Abstract
This support is constituted by a crosslinked polyvinyl alcohol hydrogel, whereof at least part of the --OH groups have been replaced by --OSO.sub.3 H groups. The crosslinked polyvinyl alcohol hydrogel comprises 70 to 95% by weight of chains derived from polyvinyl alcohol and 5 to 30% by weight of chains derived from crosslinking monomers, such as triethylene glycol diacrylate and tetraethylene glycol triacrylate. These supports can be used for the ex-vivo purification of the blood plasma in pocket 31 or 33.
