Abstract:A liquid state integral equation theory has been developed to study the thermodynamics and structures of fluids of multiblock polymers both with nonpolar and strongly attracting groups. The physical clustering/aggregation process is probed via the calculation of small and wide angle scattering patterns, real space intermolecular radial distribution functions, and length-scale dependent effective compositions. The dependence of such properties on multiblock architecture, backbone stiffness, composition and block length, relative size of neutral and sticky groups, degree of polymerization, temperature, and solvent (neutral or selective) volume fraction has been investigated via model calculations. Exceptionally sensitive dependence of collective structural properties related to microphase separation on polymer concentration, temperature, and other controllable variable is found. Qualitative and semi-quantitative comparisons with small angle x-ray and neutron scattering experiments on telechelic and multiblock copolymers has also been made.
