The steady-shear and dynamic viscoelastic response at low deformation rates was studied for bcc-forming block copolymer melts and concentrated solutions of various chemistries, architectures, and molecular weights. Polystyrene-polyisoprene and polystyrene-poly(ethylene-alt-propylene) diblock, triblock, and polycrystalline bcc mesophase were considered as samples. Data were explained upon analogies with defect-mediated creep in other solids.
