摘要：
The adsorption of a series of commerical polyoxyethylenepolyoxypropylene block copolymers onto polystyrene latex has been studied. Adsorption was Langmuirian in all cases with maximum adsorption occuring after the apparent critical micelle concentration had been reached. Examination of molecular areas at the interface indicate that for high ethylene oxide content surfactants, the hydrophilic chains adsorb as loops. This was confirmed by measurements of the adsorbed layer thickness determined by intensity fluctuation spectroscopy and microelectrophoresis. © 1979 Dr. Dietrich Steinkopff Verlag.
