General description
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.
Application
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.

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

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

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
