This study reports the optimization of a synthetic resin reaction. The synthesis reaction of resins is normally called the polymerization reaction. The authors have applied Quality Engineering methods to the synthesis reaction of organic substances using Dynamic Operating Window approach and successfully doubled the reaction speed. As a result, however, there was a problem regarding the reproducibility of conclusions due to the occurrence of mountain shapes and valley shapes in the response graphs. In order to solve this problem,a new approach was tried by analyzing the ratio of the main reaction speed (β1) and the side reaction speed (β2). From the analysis, good reproducibility was obtained. This polymerization study was conducted based on the experience of the previous organic synthesis reaction using a new way of evaluating the molecular weight distribution and the new SN ratio.
