Polyglycolic acid solubility
PLGA, PLG, or poly(lactic-co-glycolic acid) is a copolymer which is used in a host of Food and Drug Administration (FDA) approved therapeutic devices, owing to its biodegradability and biocompatibility. PLGA is synthesized by means of ring-opening co-polymerization of two different monomers, the cyclic dimers (1,4-dioxane-2,5-diones) of glycolic acid and lactic acid. Polymers can be synthesize… http://kinampark.com/PL/files/Tang%202415%2C%20Hansen%20solubility%20parameters%20of%20polyglycolic%20acidand%20interaction%20parameters%20between%20polyglycolicacid%20and%20solvents.pdf
