  • Patent number: 7053161
    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.

  • Patent number: 6878840
    Abstract: The dialkyl peroxydicarbonates with short alkyl chains, preferably diethyl and diisopropyl peroxydicarbonates, are used for the aqueous suspension polymerization of vinyl chloride, in the form of a solution in a dialkyl alkanedicarboxylate which is liquid and insoluble in water. The preferred solvents are hexanedicarboxylates (adipates) derived from adipic acid and from C6-C10alkanols. The peroxydicarbonate concentration of the said solutions is generally 15-40% by weight. The process according to the invention produces vinyl chloride polymers of improved quality resulting in shaped articles exhibiting markedly fewer fisheyes. The invention also relates to a two-stage process for the manufacture of a solution of dialkyl peroxydicarbonates with short alkyl chains which is particularly suited for the aqueous suspension polymerization of vinyl chloride.
