- Flow Curves of Mixtures of Acrylonitrile-Styrene Copolymers with Different Molecular Weights at Extremely High Shear Rates
抄録
The flow curves of mixtures of acrylonitrile-styrene copolymers with the same S/AN ratio (70/30) and different molecular weights (SAN-1; Mw=1.88×105, SAN-2; Mw=6.5×104) were measured up to the shear rate of 107 s-1. The second Newtonian and the second non-Newtonian region were observed for SAN-1, SAN-2 and their mixtures (<106 s-1) following the first non-Newtonian region. The viscosity decreased with decrease of molecular weight (increase of SAN-2 content) and the gradient of the flow curve (log viscosity vs. log shear rate) of the mixture became smaller with decrease of molecular weight in the first non-Newtonian region. Flow behavior of the mixture was quite different from that of the immiscible polymer blends. The flow curves of SAN with different molecular weights (≥1.28×105) united into one curve at the shear rates higher than 5×105s-1.
