A description is given of recent efforts on the preparation and characterization of a new field of engineering thermoplastics, poly(arylene ether phosphine oxide)s (PEPO). The synthesis and characterization of these materials, in terms of solubility, viscometry, mechanical, thermal and electrical properties, will be discussed. The polymerization proceeded smoothly under conditions previously found suitable in our laboratory for the synthesis of other PAE systems. Upon isolation and purification of the fibrous materials, the structure of the polymers was confirmed by spectral analysis. Infrared spectra revealed the phosphine oxide stretch at 1244 cm-1 and the aromatic ether stretch at around 1230 cm-1.
