Abstract
In this paper we have carried out molecular dynamics simulations (MD) for model systems of liquid n-alkane oligomers (C12~C80) at high temperatures (~2300 K) in a canonical ensemble to calculate viscosity η, selfdiffusion constants D, and monomeric friction constant ζ. We found that the long chains of these n-alkanes at high temperatures show an abnormality in density and in monomeric friction constant. The behavior of both activation energies, Eη and ED, and the mass and temperature dependence of η, D, and ζ are discussed.
