Epitaxial crystallization of polyethylene on organic substrates: A reappraisal of the mode of action of selected nucleating agents
Abstract
Electron microscopy and electron diffraction studies show that polyethylene crystallizes epitaxially onto crystals of homologous series of (i) condensed aromatic hydrocarbons and (ii) linear polyphenyls. The contact planes of the PE chain‐folded lamellae with the (001) faces of the substrate crystals are found to differ for the two series, being (100) and (110), respectively. The underlying epitaxial relationships are best explained by a two‐dimensional lattice matching of polymer and substrate networks. In view of the structural similarities of the present substrates and some well‐known nucleating agents for polyethylene, epitaxy is suggested as a possible mechanism which could explain the nucleating ability of the latter. This is experimentally demonstrated with the potassium salt of phthalic acid.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
