Cationic polymerization of glycidol: coexistence of the activated monomer and active chain end mechanism

Preparation and properties of multi-branched poly(D-lactide) derived from polyglycidol and its stereocomplex blends

“…Detailed information on chemical structure of PG can be derived from 13 C NMR Inverse Gated spectra, in which complicated patterns of perfect dentritic (D), linear (L), and terminal (T) units can be identified. The assignments have been applied to 13 C NMR (b), and 13 C NMR DEPT (c) spectra of PG synthesized from tin catalyst the spectra of PG synthesized from anionic polymerization [41][42][43][44]. Similar spectral characteristics are observed in this study, in which a tin catalyst is employed, as shown in a 13 C NMR and a distortionless enhancement by polarization transfer (DEPT) spectra in Figure 1b and 1c, respectively.…”

“…The relative intensity of the high-molecular weight fraction increases with the decrease in the catalyst contents. Although the polydispersity value (~3.4) is significantly high, compared to that obtained from anionic polymerization [41][42][43][44], this synthesis route is considered as an alternative approach when structural perfection may not be a strict requirement for most applications.…”

Glycerol based polyether-nanogels with tunable properties via acid-catalyzed epoxide-opening in miniemulsion

“…Vandenberg [26] and later extended by Penczek [27] and Dworak [28]. Calculation of the degrees of branching, however, was only possible after Frey utilized inverse …”

Novel application of double metal cyanide in the synthesis of hyperbranched polyether polyols

“…Therefore, it is appropriate to discuss the results of this method in detail. Signal assignments for 13 C NMR spectra of polyglycerol were first reported by Vandenberg [21] and extended by Penczek and Dworak [22]. The 13 C NMR spectrum of the hyperbranched polyether polyols possesses seven well-resolved peak regions between 15 and 80 ppm (Figure 4).…”
