Dissolution clock

Anomalous Transport and Reptation Anomalous transport, dissolution clock, scaling laws, experiments [59]... 

The concept of the dissolution clock was introduced. Initially, the clock is set to zero at each point in the polymer. The clock measures time only after the solvent concentration at that point reaches a critical value. When the clock time becomes equal to the disentanglement time, the polymer at that point dissolves. This is pictorially shown in Fig. 26.
