Transition parameters of hydrogels determined during heating by gravimetric deswelling experiments: enthalpy ΔH_grav, entropy ΔS_grav, initial swelling ratio of sample α = m’(T₀)/m_dry, ratio of permanently bound water to mass of dry network β = m_pbw/m_dry, ratio of mass of permanently bound water to total mass of water γ = m_pbw/m₀, onset transition temperature $T_{\mathrm{grav}}^{\mathrm{on}}$ and width of transition $\Delta T_{\mathrm{grav}}$.
