50—THE RELATION BETWEEN INTRINSIC VISCOSITY AND DEGREE OF POLYMERIZATION FOR CELLULOSE AND ITS PRINCIPAL DERIVATIVES

R. J. E. Cumberbirch, W. G. Harland

Open publisher page 19 citations

Abstract

The relation between intrinsic viscosity and degree of polymerization has been established for cellulose in cuprammonium, and cellulose triacetate in methylene chloride/ethanol mixture. The relation for cellulose was derived by two independent routes and good agreement obtained. Tables are given in an appendix whereby degrees of polymerization can be determined directly from cuprammonium fluidity measurements made at cellulose concentrations of 2 g/100 ml and 0·5 g/100 ml.
