he viscosity and flow behavior of the concentrated solutions in the formic acid aqueous solution have been studied by using RPX -705 Rheopexy Analyzer under various concentration (1--5g. 100ml )
temperature (25 -45℃ )
pH of solvent (0.63 -2. 16 ) and ionic strength (0. 04 -0.4mol·1-1 NaCl salt). It was discussed that the flow index n and flow activation energy E_r change with polymer concentration and temperature .It has been observed that zero shear viscosity de creases with increasing ionic strength and decreasing pH of solvent.
