The Correlation between segment interaction parameter and interface width of polymer blends

The correlation between the segment interaction parameter and the interface width of incompatible polymer blends can be used to obtain information on the segment interaction of incompatible polymers via an accurate measurement of the narrow interface width by neutron reflectometry. Several model systems are discussed including polystyrene/poly(cyclohexyl acrylate-stat-n-butyl methacrylate), polystyrene/ poly (styrene- stat-p-bromo styrene) and poly styrene/poly(methyl methacrylate).
