Swelling Behavior of Cross-link PVA with Glutaraldehyde	2017	11	.pdf	application/pdf	2700	147	66	Figures (3.10) to (3.12) show the difference in swelling at equilibrium at pH 1.2, 4.7, 6.8 at 37 °C for cross-linked PVA hydrogels prepared with varying degree of GA. effect of cross-linking concentration on the swelling properties of PVA hydrogel is shown in Figures (3,4) to (3.6) .As this figure indicates different ratios of GA / PVA show significant difference in their water uptake qualities P< 0.05 change entanglement a long with increase in cross-linking agent concentration would result in a decreased network expansion lower GA /PVA ratio cause a significant increase in swelling properties P<0.05 .In general, it may be concluded that by increase in the GA /PVA ratio, the cross-linking density increases and this in turn reduces the swelling or water uptake of the gels significantly .	cache/iajs-218.pdf	txt/iajs-218.txt
