Structure of reactive polymers and reaction kinetics are important factor in analysis of both dynamic and static interfacial properties. We focused on the effects of functionality and molecular weight of reactive polymers on the reaction kinetics and the conformation of copolymers formed at the interface due to reaction. The copolymer coverage at the interface, defined as the number of reacted groups in the reactive polymers per interfacial area, for di-end functional polymers is about twice higher than that for mono-end functional polymers supporting the effectiveness of multiple reaction sites in a polymer. However, it was found that the copolymer coverage rate for longer chain systems is much slower than that for shorter chain systems, which lead to sharper interface for the longer chain system. The interfacial properties including the interfacial width significantly depend on the number of endfunctional groups and the length of reactive polmers. In addition, we also investigate the effects of reactive polymer concentration and molecular weight on interfacial properties like interfacial width and interfacial tension in view of reaction rate.
