Abstract
A general theory for the intrinsic viscosity of any segment distribution with cylindrical symmetry is developed. The theory avoids the substitution of a scalar for the Oseen tensor. Application is made to the wormlike coil and the weakly bending rod. The Flory φ for the random coil calculated by this method is 2.20×1021. The theory is in agreement with the results of Kirkwood and Auer in the limit of the rigid rod.
