Abstract
The main topics dealing with polymer/liquid interactions are the penetration mechanisms (diffusion), the deterioration of the mechanical properties of the polymer, and its dimensional change termed hygroelasticity. The physical implications of the coefficient of hygroelasticity are analogous to those of the coefficient of thermal expansion. The coefficient is sensitive to both the chemical composition and the physical structure of the polymer. In composites, it reflects the type, volume fraction and direction of reinforcement. It also has a role in predicting the lifetime of a polymer failing by crazing or cracking due to swelling.
