摘要：

The adsorption of random copolymers of ethylene vinyl acetate on modified silica surfaces has been investigated by nuclear magnetic resonance (NMR) spin-spin relaxation, small-angle neutron scattering (SANS) and Monte Carlo (MC) simulations. In particular the effects of polydispersity, molecular weight and composition have been investigated The effect of fmite polydispersity in the chain structure together with specific solvency and surface interactions leads to preferential adsorption. NMR shows that there is a direct correlation between the adsorbed amount and the bound fraction. The average concentration of the adsorbed layers have been obtained by NMR and are in qualitative agreement with SANS. © 1990.
