Molecular dynamics simulations are performed to study the diffusion and permeation of gases, including argon, nitrogen, methane, carbon dioxide, and propane, in polystyrene over a wide range of temperatures. A jumping mechanism is observed for the diffusion of diffusants in polymer. The calculated d
Measurements of radius of gyration, (SZ) ~, and persistence length of polymer molecules in bulk atactic polystyrene have been made by means of low angle neutron scattering. The measured values of (S 2 )~ lie close to those measured in 0:solvents and have a molecular weight dependence of M -\*+~ wher
