## Abstract In this study, hydrogels were prepared from blends of poly(vinyl alcohol) (PVA) and poly(vinyl pyrrolidone) (PVP). The miscibility of the polymers was confirmed with differential scanning calorimetry with the appearance of a single glassβtransition temperature. Additionally, a negative

Hydrogel blends were prepared from water-soluble polymers of poly(vinyl alcohol~inyl acetate) and poly(vinyl pyrrolidone). The method of preparation was optimized and different compositions of blends were characterized. The effect of thermal treatment and the introduction of an aldehydic crosslinkin
Transparent hydrogels were prepared by blending solutions of poly(vinyl alcohol-vinyl acetate) with either poly(acrylic acid) or poly(vinyl pyrrolidone) in the presence of glutaraldehyde as a crosslinking agent. The network obtained from the poly(vinyl pyrrolidone) system was subjected to various th
