Synthesis of narrow molecular weight distribution α,ω-hydroxy telechelic polyoxetane by the activated monomer mechanism

Abstract The cationic activated monomer mechanism has been used to prepare polyoxetane (poly(trimethylene oxide)) with low dispersities, hydroxy functional end groups and without significant oligomer contamination. Tetrafluoroboric acid and 1,4-butandiol were used as the catalyst system. The polymer has been characterized by n.m.r. and s.e.c.
