Abstract

The absolute values of the Huggins viscometric constant for semirigid- and rigid-chain aromatic polyamides are high, but not very high in comparison to the values for flexible-chain polymers. The Huggins viscometric constant virtually does not change with some, at least two-fold, change in the molecular weight of semirigid- and rigid-chain polyamides, which is similar to the results known for flexible-chain polymers. Either the thermodynamic rigidity of the macromolecules or the thermodynamic affinity between polymer and solvent as a function of the nature of the solvent have the predominant effect on the values of the Huggins viscometric constant in solutions of aromatic polyamides.
