TLDR
In this article, a broad range of degrees of crosslinking, from 1.7 up to 74% of reacted hydroxyl groups, was achieved, and the variation of the thermal and mechanical properties of PVA with the crosslink density show an initial decrease due to the diminution of the crystallinity of the system, caused by the cross-linking.About:

Effect of the morphology of hydrophilic polymeric matrices on the diffusion and release of water soluble drugs
TL;DR: In this article, drug release mechanisms from, and diffusion processes in hydrophilic crosslinked polymeric systems were investigated in two macromolecular states: in the glassy and rubbery states during the early part of countercurrent water diffusion, and in the rubbery state after thermodynamic equilibrium between the network and the surrounding dissolution medium (water) was attained.
