Abstract
Abstract Molecular transport of haloalkanes into polymeric blend sheets of ethylene-propylene random copolymer and isotactic polypropylene, Santoprene, has been investigated gravimetrically in the temperature interval 25°-70°C. Equilibrium sorption, desorption, resorption, redesorption, and degree of penetrant overshoot were influenced by the type of haloalkane used and the experimental temperature. Diffusion coefficients have been computed for the sorption (S), desorption (D), resorption (RS), and redesorption (RD) runs. Temperature-dependent sorption and diffusion coefficients were analyzed using the Arrhenius relation. Santo-prene-haloalkane interactions have been discussed in terms of sorption, desorption, and diffusion coefficients.
