Description PEG-PPG-PEG symmetric triblock copolymer constitutes of poly(ethylene oxide)(PEO) and poly (propylene oxide) (PPO). The unique characteristic of PPO block exhibiting hydrophobicity at temperatures above 288K and solubility in water at temperatures below 288K lead to formation of micelle consisting of PEO-PPO-PEO triblock copolymers. Some studies report that the hydrophobic core contains PPO block and a hydrophilic corona is comprised of PEO block. In 30wt% aqueous solution PEG-PPG-PEG forms a cubic gel phase.

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.

Features And Benefits Good biocompatibility;
Properties can be easily modulated by changing the block copolymer segment sizes to suit a particular application.
