| Application: | Poly(propylene glycol) can be used: • As a plasticizer as it does not crystalize, has a low glass transition temperature, and is biocompatible. For example, it can be used in the plasticization of polylactic acid. • To prepare the aqueous biphasic system for the recovery of ectoine from Halomonas salina cells. • To study the virtual transition from supramolecular polymer(PPG) toconventional polymer(PPO). |
