Abstract
A process for producing organic peroxide initiators useful in the polymerization of ethylenically unsaturated monomers. The process for making the organic peroxides includes forming an aqueous emulsion of the organic peroxide. The organic peroxide is dispersed as small droplets of from 1 to 10 microns in size in the aqueous emulsion. The organic peroxide may be added to a polymerization reactor containing an ethylenically unsaturated monomer. The organic peroxide functions as a free radical initiator to polymerize the monomer. The organic peroxide may be substantially free of organic solvents and plasticizers. The resulting polymers are of high quality.
