| Abstract: | This article mainly reviewed the advancement of polymer crystallization behavior under stress field,it summarized the influence of the various kinds of stress (shearing,tensiling, vibrating) on the crystal morphology of polymer and crystallization kinetics.It discussed that how the nucleation of polymer and crystal growth individually depend on the shear rate,shear form,molecular weight and its distribution,and that the existence of stress field benefits the nucleation and crystal growth.It also summarized the effects of tension and vibration on polymer crystallization. |
