Description

Application

Biocompatible, amphiphilic triblock polymer composed of a hydrophilic, central PEG block and two terminal hydrophobic PCL blocks. These materials have been used in drug delivery applications as well as thermoplastic elastomers. 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.
