快速和强放热的乳液聚合方法特别难以从安全性和生产率两个角度优化，因为会发生许多不希望的副反应（例如，叔自由基的增长、链转移到单体、反咬（backbiting）、通过反离子化的终止等）以及在大气压下引发沸腾现象并随之形成稳定的泡沫。因此，这将是有用的，以开发一个合适的理论和实验相结合的程序，能够检测最佳的工艺投料时间和初始反应器温度。在这项工作中，它是如何讨论的拓扑标准理论，最初开发的isoperibolic半间歇式反应器的扩展版本，可以用来安全地优化间接冷却等温半间歇式反应器。此外，这种方法被应用到一个案例研究为代表的聚（丙烯酸丁酯）通过自由基乳液聚合的丁基丙烯酸酯的合成。
Fast and strongly exothermic emulsion polymerization processes are particularly difficult to optimize from both safety and productivity points of view because of the occurrence of a number of undesired side reactions (e.g., propagation of tertiary radicals, chain transfer to monomer, backbiting, termination by disproportionation, etc.) and the triggering of boiling phenomena with consequent stable foam formation under atmospheric pressure. Therefore, it would be useful to develop a suitable combined theoretical and experimental procedure able to detect both the optimum process dosing time and initial reactor temperature. In this work, it is discussed how an extended version of the topological criterion theory, originally developed for isoperibolic semibatch reactors, can be used to safely optimize an indirectly cooled isothermal semibatch reactor. Moreover, such a methodology is applied to a case study represented by the synthesis of poly(butyl acrylate) through the radical emulsion polymerization of buty...
