Abstract
Based on the anionic groups which appear in heparin, sulfonated poly(vinyl alcohol) (S-PVA), and carboxymethylated poly(vinyl alcohol) (C-PVA) were synthesized. Cross-linked blendmer (XSC-PVA)s were obtained by mixing two aqueous solutions of the anionic charged PVA, whose degrees of substitution were 25%, respectively, using glutaraldehyde as the cross-linking agent. These XSC-PVA membranes were prepared under various conditions in order to determine a suitable mixing ratio of S-PVA to C-PVA and concentration of cross-linking agent. Effect of amount of cross-linker on permeability and mechanical property of the membranes was also examined.
