Notes:
Monosized droplets of 2-hydroxyethyl methacrylate (HEMA) and glycerol monomethacrylate (GMA) were made by passing the monomers under pressure through a nozzle coupled to an energized piezoelectric crystal. The droplets were allowed to fall into liquid nitrogen where they vitrified. The radiation post-polymerization of the monomer spheres was investigated. Uniform monosized poly-HEMA particles in the 100-300 μm diameter range were prepared with a coefficient of variation of 1.57% for particles of 155 μm in diameter. Monosized poly-GMA was also prepared. The post-polymerization conversion of pre-irradiated GMA vitrified monomer droplets as a function of thawing rate and radiation dosage was investigated.
