Characterization of polyarylamide fibers by inverse gas chromatography.
Two types of commercial polyaramide fibers have been characterized by inverse gas chromatography. Using the fibers as stationary phases, adsorption isotherms for nonane, decane and undecane were obtained. Specific surface areas and isosteric heats of adsorption were also obtained by this method. Experimental results have been discussed as a function of hydrocarbon--fiber interaction and fiber crystallinity.
