Abstract
A temperature-responsive synthetic vinyl polymer with hydrogen-bonding and hydrophobic side residues, poly(N-vinylisobutyramide) (PNVIBA), was studied for its calorimetric properties in aqueous solutions. The temperature-responsive behavior was dependent on the polymer concentration at lower range and also on the concentration of added sodium dodecyl sulfate (SDS) at higher range. Thermodynamic parameters and molecular weight dependence were discussed in comparison with the corresponding results from poly(N-isopropylacrylamide) (PNIPAM).
