Characterization of Aliphatic Polyesters Synthesized via Enzymatic Ring-Opening Polymerization in Ionic Liquids.
To evaluate the effects of ionic liquids (ILs) on the microstructural features of aliphatic polyesters for biomedical applications, a series of copolymers were synthesized by lipase ring opening polymerization of rac-lactide (rac-LA) and ε-caprolactone (CL). The chemical structures of resulting polymers were characterized by ¹H- and 13C-NMR and the average molecular weight (Mn) and dispersity i...
متن کاملRecent advances in the synthesis of aliphatic polyesters by ring-opening polymerization.
Advanced drug delivery systems rely on the availability of biocompatible materials. Moreover, biodegradability is highly desirable in the design of those systems. Consequently, aliphatic polyesters appear as a class of promising materials since they combine both properties. Nevertheless, their use in practical biomedical systems relies on clinical approval which not only depends on the material...
متن کاملPrecision Aliphatic Polyesters via Segmer Assembly Polymerization.
Precise structure-property relation of a biodegradable polymer (e.g., aliphatic polyester) is anticipated only if monomer units and chiral centers are arranged in a defined primary sequence as a biomacromolecule. An emerging synthetic methodology, namely segmer assembly polymerization (SAP), is introduced in this paper to reveal the latest progress in polyester synthesis. Almost any periodic po...
متن کاملSynthesis and Characterization of Cellulose-graft- poly(p-dioxanone) Copolymers via Homogeneous Ring- Opening Graft Polymerization in Ionic Liquids
Cellulose-graft-poly(p-dioxanone) copolymers (cellulose-g-PPDO) were homogeneously prepared via ring-opening graft polymerization (ROP) between p-dioxanone (PDO) and hydroxyl groups of cellulose using the catalyst 4-dimethylaminoptridine (DMAP) in the ionic liquid 1-butyl-3methylimidazolium chloride (BmimCl). Chemical structures and physical properties of the cellulose-g-PPDO copolymers were ch...
متن کاملPolymersome nanoreactors for enzymatic ring-opening polymerization.
Polystyrene-polyisocyanopeptide (PS-PIAT) polymersomes containing CALB in two different locations, one in the aqueous inner compartment and one in the bilayer, were investigated for enzymatic ring-opening polymerization of lactones in water. It is shown that the monomers 8-octanolactone and dodecalactone yield oligomers with this polymersome system. It is also observed that the polymerization a...
