Abstract : The adsorption of krypton and ammonia on the organic solid p-chloranil has been investigated. Isotherms were obtained for krypton at 77.36 K and ammonia at 194 K. The adsorption of krypton is reversible and reproducible. The affinity for ammonia is much higher, irreversible behavior and reduced adsorptive capacity on repeated adsorption being obtained for this system. These results indicate that the adsorption of krypton is pure physical adsorption whereas ammonia is both physically adsorbed and chemisorbed. (Author) An appendix gives details of investigations into polymeric semiconductors: polysulfur nitride, conjugated polymers, and polymer charge transfer complexes.
