Abstract
The intrinsic viscosity of coiling molecules has been calculated using the Kirkwood—Riseman adaptation of the Oseen approximation. Four different models of chain segment distribution were treated: (a) a Gaussian coil, (b) an excluded volume model of Kurata and Yamakawa, (c) a coil expansion model suggested by Peterlin and (d) an excluded volume model deduced from the machine computation of Wall and Erpenbeck. In all cases the partially free draining coil was treated. The mathematical solution of the problem has been carried out on an IBM 704 computer.
