Polymer stress relaxation process is mainly manifested in the polymer chainsegment of the movement and rearrangement, as well as bond Angle changes.
聚合物的应力松弛过程主要表现为高分子链段的运动和重排以及键角的改变。

Analysing in the view of molecular kinetic theory, paste flowability is a shift of molecular mass center by the jump of polymer chainsegment, and it affects the mass-transfer directly.
