摘　　要：Interlocked-ring polymers,also known as polycatenanes,possess an interesting molecular architecture.These polymers are composed of many interlocked rings in a linear chain.The topological constrain between neighboring rings distinguishes the interlockedring polymer from its linear counterpart.Here we present extensive molecular dynamic simulations on the interlocked-ring polymers and analyze the static properties of the polymer.By applying external forces to the polymer,we also study the force-extension curves of the polymer,which provides rich information about the mechanical properties of the interlockedring polymers.Interlocked-ring polymers, also known as polycatenanes, possess an interesting molecular architecture.
