Chemische Eigenschaften
white to off-white powder
Verwenden
Imidazolium modified PPO with liquid ionic graphene oxide can be used as an anion exchange membrane (AEM) composite with a peak power density of 136 mW cm
?2 for use in the fabrication of high performance fuel cells. It may also be sulfonated to form a long chained polymeric structure with an efficiency of 81.8% at a current density of 120 mA cm
?2 for potentiall use in vanadium redox flow batteries (VRFBs) as effective energy storage systems. It may also be used in the formation of AEMs, which can be used in the development of microbial desalination cell system (MDCS).
synthetische
Oxidative coupling is readily accomplished by passing oxygen into a reaction
mixture containing 2,6-xylenol, pyridine and cuprous chloride. (The molar
ratio of pyridine to cuprous ion is generally in the range 10: 1 to 100: 1.)
External heating is unnecessary; during the course of the reaction the
temperature rises to about 70??C. The polymer is precipitated with dilute
hydrochloric acid and collected by filtration.
It is generally accepted that aryloxy radicals are intermediates in the
polymerization reaction since ESR studies have shown the presence of both
monomeric and polymeric aryloxy radicals in polymerizing solutions of 2,6-
xylenol. The simplest mechanism that can be suggested for the reaction is
aromatic substitution:

Allgemeine Beschreibung
Poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) is an anion exchange membrane (AEM) material that is mainly used as a cross-linker in which the methyl groups are used to bond with ultraviolet (UV) excited ketones.
