Study on the Interaction of Copolymers SMA and SSMA with Polyoxyethylene Alkyl Ether Surfactant by Fluorescent Method

The combination of fluorescence spectroscopy and traditional surface tension method is used to investigate the interaction of hydrosoluble copolymer SMA and SSMA with polyoxyethylene alkyl ether surfactant.Results show that the interaction effect is related to the adduct number of polyoxyethylene in surfactants and the properties of salt forming metallic ions.Increasing adduct number of polyoxyethylene strengthens the interaction.The salt forming NH + 4 ion is weaker than Na + ion in the interaction.
