Experimental Thermodynamics of NiPAM in Water — •Jakub Polak, Daniel Ondo, and Jan Heyda — University of Chemistry and Technology, Prague, Czechia

Unlike for thermoresponsive polymer PNiPAM, the knowledge of thermodynamic properties of aqueous N-isopropylacryl amide (NiPAM) is far from being complete.

In this contribution, the macroscopic thermodynamic properties of aqueous NiPAM are measured and the workflow towards Kirkwood-Buff integrals is presented. Namely, we report the experimental determination of partial molar volumes, osmotic coefficients, and excess partial molar enthalpies of NiPAM in water. These thermodynamic functions are subject to the Kirkwood-Buff inversion procedure. The concentration and temperature dependence of Kirkwood-Buff integrals is discussed and compared to other amides.
