Original language description
Commercially available heterogeneous ion exchange membranes (IEMs) designed for electrodialysis are often based on various types of polyethylene as a polymer matrix. The use of polypropylene (PP) binder for preparation of heterogeneous IEMs is mentioned in literature very poorly. The objective of this paper is to describe preparation of heterogeneous IEMs based on random copolymer of PP (PPR) and characterization of their processability and basic functional properties. Anion exchange membranes (AEMs) were prepared for this purpose with different content and particle size distribution of anion exchange resin and using two different PPR matrixes. The investigated properties of AEMs were water content, dimensional changes according to the temperature, ion exchange capacity, specific resistance, permselectivity and tensile properties. We observed significant differences based on the used matrix in the case of processability and specific resistance, contrary there was only very small influence between permselectivity and PPR matrix. Some of the AEMs possessed better electrochemical properties than commercially available heterogeneous AEMs at lower water content.
