The effect of shear rate on the viscosity of polymethylmethacrylate in benzene was studied at 25℃ by means of an Ubbelohde dilution viscometer under external hydrostatic pressure. Four fractionated and one unfractionated samples having molecular weights ranging from 4×10~5-5×10~6 were used for measurement. The maximum shear rate at the capillary wall varied in the range 500-8000 sec~(-1).

The effect of shear rate on the viscosity of polymethylmethacrylate in benzene was studied at 25℃ by means of an Ubbelohde dilution viscometer under external hydrostatic pressure. Four fractionated and one unfractionated samples having molecular weights ranging from 4×10~5-5×10~6 were used for measurement. The maximum shear rate at the capillary wall varied in the range 500-8000 sec~(-1). We treated our experimental data by a power law rheological function, from which the polymer solutions show non- Newtonian behavior, except one sample having lowest molecular weight (M=4×10~5). Flow curves were also deduced directly from the efflux times according to the theory of Weisenberg. For the non-Newtonian polymer solution, the relative viscosity η_r~t is defined as the ratio of the maximum shear rate D_R of the Newtonian solvent to that of the non-Newtonian solution under the same maximum shear stress S_R. The values of η_r~t so obtained show that the extrapolation of ln η_r~t or other functions of η_r~t toward D_R→0 is not practical, because the data deviate more from the linear extrapolation when D_R gets smaller. Two definitions of intrinsic viscosity for the non-Newtonian polymer solution were considered: (1) For a given value of D_R, (?); (2) for a given value of (?). These two definitions become identical for a Newtonian solution. Our experimental data show that, at given D_R, lnη_r~l/C plots are linear, while (η_r~l-1)/C plots are curved; at given S_R, both (lnη_r~l /C)-C and ((η_r~l-1)/C)-C plots are linear and give the same intercept on extrapolation to zero concentration. The values of [η]_D and [η]_s decrease with increasing D_R or S_R, and the change is more pronounced at low values of D_R or S_R, so that neither the extrapolation of [η]_D toward D_R→0 nor that of [η]_s toward S_R→0 is practical. In such cases, we propose the use of [η]_D at D_R=3000 sec~(-1) or [η]s at S_R = 25 dyne/cm~2 for the viscometric molecular weight determination of the polymer.

The molecular weights of nine fractionated samples of butadiene-styrene copolymer were determined osmometrically in toluene at 25°. Experimental technique for the use of osmometer and the swelling of cellophane membrane in 5—30 pct NaOH solutions have been described. The change of permeability during repeated use of the membrane and its possible deformation during a determination were discussed.π/C vs C plots for the system studied are non-linear, while the experimental data permitted linear extrapolation on (π/C)~(1/2) vs C plots to give M_n and A_2 values. The ratio A_2M_n/[η] was found to be a constant, independent of M_n.The[η]-M relation obtained is [η]=1.25×10~(-4)M~(0.78)dl/g in toluene at 30°. The somewhat higher value of a obtained is explained by the fact that previous workers applied linear extrapolation on π/C vs C plots and the possible branching of the samples used was neglected.
