Cationic Ring Opening Polymerization of Oxazolines Initiated by Trimethylsilyl Derivatives.

摘要

Cationic polymerization of oxazolines was initiated by trimethylsilyl triflate and trimethylsilyl iodide. Initiation is slow due to the formation of a imine dimeric cation which is very unreactive toward oxazoline. The presence of the imine dimeric cation was confirmed by NMR and FAB-MS.
