应用

Different from common Poly(lactide-co-glycolide) (PLGA) polymer, the lactic and glycolic units in Poly(lactide-alt-glycolide) alternate in sequence in the polymer chain, and the molar ratio of lactic to glycolic units in the polymer is exactly 1:1. Poly(lactide-alt-glycolide) exhibits excellent solubility in common organic solvents, such as acetonitrile, acetone, dioxane, DCM, and THF, providing great convenience for drug delivery researches and applications.
Common Poly(lactide-co-glycolide) (PLGA) is a biocompatible and biodegradable polymer that has been approved by the FDA for biomedical and pharmaceutical applications. PLGA based polymers are usually synthesized from copolymerization of glycolide (GA) and lactide (LA). However, the copolymerization of glycolide (GA) and Lactide (LA) typically results in broad composition ranges and a random block nature because of the much higher reactivity of GA and the drastic polymerization conditions. Thus, simple use of equimolar charges of GA and LA results in polymers containing longer glycolic blocks leads to poor solubility in common solvents.
