- 1Hele blandingen blir tilsatt en polymeriseringsreaktor som inneholder en etylenisk umettet monomer. Peroksidikarbonatet fungerer som en fri radikal initiator som polymeriserer monomeren. Peroksidikarbonatet er hovedsakelig fri for organiske ;oppløsningsmidler og plastifiseringsmidler. De resulterende polymerene har høy ' kvalitet. The entire mixture is added to a polymerization reactor containing an ethylenically unsaturated monomer. The peroxydicarbonate acts as a free radical initiator which polymerizes the monomer. The peroxydicarbonate is substantially free of organic;solvents and plasticizers. The resulting polymers have high quality.

Oxy Vinyls LP, 5005 LBJ Freeway, Dallas, TX 75244, US Ross James Cozens, Strongsville, OH 44136, US Protector Intellectual Property Consultants AS, 0301 Oslo (54) Description Method for the preparation of peroxydicarbonates and their use in radical polymerization of monomers ( 57) Summary
A process for preparing peroxydicarbonates comprises first reacting an inorganic peroxide with at least one alkali metal hydroxide to form at least one alkali metal peroxide. The at least one alkali metal peroxide is added to a mixture with at least one halophimate, at least one dispersant and water. The mixture is homogenized throughout the reaction to form a peroxydicarbonate. The peroxydicarbonate is dispersed as droplets of size from 1 to 10 microns in the aqueous mixture.
