The change of rheological properties (e.g. viscosity, relaxation time, die swell, melt elasticity etc.) of thermoplastic elastomeric blends of novel polyvinylidene fluoride and hydrogenated nitrile rubber during the structure development has been discussed by S. Saha and A.K. Bhowmick. During mixing, reduction in the size of rubbery droplets altered the melt elasticity and had a significant effect on both the oscillatory and steady shear rheological properties. The cover image describes the breakup of larger rubber droplets into smaller ones with mixing time (left to right) using transmission electron microscopy (top) and scanning electron microscopy (bottom) (scale bar 1 μm).
