The phase transition of perdeuterated thermoresponsive polymers — •Chenrui Ding1, Kuno Schwärzer2, Alfons Schulte3, and Christine M.

The interaction of thermoresponsive polymers with water has been amply studied with respect to the cloud point temperature and the latent heat at the transition, using, among others, turbidimetry and differential scanning calorimetry (DSC) [1]. New information on the polymer-water interaction can be gained using perdeuterated polymers. We present results on poly(N-isopropyl acrylamide) (PNIPAM) and poly(N-isopropyl methacrylamide) (PNIPMAM) and their perdeuterated versions in aqueous solution as a function of polymer concentration and establish the transition behavior.
