The water equilibrium concentration in styrene crosslinked polyesters increases with the temperature; this behaviour has been interpreted in terms of material expansion induced by temperature. We have verified this hypothesis by swelling measurements in water and gravimetric experiments at various temperatures between 30°C and 90°C. Samples were propylene glycol/neopentyl glycol ‐ maleate / isophthalate copolymers crosslinked by styrene.
