Aliphatic polyesters: great degradable polymers that cannot do everything.
Nowadays the open and the patent literatures propose a large number of polymers whose main chains can be degraded usefully. Among these degradable polymers, aliphatic polyester-based polymeric structures are receiving special attention because they are all more or less sensitive to hydrolytic degradation, a feature of interest when compared with the fact that living systems function in aqueous ...
متن کاملSingle crystal morphologies of biodegradable aliphatic polyesters
Single crystals of biodegradable aliphatic polyesters, poly([R]-3-hydroxybutyrate), poly([R]-3-hydroxyvalerate), poly(L-lactic acid), poly( -propiolactone), poly(4-hydroxybutyrate), poly(Æ-valerolactone), poly("caprolactone), poly(ethylene succinate) and poly(tetramethylene adipate), were grown from dilute solution by isothermal crystallization, and the crystal structures and morphologies were ...
متن کاملSolvent induced rapid modulation of micro/nano structures of metal carboxylates coordination polymers: mechanism and morphology dependent magnetism
Rational modulation of morphology is very important for functional coordination polymers (CPs) micro/nanostructures, and new strategies are still desired to achieve this challenging target. Herein, organic solvents have been established as the capping agents for rapid modulating the growth of metal-carboxylates CPs in organic solvent/water mixtures at ambient conditions. Co-3,5-pyridinedicarbox...
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 کاملMetal aminocarboxylate coordination polymers with chain and layered structures.
The synthesis and structures of metal aminocarboxylates prepared in acidic, neutral, or alkaline media have been explored with the purpose of isolating coordination polymers with linear chain and two-dimensional layered structures. Metal glycinates of the formulae [CoCl2(H2O)2(CO2CH2NH3)] (I), [MnCl2(CO2CH2NH3)2] (II), and [Cd3Cl6(CO2CH2NH3)4] (III) with one-dimensional chain structures have be...
