Description This product is a special polymer prepared by linking methoxy poly(ethylene glycol) and poly(D,L-lactide) segments together.

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.

Features And Benefits Good biocompatibility;
Properties can be easily modulated by changing the block copolymer segment sizes to suit a particular application.
