The isothermally crystallized films of the low temperature fractions of the two PPEs possess the similar crystalline morphology, i. e., thinner and high content of cross-hatching lamellae. The main reason to create the different crystallization behavior between the two PPEs and their fractions was due to the different distribution of the copoymerized ethylene unit.

对于分级样品，PPE1和PPE2高温级份的结晶行为差别较大：PPE1的高温级份结晶时形成的片晶较厚并且交叉片晶的数量也较低，剪切时产生较多纤维晶；两个样品的低温级份结晶形态类似，即结晶时形成的交叉片晶的含量都较高，剪切产生纤维晶数量差不多。
