The dependence of the shear modulus and of the swelling equilibrium concentration of polyvinylacetate gel homologues in equilibrium with excess isopropyl alcohol is investigated in the temperature range 30≤T≤70°C. At the theta temperature (T=52°C) the volume elastic modulus was also determined and compared with the shear modulus. The results are interpreted in terms of a free‐energy function derived on the basis of the network unfolding hypothesis.
