Epitaxial Crystallization of Linear Polyethylene in Blends with Isotactic Polypropylene

“…When LPE epitaxially crystallizes on an iPP substrate the zigzag LPE chains are at 50° angles to the c-axial direction of the iPP crystal lattice. This fact is often explained by the interaction of LPE chains with rows of methyl groups that are situated on the (010) plane of iPP -crystals surfaces since LPE chains can fit well into valleys formed by the methyl groups of iPP [1][2][3][4][5][6][7][8][9][10][11][12][13]. However, we know of only a few reports on the epitaxial growth of LPE on uniaxially oriented iPP [14][15][16].…”

“…Heterogeneous epitaxial crystallization, as a specific nucleation event between different polymer or substrate pairs, is still attracting much attention [1][2][3][4][5][6][7], especially for incompatible polymer systems [8,9]. E.g., linear polyethylene (LPE) and isotactic polypropylene (iPP) blends have been investigated intensively [4][5][6][7].…”

Epitaxial nucleation of crystallization at polymer–filler interfaces

“…The increase in temperature of crystallization with the presence of a nucleating agent has also not been satisfactorily explained. Interaction of polymer with a substrate was first reported by Willems (1958), who observed alignment of polyethylene molecules along a sodium chloride crystallographic plane. Similar observation on synthetic and biological polymers have been interpreted as epitaxial nucleation, e.g.…”

Effect of 6-Dioctylamino-1,3,5-triazine-2,4-dithiol Concentration on the Polymer Plating on Iron Plates

“…Nano-scale organic thin films of polymer/metal assemblies have become of interest in a range of potential applications, including decorative electrodes, 1 corrosion protection, 2,3 microelectronics, 4,5 releasing properties 6 and molecular adhesion promoters. 7,8 Some applications require the formation of nano-scale polymer films which are highly aligned and closely packed on metal surfaces. …”

[2][3][4][5][6] The authors have developed effective surface finishing technology that improves various surface characteristics through polymer plating of 6-substituted-1,3,5-triazine-2,4-dithiols (triazine dithiols).…”
