Abstract
Small-angle neutron scattering was used to investigate the structure of copolymers adsorbed at the liquid/liquid interface. Both poly(ethylene oxide)/poly(propylene oxide) block copolymers and poly(vinyl alcohol-co-acetate) random copolymers were studied. The emulsions were prepared either by using a technique utilizing aerosols or by using high-speed mixing. The results were analyzed by one of two methods. In one case it was possible to use a direct inversion technique to give the first segment density profile of a polymer adsorbed at the liquid/liquid interface. For the remaining data it was necessary to compare the experimental scattering to theoretical scattering functions, calculated from volume fraction profiles generated using the Scheutjens-Fleer theory of polymer adsorption. These data suggest that rather thick polymer layers are formed.
