Abstract
Incipient micellization in a model self-associating telechelic polymer solution results in a network with a transient elastic response that decays by a two-step relaxation: the first is due to a heterogeneous jump-diffusion process involving entrapment of end-groups within well-defined clusters and this is followed by rapid diffusion to neighboring clusters and a decay ( terminal relaxation) due to cluster disintegration. The viscoelastic response of the solution manifests characteristics of both a glass transition and an entangled polymer network.Keywords
