green as the indicator. the same sample after complete conversion to either the hydrogen or sodiunl form was equilibrated with solutions containing 0.1 n sodium chloride and 0.1 n hydrochloric acid solutions in various proportions. after equilibrium had been attained, the solution was analyzed for sodium chloride by evaporation and for hydrocl~loricacid by titration. the resin sample was drained by suction, thoroughly rinsed, and the hydrogen ion on the resin determinecl as in the capacity determinations. the sodium ion on the resin was calculatecl fro111 the difference between the hydrogen ion on the resin and the capacity. in all cases equilibriunl quotient values were obtained using resin initially in the hydrogen form and also using resin initially in the sodillin form. equilibrium quotients were also determined in a similar way on a sample of this butyl ester resin which had been sulphonated by treatment with sulphuric acid to a capacity of 4.67 mgm. equiv. per gm. ion exchange membranes one of the major difficulties encountered in the preparation of unsupported "homogeneous" ion exchange nlenlbranes by the sulphonation of polystyrene films is the low tensile strengths which the products possess. the copolymerization of ester monomers with divinylbenzene permits the preparation of resins which because of low capacity have much less tendency to swell. for example, such films prepared by the copolymerization of n propyl p vinylbenzenesulphonate with divinylbenzene had the following characteristics:
