Descriptor of both domain structures and bridge chain network in a thermoplastic elastomer using graph

The ABA triblock copolymer take micro-phase separated structure, and ABA chains take bridge or loop chains. In the elongation process, the coalescences and breaks of domains occurs and the conformations of ABA chains are also changed. To describe the structures of both domains and chain conformations, the simple descriptor for thermoplastic elastomer using graph theory is proposed. We performed the coarse-grained molecular dynamics simulation based on the TPE model by Aoyagi et al, and analyzed these structures using graph.
