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 endfunctionality and molecular weight of reactive polymers on the reaction kinetics and the conformation of copolymers formed at the interface due to reaction. This study applied Monte Carlo simulation approach with a parallel processing technique and slithering snake model, which accelerate the simulation rate three times more than that of local hopping model. 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 for the low concentration of reactive 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 static and dynamic interfacial properties significantly depend on the number of endfunctional group, the concentration and the length of reactive polymers.
