The viscosity data of a low temperature Buna-S rubber fraction(M=1.0×10~6)have been determined at 25.0℃ at five concentrations in the range of shear ratesD=10—20,000 sec~(-1).The viscometer used was designed after Tsuda with a horizon-tal efflux volume pipette for flow under low driving pressure.A single capillarywas used for the efflux of solution for the entire range of shear rates in order toget good continuity of data obtained at different ranges of shear rates.The experi-mental results prove definitely the existence of Newtonian flow with relativeviscosities η_r(0)in the range of low shear rates.The values of the Newtonianviscosity η_r(∞)in the region of very high shear rates and the viscosity behaviorin the entire range of shear rates have been estimated from the assumptions thatthe inflexion point D on the Inη_r——ln D curves is independent of concentrationand that the curves are symmetric with respect to their inflexion points.Theequi-shear rate values of lnη_r/C interpolated from the experimental data wereplotted against C and linearly extrapolated to C=0 to get[η]_D values.It again shows definitely the exsistence of a constant[η]_0 value in the range of low shearrates.The experimental data in the transition region between two regions of New-tonian flow can be represented equally well by either of the following equations:where(?)k and s are two parameters,being concentration dependent but approaching aconstant value at higher concentrations.The [η]_D/[η]_0-ln D curve falls closely tothe theoretical one calculated for a rigid ellipsoid with an axial ratio between 4and 5.The rotational diffusion coefficient thus obtained is (?)_(rot)=6.6×10~2_(sec)~(-1).Thevalue of molecular weight calculated from (?)_(rot) and [η]_0 according to the methodof Scheraga and Mandelkern is not in aceord with the actual value and hence thepolymer coil of Buna-S could not be considered to be a rigid structure;while goodagreement is obtained for the molecular weight calculated according to the theore-tical formula of Bueche if the value of 1/D is taken as the relaxation time forelastic deformation of the polynier coil under flow.
