The electrical conductivity of solution-grown poly (2,6-dimethyl-1,4-phenylene oxide) (PPO) films doped with TCNQ, TCNE, TNF, and I, has been studied as a function of dopant concentration, temperature (298-353 K ) , and field (50-2000 V ) . PPO forms a conductive complex on doping with these strong

Poly(2,6-dimethyl-1,4 -phenylene oxide) (PPO) is a chemically resistant polymer and, therefore, an attractive material for the formation of membranes. However, membranes of unmodified PPO prepared by an immersion precipitation possess very low hydraulic permeabilities at the filtration processes. T
Electrical properties of poly (2,6-dimethyl-1,4-phenylene oxide) (PPO) have been studied by measuring thermally stimulated discharge currents. Depolarization behavior of poled PPO film exhibits temperature-and time-dependent single relaxation around 468 K which is attributed to dipole reorientation.
The thermal degradation and kinetics of poly(2,6-dimethylphenylene oxide) (PPO) were studied by high-resolution thermogravimetry. The thermogravimetry measurements were conducted at an initial heating rate of 50ยฐC min ฯช1 , resolution 4.0, and sensitivity 1.0 in both nitrogen and air from room temper
