Poly-L-Lactic Acid

American Journal of Clinical Dermatology, 2004
Poly-L-lactic acid, a synthetic biodegradable polymer, is available as an injectable intradermal implant for use in the correction and restoration of the signs of facial lipoatrophy in patients with HIV infection. In a 96-week noncomparative study in HIV-infected patients with severe facial lipoatrophy, 41% of patients treated with intradermal poly-L ...

Properties of poly (l-lactic acid) reinforced by l-lactic acid grafted nanocellulose crystal

International Journal of Biological Macromolecules, 2020
In this research, nanocellulose crystal (NCC) grafted with lactic acid (LA) oligomer was synthesized by one-pot method and used to reinforce the poly(l-lactic acid) (PLLA) matrix. FT-IR, XRD, and 13C NMR were used to analyze the structure of modified nanocellulose crystal (g-NCC).

Raman spectra of glycolic acid, l-lactic acid and d,l-lactic acid oligomers

Spectrochimica Acta Part A: Molecular Spectroscopy, 1993
Abstract Polymerization of glycolic acid, l - and d,l -lactic acid was followed by Raman spectroscopy in aqueous solution at different concentrations, in viscous and solid states. The Raman spectra of some oligomers obtained by progressive polycondensation of α-hydroxycarboxylic acid aqueous solutions were investigated in the 200–18 cm −1 region ...
