ABSTRACT:
A process and apparatus are disclosed for producing polymerized beads containing actives such as perfumes and pesticides, by forming droplets from a solution of monomers and the actives. The solution is subjected to ultraviolet light to initiate polymerization. The droplets are caused to fall through a reaction vessel as polymerization continues so as to polymerize substantially spherical beads containing the actives. In one embodiment, the droplets are irradiated as they fall through the reaction vessel. In a second embodiment, the solution is irradiated prior to droplet formation and the fall. The beads are collected and can be cured if necessary. The process is preferably performed in an inert gas environment which most preferably is nitrogen. A nitrogen stream can serve as a carrier for the monomers and active ingredients. The nitrogen environment is maintained in the reaction vessel, and in the curing structure, if present.
