Descrizione generale

Poly(propylene glycol) (PPG) is a hydrophobic polyether that is widely used in various biomedical areas such as preparation of biocompatible polyurethanes and lubricious coatings on absorbable sutures.

Applicazioni

Poly(propylene glycol) can be used:
  • As a precursor to synthesize biodegradable poly(ether-ester) networks via UV photopolymerization.
  • As a stabilizing agent in the preparation of metal nanoparticles such as gold nanoparticles.
  • As a starting material to prepare silane-terminatedpoly(urethane-urea)s (SPUR) polymers.

In this work, we proposed a novel aqueous biphasic system (ABS) composed of polypropylene glycol P400 (PPG P400) and hydrophilic ionic liquids (IL), 1-alkyl-3-methylimidazolium bromide (alkyl = ethyl or butyl), forming an upper polymer-rich phase and a lower IL-rich phase

Current treatments for cerebral aneurysms are far from ideal. Platinum coils are prone to compaction, and currently used liquid embolics are delivered with angiotoxic agents. This work presents initial in vivo studies of a novel liquid-to-solid gelling polymer system (PPODA-QT)

The controlled atom transfer radical polymerization of an ionic liquid, 1-(11-acryloylundecyl)-3-methyl imidazolium bromide (ILBr), from both ends of a telechelic poly(propylene oxide) (PPO) macroinitiator, end-functionalized with bromoisobutyryloyl is reported. The resulting highly water-soluble triblock, poly(ILBr-b-PO-b-ILBr) is multistimuli responsive. This new
