Main regularities for precipitation of inorganic modifiers inside ion
exchange (weakly and strongly acidic as well as strongly basic; flexible and
rigid) and inert polymers are considered. The Ostwald-Friendlich equation was
applied to obtain the relations, which allows us to determine the conditions for
purposeful formation of one or other particles (non-aggregated nanoparticles,
aggregates and agglomerates). The obtained composites were investigated with
methods of transmission and scanning electron microscopy, standard contact
porosimetry, 31P NMR spectroscopy. In the case of embedded phosphate
compounds, the spectra show 2 signals that are attributed to hydro- and
dihydrophosphate groups (aggregated particles) or several signals (single
nanoparticles).
