The dynamics of polymer confined in block copolymer assemblies is addressed. Investigating several block copolymer melts we find a heterogeneous and accelerated dynamics relative to the homo polymer state. We propose a model incorporating self-concentration and interfacial fluctuation effects to describe the data.
