Abstract: Polypropylene is a common used packaging material due to its many advantages, such as low price, light in weight, stable property and so on. But the notable flaw is its brittleness at low temperature. A Poly(ethylene-1-octene) copolymer is chosen as a blend to improve the processing properties of polypropylene. Studies on polymer process should be including not only the complicated structures for the various species but also the influence of external field such as shear on the polymer structures. In this work the crystallization morphology and structure of blend PP/PEcO is investigated through the LLS, TG, POM, WAXD and SR-SAXS techniques. For blend PP/PEcO, it is found that the morphology of sphere crystal obviously changes with the increasing amount of PEcO. Shear induces the orientation of crystallites and lamellae. The differences of shear effect between crystallite and lamellae may support the mesomorphic phase concept of flexible polymer crystallization.
