Polymer melt relaxation times

The measured relaxation times ﬁt with an exponential decay as expected for a polymer melt.

PEO polymer melt relaxation times at 140 C as measured by Time-of-Flight Neutron Spin Echo (TOF NSE) at one single detector position. Note the large dynamical range in relaxation times.
