Properties
Description
PCL(5k)-PEG(6k)-PCL(5k) is an amphipathic triblock copolymer containing two hydrophobic polycaprolactone (PCL) blocks and hydrophilic PEG block. The PCL is biodegradable via hydrolysis on the ester bonds.
Molecular Weight
PCL(5 kDa), PEG(6 kDa), PCL(5 kDa)
Identity
Confirmed by NMR.
Applications
PCL(5k)-PEG(6k)-PCL(5k) can be used to construct molecular delivery systems. This triblock copolymer structure modulates the rate of molecular release to achieve long and stable release.
