Change in conformation of a chiral poly(2-oxazoline) induced by temperature or polarity of the solvent.

DOI

The aim of this experiment is to investigate the change in conformation of a chiral polymer dissolved in hexafluoroisopropanol as the temperature of the system is varied. Circular dichroism measurements imply that the polymer becomes more stretched with decreasing temperature, possibly due to the formation of hydrogen bonds between the solvent and the polymer at lower temperatures. This increased length of polymer with the decrease in temperature will give rise to a change in the radius of gyration and a change in the conformation of the polymer which will be studied by SANS. Besides these measurements also the influence of the polarity of the solvent will be investigated by measuring the polymer in three different solvents at room temperature
