TL;DR: In this article, the authors carried out 2D X-ray scattering experiments on the blends of linear low-density polyethylene (LLDPE) and isotactic polypropylene (iPP) obtained by dynamic packing injection molding in which the melt was firstly injected into the mold then forced to move repeatedly in a chamber by two pistons that moved reversibly with the same frequency as the solidification progressively occurred from the mold wall to the core part.

TL;DR: In this article, the influence of nonquiescent relaxation of isotactic polypropylene on flow-induced crystallization (FIC) is investigated by a combination of particle tracking velocimeter (PTV) with a cone-plate shearing geometry and synchrotron radiation microbeam wide-angle X-ray diffraction (SR-μWAXD), which is aimed to correlate real flow profile and distribution of crystal orientation.

TL;DR: In this article, the structural and mechanical evolution of polyvinyl alcohol (PVA) induced by uniaxial deformation at different concentrations of boric acid is systematically studied with in-situ synchrotron radiation small-and wide-angle X-ray scattering (SAXS and WAXS).

TL;DR: In this article , a stretching-induced phase transition mechanism of polybutene-1 (PB-1) consisting of form II crystals was investigated in three strain-rate regions (A, B, and C) spanning six orders of magnitude (from 0.005 to 100 s-1).

TL;DR: In this paper, a Brownian dynamics simulation is used to investigate the influences of the interchain interactions on the polymer chain motions in both dilute solutions and melts under steady shear flow.
