애플리케이션

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).

The designed DNA sequences can make DNA-b-PPO undergo in situ transition between diblock and triblock upon pH changes, consequently, induce a morphology-shifting from spherical micelles to nanofibers. This process is reversible and the assembled structures have been characterized by CD

The objective of this study was to evaluate and compare in vitro the decalcifying capability on root canal dentin of 4 different irrigating solutions. Twenty-five freshly extracted maxillary central incisors were selected. The canals were prepared to obtain a total

We show here that complementary interactions can suppress mesoscopic order and thus lead to a counterintuitive change in material properties. We present results for telechelic supramolecular polymers based on poly(propylene oxide) (PPO), thymine (Thy), and diaminotriazine (DAT). The self-complementary systems

This study examines the in vitro characteristics of a crosslinking polymer system for cerebral aneurysm embolization. The polymeric material is composed of poly(propylene glycol)diacrylate (PPODA) and pentaerythritol tetrakis(3-mercaptopropionate) (QT), formulated with the liquid contrast agents Conray™ or Omnipaque™ 300.

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
