Notes:
The physical properties of a new class of ionomers comprising a semirigid polyphenylene ether backbone were investigated. The material was studied principally in the form of films of ca. 150 μm micrometers in thickness. The study focused on material of 600 equivalent weight. Torsion pendulum results showed a significant increase in the glass transition temperature of the ionomer relative to that of its ester precursor but gave no evidence of ionic clustering. Stress-strain studies performed both in water and in 20% KOH solution at 80°C indicated that the mechanical properties of the material remain stable under these conditions. Differential scanning calorimetry was used to investigate both the high temperature behavior and the water uptake of the ionomer films. The behavior of this ionomer at high temperature and in an alkaline solution is of particular interest in view of the possible use of these films as separators in an alkaline electrolysis cell.
