Sd. 36, 447 (1966).] It is interesting to point out that the intrinsic viscosities of the conventional and isotactic PMA samples used in this work, which are difierent in 0.1 N NaCl, were found to be nearly identical in 2 N NaNO, and a = 1 [Pg.361]

Outside the experimental error these data show that, similar to the viscosity result, the pure reptation prediction is violated (i) JV -2.3o o.o5 instead of [Pg.61]

Casson analysis of shear stress s. shear rate for a linear ramp of shear rate with time yields viscosity jvs. shear rate and the Casson "infinite shear rate" viscosity. [Pg.223]

The negative sign is necessary in Equation 9.11 because positive flow (Jv > 0) occurs in the direction of decreasing hydrostatic pressure (dPIdx < 0). The dimensions for the viscosity 07 are pressure x time, e.g., Pa s (the cgs unit, dyne cm-2 s, is termed a poise, which equals 0.1 Pa s) the viscosity of water at 20°C is 1.002 x 10-3 Pa s (values of r w at this and other temperatures are given in Appendix I).

Basic dimensionless parameters. The diffusion and thermal Peclet numbers in the convective mass and heat transfer equations (3.1.8) and (3.1.33) are related to the Reynolds number Re = at/ jv (where v is the kinematic viscosity of the fluid) on the right-hand side in the Navier-Stokes equations (1.1.12) by the formulas [Pg.115]

An approach for improved processing of PMR polyimide is the addition of jV-phenylnadimide to the precursor solution of the monomeric reactants. After the in-situ condensation, a PMR-15 resin is obtained which is diluted with JV-phenylnadimide in order to improve the rheological properties of the system (118). The amount of JV-phenylnadimide (PN) added was in the range of 4 to 20 mol %. Just 4 mol % caused a significant and disproportionate reduction of the minimum viscosity with no concomitant loss of thermal stability. [Pg.207]

The molecular weight of the sodium salt of alginic acid has been determined by measurements of osmotic pressure in sodium chloride solution.88 The n/C versus C curve was found to be independent of salt concentration for values between 0.2 N and 0.5 JV, and the slope of the curve was the same for a series of seven fractions with values of molecular weight between 48,000 and 186,000 (220-860 D-mannuronic acid units). Intrinsic viscosity measurements showed the coefficient a in the modified Staudinger s equation88 to be 1.0 and the approximate value of Km to be 15(10)-4. [Pg.318]
