Abstract
A new type of highly ordered, microphase-separated polymer material is synthesized by simple ionic coupling of a commercial styrene/ethylene oxide twoblock copolymer with a charged end group to an oppositely ch arged polyelectrolyte by common precipitation from aqueous solution. T he characterization of the polymer/polymer complex by small-angle X-ra y scattering and polarization microscopy reveals that the comb-like ad dition complexes formed by ionic grafting build up a mesophase with la mellar morphology and a periodicity of d = 7.1 nm which is easily orie nted in mechanic fields.
