Lee, S. K. published the artcileTemperature dependence of the binding of methyl orange by crosslinked poly(4-vinylpyridine), Formula: C10H16N2O2, the main research area is vinylpyridine polymer binding methyl orange; crosslinking vinylpyridine polymer dye binding.
The title polymers with different degrees of crosslinking were prepared by radical copolymerization of 4-vinylpyridine with 3-20% N,N’-tetramethylenebisacrylamide. The binding abilities of these crosslinked polymers with methyl orange were investigated at various temperatures in a buffer solution of pH 7. The first binding constant (K1) and thermodn. parameters were evaluated from the equilibrium amounts of binding. K1 showed bell-shaped curves when plotted against both the binding temperature and the degree of crosslinking. Lower temperature and higher degree of crosslinking at maximum binding in these bell-shaped curves were observed for this binding system when compared with those in a system using N,N’-methylenebisacrylamide as crosslinker. The values of the enthalpy and entropy change increased on increasing the degree of crosslinking and decreasing the binding temperature, whereas the absolute magnitude of the free-energy change was not increased. These results could be accounted for in terms of the temperature dependence of the hole size of the crosslinked polymers in addition to the hydrophobic interactions in the binding process.
