Transport characteristics of chlorinated hydrocarbon through Nylon/NBR (Acrylonitrile Butadiene Rubber) blend has been investigated with special reference to the effect of blend ratio, compatibilizer and effect of dynamic crosslinking. An attempt has been made to correlate the diffusion characteristics with morphology of the blend. Fine and uniform distribution of the dispersed domains with a stable morphology were obtained by dynamic vulcanization. Depending on the composition, blends show dispersed/matrix and co‐continuous phase morphologies. The various transport parameters such as diffusion coefficient ( D ), permeation coefficient ( P ) and sorption coefficients ( S ) were evaluated at different diffusion conditions such as temperature and percentage of compatibilizer. The equilibrium solvent uptake decreases with an increase in the concentration of NBR in the blends. Finally thermodynamic parameters were evaluated from the diffusion data. POLYM. ENG.
