✦ Synopsis

The adequacy of the Yamakawa-Fujii theory for description of intrinsic viscosity of rigid chain polymer molecules has been shown for the range of low molecular weights when the number of the Kuhn statistical segments in macromolecules does not exceed 2.28 and the chain is modelled b\ a slightly curved thin rod. The equilibrium rigidities of macromolecules of some rigid chain polymers Ipolyisocyanates, polybenzylglutamates, ladder polysiloxanes) calculated according to this theory are in good quantitative agreement with the rigidities determined by other methods.
