METHOD AND DEVICE FOR DETERMINATION OF RHEOLOGICAL CHARACTERISTICS OF POLYMER AND DISPERSE SYSTEMS ABSTRACT A method for determination of rheological charac- teristics of polymer and disperse systems, realized by a device, comprises the steps of placing a system to be investigated into a gap between two coaxial cylinders, the first cylinder being rigidly secured of the case of the device, while the second cylinder is rigidly con- nected to an output shaft of a servo drive, subjecting said system to mechanical deformation by tangentially displacing one of the cylinders in relation to the other in condition of the restricted shear flow of the system, and exposing the system to an electrical field produced in the gap by connecting a voltage source to the external cylinder provided with butt ends transparent for radiation. The specified deformation and double refraction of the system are measured to determined thereby the rheological characteristics of the system being investigated.
