The medium infrared region (4000-400cm-1) has been widely used to study crystallinity because differences could be observed in the vibrational spectrum of several polymers which could be related to crystallinity as determined by X-ray diffraction, differential scanning calorimetry and density measurements. However, as crystallinity is concerned with packing of chains and interactions between neighboor chains, the absorption bands arising from such vibrations appear therefore at wavenumbers below 400 cm -1. Poly-(oxy-1,4-phenyleneoxy-1,4-phenylenecarbonyl-1,4-phenylene) or poly(aryl ether ether ketone) (PEEK),commercially introduced by ICI1, has been attracting increasing interest. It is a semicrystalline polymer with an unusual combination of properties such as high chemical resistance, excellent thermal stability as good mechanical properties. Taking into account of its high temperature high strength characteristics and melt processability, PEEK is generating interest for applications such as reinforced composites, coatings, electrical connectors, impeller housings... Fourier transform infrared spectroscopy is a quick and powerful tool to investigate orientation and/or crystallinity in polymeric materials.
