 | Smith, Grant D.; Borodin, Oleg | Molecular-dynamics simulation study of dielectric relaxation in a 1,4-polybutadiene melt | We have carried out atomistic molecular dynamics simulations of a melt of 1,4-poly(butadiene) from temperatures well above the experimentally observed merging of the primary a process and secondary b process down to temperatures approaching the experimentally observed bifurcation temperature. The re... | Polymer melts; 1,4-polybutadiene; Chain dynamics; Conformational dynamics | 2002 |

 | Smith, Grant D. | On the non-Gaussianity of chain motion in unentangled polymer melts | We have investigated chain dynamics of an unentangled polybutadiene melt via molecular dynamics simulations and neutron spin echo experiments. Good short-time statistics allows for the first experimental confirmation of subdiffusive motion of polymer chains for times less than the Rouse time (T R) c... | Polymer melts; Chain dynamics; 1,4-polybutadiene melts; Neutron spin echo | 2001 |

 | Smith, Grant D. | Prediction of the linear viscoelastic shear modulus of an entangled polybutadiene melt from simulation and theory | While accurate quantum chemistry based potentials,1 improved simulation algorithms, and faster computers have made accurate calculation of chain dynamics in unentangled polymer melts from molecular dynamics simulations possible,2-5 direct calculation of the viscoelastic properties of entangled polym... | Polybutadiene melt; Viscoelastic shear; Chain dynamics; Entangled polymers | 2000 |
