Ring-opening-isomerization anionic polymerization Brook rearrangement.

Ring-opening isomerization polymerization was developed using a combination of a ring-opening reaction of epoxides and subsequent Brook rearrangement. An epoxy monomer with a benzyltrimethylsilyl group was designed for the polymerization. Characterization of the obtained polymer by NMR and MALDI-TOF-MS indicated that polymerization proceeded exclusively a ring-opening-isomerization anionic polymerization mechanism.
