Fund Project: This work was financially supported by the China Postdoctoral Science Foundation (No. 2012M521233), the Fundamental Research Funds for the Central Universities (No. WK2310000031), the National Natural Science Funds for Distinguished Young Scholar (No. 51325301) and 973 program of MOST (No. 2010CB934504).

On the basis of research method in FTIR imaging, we made a heterogeneous thin film of isotactic polypropylene (iPP) that contains a few large spherulites (~150 m) which are surrounded by small spherulites (~15 m) for tensile testing. The evolution processes of crystalline and amorphous orientations of iPP are monitored with its characteristic peaks at 998 and 973 cm-1, respectively. By introducing the correlation images, the analysis demonstrates the relationships between the orientation evolutions of crystalline and amorphous phases in a space of 250 m 250 m detecting area. During the plastic deformation, crystalline orientation is higher than amorphous orientation outside the large spherulite, while that is opposite inside the region. In addition, the evolutions of crystalline and amorphous orientations almost keep a positive correlation.
