Application
Biocompatible, amphiphilic block copolymer composed of a hydrophilic PEG block and a hydrophobic Poly(lactide-co-glycolide) (PLGA) block, functionalized with a terminal carboxylic acid. These materials have been used in control release and nanoparticle formulation for drug delivery applications. Well-defined materials with varying properties can be prepared by controlling the relative length of each polymer block. Additionally, the ratio of lactide to glycolide can be tuned to control rate of degradation. Carboxylic acid termination allows for facile further chemical modification of these materials.
