Alternating copolymerization of epoxides and cyclic anhydrides: an improved route to aliphatic polyesters.
Aliphatic polyesters constitute an important class of polymers because of their biodegradability1,2 and biocompatability,2,3 which enable their use in drug delivery systems,2 artificial tissues,3 and commodity materials.4 Polyesters such as poly(butylene succinate) are commonly produced through condensation polymerization; however, this method is energy intensive, requiring high temperature and...
متن کاملReversible-deactivation anionic alternating ring-opening copolymerization of epoxides and cyclic anhydrides: access to orthogonally functionalizable multiblock aliphatic polyesters† †Electronic supplementary information (ESI) available: Synthetic, polymerization, and functionalization procedures, and characterization data. See DOI: 10.1039/c7sc03643d
The alternating copolymerization of epoxides and cyclic anhydrides is an increasingly popular route to aliphatic polyesters that are of interest as biodegradable replacements for petroleum-based polymers and for use in the biomedical field. However, broad and bimodal molecular weight distributions in these polymerizations continues to be an issue, limiting synthesis of multiblock copolymers. By...
متن کاملReactivity ratios, and mechanistic insight for anionic ring-opening copolymerization of epoxides.
Reactivity ratios were evaluated for anionic ring-opening copolymerizations of ethylene oxide (EO) with either allyl glycidyl ether (AGE) or ethylene glycol vinyl glycidyl ether (EGVGE) using a benzyl alkoxide initiator. The chemical shift for the benzylic protons of the initiator, as measured by (1)H NMR spectroscopy, were observed to be sensitive to the sequence of the first two monomers adde...

متن کاملRing-opening copolymerization (ROCOP): synthesis and properties of polyesters and polycarbonates.
Controlled routes to prepare polyesters and polycarbonates are of interest due to the widespread application of these materials and the opportunities provided to prepare new copolymers. Furthermore, ring-opening copolymerization may enable new poly(ester-carbonate) materials to be prepared which are inaccessible using alternative polymerizations. This review highlights recent advances in the ri...
