甲氧基聚乙二醇-b-聚(L-丙交酯)

Biocompatible, amphiphilic block copolymer composed of a hydrophilic PEG block and a hydrophobic poly(L-lactide) (PLLA) block. These materials have been used in control release and nanoparticle formulation for drug encapsulation and delivery applications. Well-defined materials with varying properties can be prepared by controlling the relative length of each polymer block. Hydroxyl termination allows for facile further chemical modification of these materials.
