✦ Synopsis
Polymerization of 2-methyl-2-oxazoline was carried out using a trifunctional initiator, 2-perbromomethyl-2-oxazoline. The degree of polymerization (DP) of the resulting polymer was very close to the feed mole ratio of the monomer to initiator. The number-average molecular weight a, increased linearly with conversion, indicating the living nature of the propagating chain end. 'H NMR and end-group analyses results are consistent with the proposal that the polymer possesses a star-shaped structure.

## Abstract **Summary:** The use of microwave heating in polymer science is a rapidly growing field of research leading to faster and cleaner polymerization procedures. However, the majority of the investigations are performed at small scales (≈1 mL), which is far away from potential commercial app
## Abstract Microwave‐assisted polymerizations is a growing field of interest because the use of microwave irradiation instead of thermal heating was demonstrated to result in faster, cleaner, and higher yielding reactions. To overcome the one‐at‐a‐time nature of preparing polymerizations in single
