The molecular motion of amorphous region at high-frequency was found to be hardly affected during the stretching processes. In summary, elongation has created major but different influences on the morphology and molecular motion of the aforementioned four series of polymeric elastomers. For those elastomers like natural rubber and poly , elongation has induced crystallization of the noncrystalline or the soft segments. The crytallinitiy and the crystal thicknesses increase monotonously during the course of the stretching; On the other hand, the stretching processes for those semicrytalline copolymers like EMA and POE are rather complex, including the formation of crystal at relatively low λand the destruction of the crystal at the utmost λ. It revealed that stretching process has resulted in a decreasing of the thicknesses and a shortening of 〓C T〓s for the orthorhombic crystalline components.

拉伸对上述四个弹性体体系的聚集态结构都产生了很大影响，但是影响的程度和内容因体系而不同，对于本身存在着化学交联或者是物理交联的体系而言，拉伸导致了其中本来难以结晶组分的结晶，且结晶度随着拉伸比增加而增加，与此同时，体系结晶的晶片厚度也会逐渐增加；而对于结晶性共聚物体系，如EMA和POE，结晶区本来起到了物理交联的作用，在这种情况下拉伸的影响变得比较复杂，拉伸对于不同晶型的影响有所不同，在拉伸比较低的情况下体系总体的结晶度会有所增加，说明有新的结晶产生，当接近或达到断裂伸长比时，体系的结晶度会突然降低，含量占优的结晶会被拉伸所破坏，含量较低的结晶在整个拉伸过程中受的影响较小。
