    Time evolution of interfacial thicknesses between a cyclic polystyrene (c-hPS) / its deuterated counterpart (c-dPS) and a linear polystyrene (1-hPS) / its deuterated counterpart (1-dPS) bilayer films was investigated by dynamic secondary ion mass spectrometry (DSIMS) and neutron reflectivity (NR). The interfacial thickness of (c-hPS/c-dPS) film was significantly larger than that of (1-hPS/1-dPS) film at any given annealing time, indicating that the diffusion constant of c-PS is constantly larger than that of 1-PS. It might be explained that weaker topological constraint comes from the entanglement for the c-PS than for the 1-PS.
