Based on several unsymmetrical, twist, noncoplanar phthalazinone-containing monomers 2a–2e and an active bis(4-fluorophenyl)phenyl phosphine oxide (BFPPO) monomer, a series of novel poly(phthalazinone ether phosphine oxide)s (PPEPO) was synthesized by anhydrous K2CO3 mediated N-C coupling reaction in DMAc. The polymers exhibited good thermal proper...

The synthesis, characterization, thermal degradation and stability of polyaniline (PANI), poly(m-nitroaniline), poly(m-chloroaniline) and poly(o-methylaniline) were reported. Different properties were measured and compared with PANI to find out the effect of electron donating groups (−CH3) and electron withdrawing groups (−Cl, t—NO2). It was found ...

The structural changes around a crack tip in a high density polyethylene were investigated by means of scanning synchrotron microfocus small-angle X-ray scattering technique. The scattering data confirm the process of craze structure development near a crack tip based on the evolution of voids. In addition, it was found that the main stress in the ...

Two hypercrosslinked polymeric adsorbents (ZH-01 and Amberlite XAD-4 resin) were employed to remove three kinds of phenolic compounds including phenol, 4-nitrophenol and 2,4-dinitrophenol from aqueous solutions. The study was focused on the static equilibrium adsorption behavior, the column dynamic adsorption and desorption profiles. The Freundlich...
