19. Apparent minimal viscosity — molecular weight dependence of anisotropic poly(n-hexylisocyanate) solutions

Summary

It is shown that the inverse velocity of a fallingball in, or ηm the apparent minimum viscosity of, anisotropic solutions of poly(n-hexylisocyanate) in toluene, are molecular weight dependent. The molecular weight dependence follows two linear branches. Below Mw=42600 the apparent minimum viscosity is very weakly dependent on Mw. Above Mw=42600 the apparent minimum viscosity of the anisotropic solution is strongly dependent on the molecular weight.
