In both situations, a slowing down of the dynamics with respect to the bulk behavior is only observed at intermediate times. The results at long times provide a direct microscopic measurement of the entanglement distance under confinement. They constitute the first experimental microscopic evidence of the dilution of the total entanglement density in a polymer melt under strong confinement, a phenomenon that so far was hypothesized on the basis of various macroscopic observations.MAT2007-63681, IT-436-07 (GV), the MEyC (CSD2006-53), Grants FPU AP2005-1063 and MAT2008-1073.Peer reviewedAmerican Physical SocietyDonostia International Physics CenterMinisterio de Educación y Ciencia (España)Consejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]201220122010info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501http://hdl.handle.net/10261/44242reponame:DIGITAL.CSIC.
