AbstractA novel PLA‐based polymer containing reactive pendent ketone or hydroxyl groups was synthesized by the copolymerization of L‐lactide with ε‐caprolactone‐based monomers. The polymer was activated with NPC, resulting in an amine‐reactive polymer which was then cast into thin polymeric films, either alone or as part of a blend with PLGA, before ...

Biodegradable poly(lactic acid) polymers
Journal of Biomedical Materials Research, 1971AbstractThe synthesis of poly(lactic acids) from the cyclic lactides and properties of the polymers prepared have been described. Degradation rates in vitro under homogeous and heterogeneous conditions have been measured. The kinetics of deesterification under homogeneous conditions is second order and an activation energy of 11 Kcal/mol has been ...

Electrospinning of Poly(Lactic Acid)/Poly(Lactic Acid-Co-Lysine) Blend
Applied Mechanics and Materials, 2014Electrospun poly (lactic acid)/poly (lactic acid-co-lysine) (PLA/PLL) blend were prepared, and the structures including fibers, beads and microspheres and properties of electrospun material were characterized. Viscosity, conductivity and surface tension of electrospinning solution had critical effect on the structures of the electrospun blend.

Poly(lactic acid) based hydrogels
Advanced Drug Delivery Reviews, 2016Polylactide (PLA) and its copolymers are hydrophobic polyesters used for biomedical applications. Hydrogel medicinal implants have been used as drug delivery vehicles and scaffolds for tissue engineering, tissue augmentation and more. Since lactides are non-functional, they are copolymerized with hydrophilic monomers or conjugated to a hydrophilic ...

Amorphous Fractions of Poly(lactic acid)
2017Detailed knowledge of the organization of amorphous and crystalline phases in a semicrystalline polymer such as poly(L-lactic acid) (PLLA) is crucial for complete understanding and prediction of its physical properties. In semicrystalline polymers, amorphous segments located at different distances from the crystalline domains can exhibit different ...

Processing of Poly(lactic Acid)
2017Polymer applications range from biomedical devices and structures, packaging, or toys to automotive and industrial items. So far, biopolymers could replace commodity polymers in a variety of products, especially for biomedical applications or food packaging. One of the most used and widely studied biopolymers is poly(lactic acid) (PLA). To generate new
