Viscosity of Polymer Solutions is a Macintosh version of a program that was originally developed for the Apple II (1). It is a HyperCard stack that simulates the preparation of polymer solutions using either standard samples or unknowns in various solvents, and gives their time of flow in an Ubbelhode viscometer, along with information relating to the density of the solution as it might be determined with a Westphal balance. Polymer choices include polystyrene in four solvents, polymethylmethacrylate in three solvents, polyisobutylene in two solvents, and polyvinyl alcohol in water at temperatures from 0 to 50 degrees Centigrade. Supplemental features include an animation of the operation of the viscometer, a discussion of the mathematical relationships involved, and directions for operation of the program.
Hardware and Software Requirements Software in Series C of JCE: Software requires an Apple Macintosh computer with a hard drive and a SuperDrive floppy disk drive. Buoyancy Programs, Viscosity of Polymer Solutions, and Precision of Calculated Values all require HyperCard or HyperCard player version 2.0 or higher. At least 2 MB of RAM with System 6 or 4 MB of RAM with System 7 are required. Installation of Buoyancy Programs requires approximately 300 KB of disk space, Viscosity of Polymer Solutions ~ 400 KB, and Precision of Calculated Values ~ 200 KB. Literature Cited |
