The Source of Molecular Motion and Flow in Polymers.

Description
Video Clip Lecture #21: describes how conformers interactions are responsible for molecular motions and flow in polymers, below Tg in glasses, and above Tg in melts.

We suggest a new interpretation of linear and non-linear viscoelasticity of polymers based on the Cross-Dual-Phase model that describes the statistics of the conformational changes occuring due to deformation inducing stress.

This lecture is 3 hours long but it can be paused at 3 specific sections.
