Synthesis of Polymer Nano Particle using Packed Reactor with Glass Beads

Soap-free emulsion polymerization was carried out to synthesize polymer nano particles using the packed reactor with glass beads whose sizes were ranging from 15 to 90 μm. The hydrogen bonding between water and glass bead reduced the fluidity of water solvent. As a result, the motions of the particles through the polymerization were suppressed to decrease their collision frequencies for growth. The particle size was under 100 nm and controllable with the glass beads size. The packed reactors was change to be ice reactor by freezing, which enabled the polymer nano particles to be synthesized.
