摘要：
The relationships between polymer structure and water diffusivity have been investigated in four structural series: amine-epoxyde networks (A), aromatic polysulfones (B), styrene crosslinked polyesters or vinylesters (C) and polyethylenes containing polar groups (D). In each family, it appears water diffusivity is almost inversely proportional to equilibrium water concentration. This result indicates that water diffusion is considerably slowed down by its interactions with polar sites in the polymer.
