Cooperativity of monomer motion within the tube confinement of highly entangled melts.
Scrutinizing the usually ignored short time regime of presently available NSE data from reptating polymers that were collected during the last 3 decades reveals that at short times and distances the dynamics significantly deviates from an expected Rouse dynamics on the entanglement blob level. The presently known experiments focused on long time plateaus and only contain limited data of limited accuracy and sampling density in this regime. In this proposal the best suitable available polymer (PDMS) is chosen to explore the dynamics details in this regime to understand the dynamic peculiarities of reptating polymers that occur at displacements around the tube dimension. 5 days of IN15 beamtime is requested.
