| Popis: | The influence of α-methyl substitutions on the interpolymer complexation between polyisopropylacrylamides (poly(N-isopropylacrylamide) and poly(N-isopropylmethacrylamide)) and polyacrylic acids (poly(acrylic acid) and poly(methacrylic acid)) has been studied. The influence of solvents on the complexation process and, therefore, the effect of polymer–solvent interactions on the complex formation have been analyzed. Specific interactions were analyzed by Fourier transform infrared spectroscopy, and the composition of the obtained complexes was determined by elemental analysis. Finally, the thermal behavior of the obtained interpolymer complexes has been studied by calorimetry and thermogravimetry. |
