✦ Synopsis

The concentration dependence of the skar viscosity of a suspension of qdinders with random flight axes is studied at low concentrations_ The intrinsic viscosity and the Huggins cc&ticient are found to depend on the radius, ~1, of the cylinder only as a series expansion in powers as a2/ZL (I is the Kuhn step Length and L is the contour Iength of the cylinder axis). The Iexiiq terms give identical results to those of Freed-Edwards theory; the zero concentration limit of the leading term reproduces the Kirkwood-Riseman result for a random fiat line disrribution of friction.
