What is Nanostructure Evolution in Poly(propylene) During Mechanical Testing about?

## Abstract Slow continuous mechanical tests of oriented poly(propylene) (PP) are monitored by combined two‐dimensional (2D) ultra‐small‐angle X‐ray scattering (USAXS) and small‐angle X‐ray scattering (SAXS). Patterns are transformed to the 3D chord distribution (CDF), a real‐space representation of nanostructure. From the CDF, topological parameters of the semicrystalline domain structure are extracted and discussed. A continuous‐strain test shows fracture and release of weak lamellae (2–10% strain). Beyond that we see conversion of lamellae into needles. As all layers are consumed the material breaks. Fatigue is studied in load‐reversal (between 10 and 35% strain). We report cyclic (damped) crystallization, layer break, and relaxation melting. magnified image
