Abstract

We studied the shear-induced phase formation (SIPF) or phase inversion (SIPI) of viscoelastic polybutadiene (LPB)/polyisoprene (HPI) blends by light scattering, microscopy, and rheology. We found a coexisting structure, which is corresponding to **walnut-like** scattering pattern in Fourier-space, by small angle light scattering (SALS) and phase contrast optical microscopy (PCOM) at a fixed composition. A coexisting structure is composed of two different periodic structures: string-like domain and anisotropic domain (butterfly-like pattern in Fourier-space) with small characteristic length scales,
