Study on the Interaction of Copolymers with Surfactants by Flurorescent Probe

The combination of fluorescence spectroscopy and traditional surface tensionmethod are used to investigate the interaction of hydrosoluble copolymers SMA and SSMAwith surfactants SDS,DE_9.Results show great synergistic effects of SSMA-anionic mixturesystem,The surface activity can be increased greatly by adding only 0.1%of SSMA to anion-ic solution. The synergism of SMA with above surfactants is weaker than SSMA.
