This investigation combines the processes of capillary breakup of liquid streams into micrometer size droplets and gelation of the liquid contained inside the droplet by thermal crosslinking or thermo-reversible phase separation to obtain gel particles of size ranging from a few hundred nanometers to few hundred micrometers.  This paper presents two case studies.  The first case study considers thermo-reversible gelation of syndiotactic polystyrene (sPS) and the second case study considers gelation by ring-opening polymerization of benzoxazine to obtain polybenzoxazine (PBZ). The macro- and meso-porous particles are characterized in terms of surface area, skeletal density, and shape and size.  Their effectiveness in removal of suspended oil droplets in aqueous media is determined.
