Abstract: A Magnetic Resonance Imaging (MRI) experimental system for rheometric study of macromolecule solutions has been set up on a Bruker MSL-400 micro imaging spectrometer. This method depends on a specific accessory to produce the steady-state condition in a "Couette" cell, and a specific pulse sequence to obtain the normal NMR flow velocity imaging. From the imaging data, the relation between the shear stress and shear rate can be obtained easily.

Key words: NMR imaging, Macromolecule solution, Shear stress, Shear rate
