Viscometric behavior of concentrated cellulose acetate solutions

摘要

AbstractThe viscometric behavior of concentrated cellulose acetate solutions in a variety of solvent and mixed solvent systems has been studied. Rapid increases in solution viscosity with increase in cellulose acetate concentration are apparently related to polymer nonsphericity and the tendency of molecules to experience extensive nonhydrodynamic interactions. By employing a well‐defined polymer solution theory in conjunction with an empirically determined calibration curve, accurate predictions of concentrated cellulose acetate solution viscosities are possibl
