Analysis of the conformation of wormlike chains by combination of small‐angle x‐ray and small‐angle neutron scattering

Abstract An analysis of the conformation of a wormlike polymer by small‐angle scattering is presented. By a combined investigation of small‐angle X‐ray and of small‐angle neutron scattering the effect of the finite size of the repeating units can be eliminated. The procedure suggested herein therefore allows to obtain the scattering function for a respective infinitely thin chain. The latter quantity is compared to current models of the scattering function of wormlike chains.
