Intrinsic viscosity-molecular weight relationship for low molecular weight cellulose and oligosaccharides

The viscosity behaviour of low molecular weight cellulose and oligosaccharides has been investigated. In the high molecular weight region the double-logarithmic plot of intrinsic viscosity vs molecular weight is linear down to approximately DP = 150. On passing to lower molecular weights the slope of the curve at first increases, passes through a maximum and finally decreases to very low values in the oligomere region.
