摘要：

The interactions between sodium dodecyl sulfate (SDS) and dodecyltrimethylammonium bromide (DTAB) with three polymers were studied by fluorescence probing in conjunction with viscometric measurements. Poly(N-isopropylacrylamide), polyacrylamide, and copolymer of acrylamide and N-isopropylacrylamide, were used in the experiment. Neutral polymers interacted with ionic surfactants when they were hydrophobic which was manifested by a lower critical solution temperature behavior. The interaction of neutral hydrophobic polymers with cationic surfactants, weaker than that with anionic surfactants were detected by viscometry.
