Ion-exchange resins based on 2-vinylpyridine and divinylbezene (DVB) were synthesized, in the presence of n-heptane and diethylphthalate as diluents, by suspension polymerization. The effects of type and content of these diluents and the DVB content on the development of porosity of the resins were
Styrene-divinylbenzene copolymers were synthesized in the presence of di(2-ethylhexyl)phosphonic acid (EHEHPA) to be applied in the separation of rare earths by extraction chromatography. The copolymers were prepared by suspension polymerization in the presence of pure EHEHPA or in a mixture with is
