Abstract
The interaction between polyvinyl pyrrolidone (PVP) and two disazo dyes of different chemical composition has been examined from the results of spectrophotometry, con ductometry, and viscosity measurements. The amounts of PVP required for interaction with these dyes depend on the molecular weight of PVP. Changes in the configuration of the PVP molecule due to dye interaction depend on the amount of dye interacted as well as the molecular weight of PVP. The effect of PVP on the interaction between two disazo dyes has also been studied.
