抄録

Effects of heating and shearing hysteresis on the flow properties, e. g., the nozzle length correction coefficient ν, Barus effect α and shear stress τ-shear rate γ curve in constant pressure extrusion test, for ABS- and AAS-resin, were investigated. ν, α, and viscosity increased with heating and decreased with kneading. Kneading effect index, which was calculated from the change of the nozzle length correction coefficient, was proposed and its usefulness was investigated. This index increased with the increase in temperature and kneading time.<BR>The change of the above-mentioned properties seems to be due to the change of network density in the rubber particles and graft copolymerization ratio between AS copolymer and rubber.
