VISCOELASTIC PROPERTIES OF SOLUTIONS OF RODLIKE MACROMOLECULES OF FINITE DIAMETER

The intrinsic viscosities, intrinsic rigidities and rotatory diffusion constants have been calculated for solutions of rodlike macromolecules. The results differ from the earlier calculation of Kirkwood and Auer by taking into account the finite cross-section of the rod. In doing this, the parametric dependence of the result on an arbitrary bond length, which was obtained by Kirkwood and Auer, is removed. The general form of the results remains unchanged. The magnitude of the rotatory;diffusion constants and intrinsic viscosities can be used for comparison with experimental data. © 1969, American Chemical Society. All rights reserved.
