Melt blending of different polymer species normally produces weak interfaces due to their entropic penalty of mixing.Block copolymers containing dissimilar types of monomers can be used to tail the properties of immiscible polymer interfaces.One of the most important methods for introducing copolymers to the interface is reactive blending, i.e. the in-situ formation of block copolymers at the interface.Compared to simple admixing of copolymers, chemical reactions generate stronger interfaces and more effectively enhance mechanical blending of thermodynamically incompatible polymer species.A large body of literature has so far been focused on the effect of reactive polymers on morphology and adhesion.Although the structure of the reactive polymer and its reaction kinetics are crucial to understand the interfacial properties, surprisingly little has been investigated about them.
