摘要：

Neutron reflectometry is used to study the interface in blends of the partially compatible polymers deuterated polystyrene (PSd) and poly(styrene-co-4-bromo-styrene) (PBr(x)S). The degree of bromination x controls the miscibility of the polymers. It is varied in a wide range in order to obtain information on the dependence of the interface width l on the compatibility of the components as expressed by the Flory Huggins interaction parameter chi. The kinetics of interface formation and the equilibrium values of l and chi as a function of bromination are discussed and compared to current theories.
