A computer program has been devised for routine use which processes raw data such as polymer sample weight, moisture content, solution volume, and viscometer flow times to calculate a least‐squares‐derived intrinsic viscosity. In addition to eliminating errors inherent in graphic solutions and freeing technicians from tedious calculation, the computer output provides the 95% confidence interval of the intrinsic viscosity.
