The paper deals with the surface modification of a heterogeneous cation-exchange membrane with the application for electrodialysis, electrodeionisation, and electrolysis. CM(H)-PP (cation exchange membrane based on polyethylene binder) membrane was covalently attached with poly(divinylbenzene-co-4-vinylbenzylchloride). We have achieved better properties than commercially available heterogeneous ion-exchange membranes in the field of chemical, electrochemical properties by the formation of layer. Ion-exchange capacity was determined with maximum value 2.99 meq g−1 dry matter, area resistance 9.9 Ω cm2 and specific resistance 149 Ω cm, permselectivity 93.4%. [ABSTRACT FROM AUTHOR]

Self-cross-linkable latexes of core–shell microgel particles were synthesized by the emulsion polymerization of acrylic monomers. The molar mass of copolymers forming the shell layer was gradually reduced by isooctyl 3-mercaptopropionate included in the synthesis of the shell layers. The molar mass distribution of latex particles was determined using size exclusion chromatography and asymmetric flow field-flow fractionation, respectively, both separation methods being coupled with a multiangle light scattering detector. The results confirmed theoretical predictions and described empirically the effects of molar mass of the shell layer copolymer on decreasing the minimum film-forming temperature and influencing the end-use properties of coatings.
