Glycidol represents a latent cyclic AB2-type monomer that can be polymerized in a ring-opening multibranching polymerization (ROMBP). Hyperbranched aliphatic polyethers with controlled molecular weights and narrow molecular weight distribution have been prepared via anionic polymerization of glycidol with rapid cation-exchange equilibrium. 1,1,1-Tris(hydroxymethyl)propane (TMP) was partially deprotonated (10%) and used as initiator for the anionic polymerization carried out under slow addition conditions to minimize polymerization without initiator as well as cyclization. 13C NMR spectra were employed to assess the degree of branching (DB), which was in the range 0.53−0.59. 13C NMR, MALDI-TOF mass spectrometry, vapor pressure osmometry (VPO), and GPC were used to characterize molecular weights and polydispersities of the polyols formed, showing good agreement. n for the polymers prepared was in the range 15−83 (Mn = 1250−6500), and Mw/Mn obtained was 1.13−1.47, being exceptionally low for hyperbranched...
