Solid‐state creep, ductility, and drawability are relevant mechanical properties of “crystal‐mobile” polymers, related to a large‐scale chain transport through the crystal, which is in turn mediated by intracrystalline monomer jumps. Here, high‐M_w poly(ethylene oxide) is used as a well‐controlled model system, modulating the properties of the amorphous phase by diluting with a non‐crystallized oligomer. Faster intracrystalline motions are found upon oligomer addition, indicating little changes in the fold surface and a dominant influence of the somewhat reduced lamellar thickness.

低聚物稀释的聚环氧乙烷的晶内动力学

固态蠕变，延展性和可拉伸性是“晶体移动”聚合物的相关机械性能，与通过晶体的大规模链传输有关，而晶体内部的链跃迁又由晶体内单体跳跃介导。在这里，高中号_瓦特聚（环氧乙烷）被用作一个控制良好的模型系统，通过用非结晶的低聚物稀释调制非晶相的性质。加入低聚物后发现更快的晶内运动，这表明折叠表面几乎没有变化，并且是层状厚度略有减少的主要影响。
