rod

Greetings!--The intrinsic viscosity of the  free draining rod has been
approached in at least 2 ways. 1) that of the extreme prolate ellipsoid
(with high length to width) and 2) the use of random coil theory to a
chain of beads, each one of which is the diameter of the rod and can be
individually described by Stokes law. They considered to be rigidly held
in line as in a highly extended highly charged electrolyte. I suspect
that the currently popular "bead" approach would reduce to this latter,
much older approach developed by the polymer physical chemists in the
'50s.  Emory.
