Hydrogels based on chemically modified poly ( vinyl alcohol ) ( PVA-GMA ) and PVA-GMA / chondroitin sulfate : Preparation and characterization

This work reports the preparation of hydrogels based on PVA-GMA, PVA-GMA is poly(vinyl alcohol) (PVA) functionalized with vinyl groups from glycidyl methacrylate (GMA), and on PVA-GMA with different content of chondroitin sulfate (CS). The degrees of swelling of PVA-GMA and PVA-GMA/CS hydrogels were evaluated in distilled water and the swelling kinetics was… CONTINUE READING
