Viscometry is an easy, accessible, but at the same time significant, analytical method for the characterization of polymers in solution. This laboratory handbook offers clear guidelines and tips for the practical everyday application of viscosimetry, as well as supplying a comprehensive companion for the interpretation of viscosimetric data from simple to complex polymer solutions. It is written with the premise that general knowledge of the broad behavioral spectrum of polymer solutions is of utmost importance for the correct handling of viscometric equipment and the interpretation of data. Originating from the author's experience supervising analytical polymer chemistry lab courses, it shows readers how to tackle many practical examples through detailed examples.
