Application

Poly(ethylene glycol)-block-poly(propylene glycol)-block-poly(ethylene glycol) diacrylate (PEG-PPG-PEG) is a bifunctional acrylate-based amphiphilic triblock copolymer, which can be used in applications such as pharmaceutics, biomedical and personal care products. It can also be used in the synthesis of alternating block polyurethanes, which can be potentially used in drug delivery.
