Summary

The viscometric behavior of poly(1-vinyl-2-pyrrolidoneco-maleic acid) samples of different molecular mass values (determined by absolute methods [1,2]) was studied in dilute salt-free aqueous solutions. An f(c)=(ao+a1c)ck type empirical equation was found appropriate to describe the concentration dependence of the specific viscosity. The advantage of the proposed formula over other suggested empirical equations arises from the fact that it involves the relationship valid for uncharged polymers in a limitation case.
