Fluorescence probing and size exclusion chromatographic studies of polymer-surfactant interactions (original) (raw)

1999

Abstract

Fluorescence probing and size exclusion chromatographic (SEC) techniques were applied to study complexes formed in several polymer-surfactant systems. Fluorescence probing techniques measure the size, micropolarity and microviscosity of the micellar aggregates bound to the polymer. The use of the time resolved fluorescence quenching technique required writing software for data analysis. Size exclusion chromatography was adapted to measure the size of the overall polymer-surfactant complex. A multiangle laser light scattering detector and a refractometer allowed molecular weight determination without reference to elution volume.
