Synonyms: mPEG-b-PLA; mPEG-PLA
Linear Structural Formula: HO[CH(CH3)COO]m[CH2CH2O]nCH3
Storage: 2-8C
Application: Biocompatible, amphiphilic block copolymer composed of a hydrophilic PEG block and a hydrophobic poly(D,L-lactide) (PLA) 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.
