Flow birefringence and viscometry of dilute acid solutions of polyamid
e and polyester are used for investigations of hydrodynamical, optical
and conformational characteristics of their molecules. Quantative dat
a on the equilibrium rigidity of the molecules are compared with those
obtained before for the molecules with similar structure.
