摘要: A stress-controlled commercial rheometer has been equipped with small-angle light scattering (SALS) instrument working in a range of wave-vectors between 0.5 and 4.2 μm−1 By specially designed optical system the scattered is focused directly on square chip CCD-detector high dynamical allowing quantitative two-dimensional (2 D) intensity measurements polarized depolarized scattering. The rheo SALS suited for simultaneous fast 2D rheological material functions polymer melts liquid crystals. As first application results influence shear rate late stage spinodal decomposition polybutadiene/polyisoprene blend are reported. second concerns creep experiment crystalline phase lyotropic non-ionic surfactant measurement time-dependent compliance associated changes patterns
