摘要：

The miscibility of chitosan (CS) and starch in buffer solution (CH3COOH and CH3COONa) has been investigated by viscosity, density and refractive index methods at 303K, 313K, and 323K. Various interaction parameters such as polymer-polymer and blend-solvent interaction parameters and heat of mixing have been calculated using viscosity and density data. The results indicated the existence of positive interactions in the blend polymer solutions and that they are miscible below 40% of starch compositions. The study also revealed that variation of temperature does have significant effect on the miscibility of chitosan and starch blends.
