Investigations reveal flow-induced crystallization impact on isotactic polypropylene, suggesting improved product performance through processing.

The research aims to understand the flow-induced crystallization of isotactic polypropylene with a β-nucleating agent in injection molding.
Utilized a homemade in situ characterization platform for injection molding.
Employed millisecond-scale time-resolved synchrotron X-ray diffraction and scattering techniques (WAXD/SAXS).
Combined ex situ microfocus WAXD and scanning electron microscopy (SEM) for full-path scenario elucidation.
Competitive growth of α-, β-, and γ-crystals observed in iPP/β layers influenced by nucleation barriers.
Shear intensity enhanced early growth of β-crystals but suppressed β-nucleating agent activity.
Ductility showed a positive correlation with β-crystal content, with a notable secondary necking phenomenon.
