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.

Storage Class Code

11 - Combustible Solids

In this work, a series of biodegradable triblock poly(ethylene glycol)-poly(epsilon-caprolactone)-poly(ethylene glycol) (PEG-PCL-PEG, PECE) copolymers were successfully synthesized by ring-opening copolymerization, and were characterized by (1)H NMR, FT-IR, GPC, and DSC. Aqueous solutions of PECE copolymers underwent thermosensitive sol-gel-sol transition as
