Diffusion of polystyrene micronetwork spheres in melts of polyvinylmethylether
We have determined by forced Rayleigh scattering the diffusion coefficients of photo-labeled polystyrene micronetwork spheres (radii ≤ 10 nm) in melts of linear polyvinylmethylether (Mw ≤ 40 000 g/mol) at temperatures of 20−80°C. An expected slippage of the spheres through the meshes of the entanglement network appears possible but is still within the experimental uncertainty of our results.
