Shear-Enhanced Crystallization in Isotactic Polypropylene. 1. Correspondence between in Situ Rheo-Optics and ex Situ Structure Determination
TL;DR: In this paper, the effects of short term shearing on the subsequent crystallization of polydisperse Ziegler−Natta isotactic polypropylene are observed using in situ optical measurements and ex situ microscopy.
Journal ArticleDOI
Investigation of the influence of polyelectrolyte charge density on the growth of multilayer thin films prepared by the layer-by-layer technique
TL;DR: In this paper, the influence of the charge density along a polyelectrolyte chain on the buildup of multilayer films formed by the sequential adsorption of alternating layers of polyanions and polycations was examined.
Journal ArticleDOI
Shear-Enhanced Crystallization in Isotactic Polypropylene. 3. Evidence for a Kinetic Pathway to Nucleation
TL;DR: In this paper, the authors combined in situ rheo-optical techniques with synchrotron wide-angle X-ray diffraction (WAXD) to investigate the oriented crystallization precursors that develop upon strongly shearing an isothermal melt of polydisperse isotactic polypropylene (iPP).
Journal ArticleDOI
Shear-enhanced crystallization in isotactic polypropylenePart 2. Analysis of the formation of the oriented “skin”
Guruswamy Kumaraswamy,Ravi K. Verma,A. M. Issaian,P. Wang,Julia A. Kornfield,F. Yeh,Benjamin S. Hsiao,Robert H. Olley +7 more
TL;DR: Kumaraswamy et al. as discussed by the authors used wide angle X-ray diffraction (WAXD) to follow crystallization in polydisperse isotactic polypropylene during and after a brief interval of shear under isothermal conditions.
Journal ArticleDOI
Recent Advances in Understanding Flow Effects on Polymer Crystallization
TL;DR: In this paper, the role of chain dynamics in the molecular mechanism of shear-enhanced crystallization of polymers has been investigated, and it has been shown that the effect of the long chains is cooperative, greatly enhanced by long chain-long chain overlap.
