Abstract

The elastic moduli and morphology of block polymers and polyblends can be modified by changing the relative concentration of the components, by heat and solvent treatments, and by the intensity of mechanical mixing. In these two-phase systems the dispersed phase can be spheres, aggregated spheres, or cylindrical or plate-like in shape. Over certain composition ranges, both phases can be continuous, or the phases can become inverted- the dispersed phase can become the continuous phase. These different morphologies have widely different moduli and other mechanical properties. It will be shown that if the morphology of a given block polymer or polyblend is known, then reasonable predictions of the elastic moduli can be made by using the theoretical equations developed for composite materials.
