This case study deals with relationships between characteristic properties of organic ion-exchange resins and heterogeneous ion-exchange membranes.Membranes were prepared by using different filler/polymer matrix ratio or by using milled resins with different particle size distribution.Different ion-exchange resins were used for preparing of heterogeneous ion-exchange membranes at fixed filler/polymer matrix ratio.It was proved that there are important relationships between properties of a membrane and the type of resin used for its preparation and the process of membrane preparation.The results show that most of ionexchange resins can be used for ion-exchange membranes preparation but with different impact on characteristic properties of membranes.On the basis of these results we are able to modify composition of heterogeneous ionexchange membranes to reach required properties.
