Glass transition anomalies dynamic heterogeneity

Creep Rate Spectroscopy for a Discrete Analysis of the Glass Transition Anomalies and Dynamic/Compositional Heterogeneity in Complex Polymer... 

Some of these variants of the anomalies may manifest themselves simultaneously in a polymer system, e.g., when the constraining effect prevails for some segments, whereas the confinement effect is more pronounced for the other segments. The strong dynamic heterogeneity within the glass transition range (variable Q) may be observed in cases III-VI. 

Dynamics over the extended relaxation region III is the impressive example of anomalies in the glass transition. The presented data show the heterogeneous nature of RAF and its origin in high-crystalline polymers. In fact, differently constrained dynamics modes and collapsing of motional cooperativity may be observed simultaneously in this region.
