| Popis: | The aim of this work is it to develop a measuring method which allows to detect and quantify the influence of the fluid dynamics on polymerization kinetics. Such a dependency has been claimed previously. However, yet there is no analytical method available which gives insight into the phenomena observed on a molecular level. Rheo-NMR is a technique, which is particularly suitable to analyze such phenomena. Hence, a temperature controlled Rheo-NMR measuring cell was constructed. The validation of the concept is demonstrated on a model system, the free radical polymerization of methyl methacrylate. |
