abstract = {Controlling the mechanical behavior of novel supramolecular
materials is of the utmost importance and requires a
fundamental understanding of the underlying physical
processes. We present a multimethods approach to the
dynamics of entangled transient polyisoprene networks.
Small-angle neutron scattering (SANS) on randomly
functionalized chains shows homogeneous supramolecular melts
with Gaussian chain conformations. The H-bond lifetimes
(dielectric α*-process) and the rheological response in
terms of the loss modulus G″ differ by 2 orders of
magnitude in time. Within the concept of a compact random
walk (RW), where the random walker (urazole group acting as
a sticker) undergoes multiple returns to its starting point
and following the concept of theoretical proposed
renormalized sticky bond lifetimes, we quantitatively solve
this longstanding and unexplained large discrepancy: While
the bond opening gives rise to the dielectric response, for
rheological relaxation the association with a new partner is
relevant. This takes place only after multiple returns to
the original binding partner.},
