S. M. King* ISIS Facility, Rutherford Appleton Laboratory, Chilton, Didcot, Oxon OX11 0QX, U.K. Received February 3, 1997. In Final Form: May 30, 1997X We have used small-angle neutron scattering to study the detailed structure of the poly(ethylene oxide)poly(propylene oxide)-poly(ethylene oxide) (PEO-PPO-PEO) block copolymer Poloxamer 188 adsorbed at the interface in a perfluorodecalin in water emulsion and specifically to investigate the effect of electrolytes and of temperature.
