摘要：
Polymeric beads and methods of making the polymeric beads are described. The polymeric beads are crosslinked hydrogels or dried hydrogels. The polymeric beads are formed from droplets of a precursor composition that are exposed to radiation. The droplets are totally surrounded by a gas phase. The precursor composition contains a polar solvent and a polymerizable material miscible in the polar solvent. The polymerizable material has an average number of ethylenically unsaturated groups per monomer molecule equal to at least 1.2.
