Microstructure and Phase Separation of Pekk, Pekk and their Blends

MRS Proceedings, 1996
ABSTRACTMicrostructures of PEEK|PEKK blends at both structural and lamellar levels were studied using simultaneously time-resolved small-angle and wide-angle x-ray scattering (SAXS and WAXS) with synchrotron radiations. Lamellar dimensions and unit cell parameters were determined, and phase separation within the blends were observed.
