Core–shell polymer supports with different morphological features and compositions
are prepared through combined suspension and emulsion polymerizations.
It is shown that proper manipulation of the divinylbenzene (DVB) feed
content allows for maximization of specific areas, porosities, and mechanical
resistances. Additionally, it is shown that feeding of previously prepared
miniemulsions leads to core–shell particles with smaller specific areas, due to
less efficient coating of the cores. Particularly, the combined manipulation of
polymerization times and DVB feed compositions allows for production of particles
with pronounced specific area (50 m2 g−1) and porosity (0.30 cm3 g−1).
