The steady-state viscosity of a number of cis-polybutadienes was determined aa a function of shear rate and temperature by use of a capillary rheometer. Polymera investigated differed in molecular weight distribution and long chain branching. None of the polymers exhibited Newtonian behavior, even a

An investigation has been carried out into the effect of the fractional composition on the rheological (flow and elastic) properties of a system, using mixtures of polybutadienes with narrow molecularweight distribution (MWD). For mixtures of high-molecular-weight components, the initial Newtonian v
This paper contains results on electrical conduction in 1,4-cis-polybutadiene. Measurements were performed for thin films of thickness from 1 to 10 Ο m with gold and aluminium electrodes. Study was made in the temperature range from 15 to 325 K for two types of polybutadienes: (1) containing 100% of
