Kinetic of crystallization from the melt and chain folding in polyethylene fractions revisited: theory and experiment
John D. Hoffman,Robert L. Miller +1 more
TL;DR: In this paper, the rate of growth of chain-folded lamellar crystals from the subcooled melt of polyethylene fractions is treated in terms of surface nucleation theory with the objective of illuminating the origin of the chain folding phenomenon and associated kinetic effects in molecular terms.

Polymer crystallization theories
TL;DR: A review of the various theories of polymer crystallization which have been proposed over the last thirty years can be found in this paper, where the authors provide guidance to the theorist in improving the models as well as to the experimentalist in interpreting his/her data.
Journal ArticleDOI
Hierarchical structure in polymeric materials
TL;DR: It is instructive to consider a hierarchical organization of structure in polymers at four successive levels--the molecular, nano-, micro-, and macrolevels--and to examine how interactions at and between these various levels of structure have important and often quite specific influences.
Journal ArticleDOI
50th Anniversary Perspective: Polymer Crystals and Crystallization: Personal Journeys in a Challenging Research Field
TL;DR: In this paper, the structure and morphology of crystalline polymers has been and remains a major challenge and individual contributions help build a body of knowledge that must cover length scales ranging from submolecular features to morphology and correlate them with bulk properties.

Solution crystallization of polyethylene at high temperatures
S. J. Organ,A. Keller +1 more
TL;DR: In this paper, single polyethylene has been grown from solution in various solvents at temperatures between 70 and 120° C. The crystal thicknesses have been measured by Raman spectroscopy.

Some Theorems on the Free Energies of Crystal Surfaces
TL;DR: In this article, the Wulff construction for the equilibrium shape of a small particle and the relations between atomic models of crystal surfaces and the surface free energy function used in this construction are discussed.

Melting process and the equilibrium melting temperature of polychlorotrifluoroethylene
John D. Hoffman,James J. Weeks +1 more
TL;DR: In this paper, a new method of estimating the equilibrium melting temperature, Tm, of a polymer is described, and applied to polychlorotrifluoroethylene (PCTFE), where the data fit a straight line of positive slope on a Ti (obs) versus Tx plot, Tx being the abscissa.
Journal ArticleDOI
A note on single crystals in polymers: Evidence for a folded chain configuration
TL;DR: In this paper, the morphology and orientation of polyethylene polymers were studied with the electron microscope combined with selected area electron diffraction and it was concluded that the molecules must bend sharply back on themselves forming a regular folded configuration.
Journal ArticleDOI
Theory of Formation of Polymer Crystals with Folded Chains in Dilute Solution.
TL;DR: The theory given for loop nuclei is both general and precise enough at the critical points to suggest that, on crystallization from sufficiently dilute solution, crystals of a definite step height are commonly to be expected for other crystallizable linear polymers than polyethylene, provided loop formation is sterically possible.

Simulation of Crystal Growth with Surface Diffusion
G. H. Gilmer,P. Bennema +1 more
TL;DR: In this paper, a computer simulation model is described which applies to the molecular processes involved in crystal growth under very general growth conditions, and the transition probabilities used for adding and subtracting molecules from the crystal and for surface diffusion are shown to satisfy microscopic reversibility in equilibrium.
