Results showed that the co-PP chains promoted crystal refinement, and the rubbery phases corresponding to the propylene–ethylene random segments offered superior toughness. This proves that crystal morphology, which correlates with β-NA content, is another important factor that determines toughness and tensile strength in addition to β crystal content. Furthermore, a mechanism for the morphology evolution is proposed. This study shows the feasibility of improving the mechanical properties of iPP and expanding its applications.","claims":[{"public_id":"cl_93ca0969a2ce776f6939a8a04fc96fc8","status":"active","text":"A
