Rheological measurements indicated thermothickening behavior for the 50 % PNIPAM–50 % CMC physical blend in aqueous solution, at 6 g/L, as viscosity rose when temperature was increased to a range of 25–40 °C. Similar thermothickening behavior was observed for the 25 % CMC–75 % PNIPAM physical blend in solution, at a total polymer concentration of 2 g/L. These results provide new information for preparing physical blends in aqueous solutions exhibiting thermothickening behavior, indicating that this behavior depends on total polymer concentration and composition of the mixture.Submitted by Edileide Reis (leyde-landy@hotmail.com) on 2014-04-22T12:30:14Z No. of bitstreams: 1 Rosangela R.
