Abstract:

This report describes the progress made under the present contract. It is presented in three main sections dealing, respectively, with structure- property relations, with blends, and with block copolymers. In the area of structure-property relations, one paper is particularly noteworthy in that it presents a new model for the morphology of ionomers which is consistent with all known experimental results, including small angle X-ray scattering and mechanical properties, among many others. In the blend area, the most notable result pertains to the achievement of controlled miscibility between nylon and polystyrene. Finally, in the block copolymer area, a completely new two dimensional micelle morphology was discovered at air-water interfaces. These studies represent the highlights of the broad investigation of the effect of coulombic interactions on the properties of polymer in the bulk, in solution, and on surfaces.
