Structural studies of poly(aryl ether ether ketone ketone) (PEEKK) using small-angle X-ray scattering and one-dimensional electron density correlation function methods revealed that its aggregated state structure was significantly influenced by the annealing temperature. The long period L, the avera

β¦ Synopsis
The influence of CO 2 laser radiation on the surface properties of poly(ether ether ketone) (PEEK) is shown. The influence on the surface chemistry is nearly negligible, but the roughness increases and the crystallinity in the surface region decreases with increasing laser intensity. The crystallinity of the surface region was determined by a newly developed procedure using photoacoustic infrared spectroscopy.

Physical aging of films of poly(ether ether ketone) kept for 2 months at 120ΠC was studied. The extent of aging was evaluated with different techniques. Aged samples show different thermal behavior and exhibit different mechanical, transport, and viscoelastic properties. An attempt was made to estab
