Sorption and diffusion in polymer networks prepared from epoxide oligomers

Sorption and diffusion of chloroform vapour in crosslinked epoxide polymers used as protective layers was investigated. The free energy of mixing, diffusion coefficients, and coefficients of self-diffusion have been determined. Self-diffusion coefficient of chloroform in the network increases with the degree of swelling and, for networks in the elastic state, also with decreasing crosslink density.
