## Abstract Direct determination of the FloryβHuggins interaction parameter Ο of a polymer blend by smallβangle xβray scattering experiments is possible on the basis of the random phase approximation, if absolute intensities are measured. The usually superposed void scattering has to be properly ac
A method is described for the elimination of the intense equatorial maximum due to carbon fibre in the wide angle X-ray diffraction pattern from composite material such as APC-2. A specially prepared sample is required in which the fibres are aligned within the range 45-90 Β° to the specimen surface.
