测得的平均分子量，通过很少的实验，模型鉴别的确是可行的，
