There are two approaches usually used to determine the intrinsic viscosity () of polyacrylamide. The extrapolation method is much more accurate but inefficient. However the single point method is simple and rapid but too big erroneous. The nomographic technique was introduced to calculate the intrinsic viscosity in this paper, first of all, the curve of were drew through a set of basic data of polyacrylamide, then the of one sample were obtained by the curve. The comparison of nomographic method with extrapolation method and single point one revealed that the nomographic technique is convenient and accurate.
