[Polymer-containing eye drops. I. Rheological characteristics of polymer solutions].
Authors studied rheological features of opthalmic solutions. They found that water soluble polymer solutions of different characteristics (non-ionic, anionic, linear chain, and/or cross linked) are pseudoplastic in rheological aspect. Rheological features exponentially increase with the concentration of the polymer. With the calculation of the constants of the exponential line, polymer concentration providing an optimum viscosity can be determined.
