Scattering of multicomponent polymer blends

Abstract The random phase approximation for polymer blends was developed by H. Benoît and described small angle scattering functions as well mean field boundaries. It is a pure theory that loses validity close to the real boundaries due strong fluctuations. However, it gives very clear roadmap about diagrams functions. A simplification of discussed comes into effect when several polymers are mixed involve rather low number chemically different repeat units. Then, correlation same unit pairs can be added up in specific way such overall complexity calculations reduced. within this concept. Graphical abstract
