Entropy elasticity in poly(2‐hydroxyethyl methacrylate) gels

Journal of Polymer Science: Polymer Letters Edition, 1977
It has been reported that the water-swollen crosslinked poly(2-hydroxyethyl methacrylate) (PHEMA) gel displays an increase of entropy on extension at constant volume in a simple tensile experiment. In this paper, the authors report a new technique for measuring the entropy contribution to tensile load in a solvated polymer. Samples immersed in water at
