    • Tuning, locking, and shimming of the NMR probe had to be performed at 100°C since the settings were too much different from the settings at ambient temperature. In addition, optimization of the probe had to be redone regularly during the polymerization because the sample with different amounts of polymer inside required different shims than the initial mixture.
