The structure of high-performance polymer blends by small-angle neutron scattering

Abstract Amorphous blends from a deuterated polyaryletherketone and a polyetherimide have been prepared and investigated by small-angle neutron scattering (SANS). The blends are combinatorial mixtures: the scattering quantity Φ1Φ2/S(q) is independant of the composition of the blends.
