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) polyethylenes containing polar groups (D). In each family, it appears is almost inversely proportional to equilibrium concentration. This result indicates that diffusion considerably slowed down by its interactions with sites the polymer.
