Synonyms: PCL-PEG-PCL; PCL-PEG-PCL triblock copolymer
Linear Structural Formula: H(OCH2CH2CH2CH2CH2CO)mO(CH2CH2O)n(COCH2CH2CH2CH2CH2O)mH
Storage: 2-8C
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.
