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.

Segmented polyurethane (SPU) materials based on different soft-segment component (PPG, PTMO and PBA) and various length of soft-segment (molecular weight of PBA: 500, 700 and 1000) were synthesized in this research. The soft-segment components were synthesized from polyether-polyols (PPG and

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

Bi-soft segmented poly(ester urethane urea) microparticles were prepared and characterized aiming a biomedical application. Two different formulations were developed, using poly(propylene glycol), tolylene 2,4-diisocyanate terminated pre-polymer (TDI) and poly(propylene oxide)-based tri-isocyanated terminated pre-polymer (TI). A second soft segment was included

Tissue engineering approaches are currently being investigated for the restoration of myocardial function in heart failure patients, most commonly by combining cells with a substrate to form myocardial-like constructs (MCs). The final properties of these constructs are dependant on the

TiO(2) pillared clay materials were prepared by montmorillonite (Mt) and acidic solutions of hydrolyzed Ti alkoxides in the presence of high-molecular-weight polyoxypropylene (POP)-backboned di-quaternary salts (POP). The as-prepared materials were characterized by means of XRD, FTIR, TG-DTA, XRF, specific surface
