Device for Simultaneous Measurements of Viscosity and Light Transmittance with Example of Application

Motoki Shibata, Koji Nishida, Tsuyoshi Koga

Abstract

We have developed a device for the simultaneous measurements of viscosity and light transmittance. In general, aqueous solutions of associative polymers often show gelation and/or phase separation. Viscometry and light transmittance have been standard methods in order to evaluate the gelation and phase separation,respectively. However, so far, a unified device to evaluate the both phenomena simultaneously has not been available, although such a device should bring numerous benefits to understanding the mechanism of the gelation and phase separation of aqueous associative polymers. In this study, constitution of the device and several examples of the device are presented.
