| Abstract: | The viscosity behavior of collagen, chitosan and their blends at several compositions (2/8, 4/6, 5/5, 6/4, 8/2) has been studied. The miscibility of this polymer system was investigated on the basis of the sign of the criteria ΔB, Δb, Δη], α and β determined by dilute solution viscosity. These investigations indicate that collagen/chitosan is miscible at any composition in HAc at 25 °C. According to the “memory effect”, we can conclude that collagen/chitosan is also miscible in the solid state. |
