Rheological measurements on two uncrosslinked, unfilled synthetic rubbers
article
For two uncrosslinked rubbers (EP and polybutadiene) measurements of viscosity, velocity profiles and flow birefringence in stationary shear flow are compared with dynamic moduli for oscillatory shear in the linear region. At a low temperature (20°C) slip at the wall was sometimes found, but not at higher temperatures (above 70°C). The flow behaviour of the two rubbers at higher temperatures does not differ essentially from that of thermoplastics such as polyethylene or polystyrene. The dynamic shear moduli can give a fair prediction of normal and shear stresses in stationary shear flow. © 1975 Dr. Dietrich Steinkopff Verlag.
