摘要：

Small-angle neutron scattering (SANS) and nuclear magnetic resonance spectroscopy (NMR) have been used to investigate the structure of terminally attached polymers at the polystyrene latex/water interface. In particular, volume fraction profiles obtained by SANS and by the Scheutjens-Fleer mean-field theory of polymer adsorption were used to calculate spin-spin relaxation functions for the adsorbed layer with different adsorbed polymer coverages and chain lengths. These are compared to the experimentally determined relaxation functions obtained by using NMR. There is a good qualitative agreement with the three approaches. The NMR data provide a new insight into the mobility and structure of the adsorbed layer. © 1990, American Chemical Society. All rights reserved.
