## Abstract Chitosan and poly(vinyl alcohol) blend fibers were prepared by spinning their solution through a viscoseβtype spinneret at 25Β°C into a coagulating bath containing aqueous NaOH and ethanol. The influence of coagulation solution composition on the spinning performance was discussed, and t
## 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
