Interdiffusion of solvent into glassy polymer films: A molecular dynamics study
Tsige, Mesfin T.; Grest, Gary S.
The effect of polymer-polymer and solvent-polymer interactions on the behavior of the interdiffusion of a solvent in to an entangled polymer matrix was studied. The state of the polymer was changed from melt to glassy by varying polymer-polymer interaction. From simulation of equilibrated solvent-polymer solution, it was found that the glassy system with Berthelot's rule applied for the cross term is immiscible except in the dilute limit. Increasing the solvent-polymer interaction enhanced the solubility of the system without changing the nature of the diffusion process.
