<p>The present invention provides supported peroxides, and a method of forming supported peroxides. Supported peroxides according to the invention are solid particles that include an organic peroxide, a metallic soap and, optionally, a polymer. In accordance with the method of the invention, supported peroxides are preferably formed by dispersing a mixture that includes at least one peroxide and at least one C4 to C30 carboxylic acid into an aqueous solution that includes a compound that is capable of reacting with the C4 to C30 carboxylic acid to form a water soluble soap. Dispersing the mixture into the aqueous solution results in the formation of an emulsion. Optionally, a polymeric powder is then added to the emulsion to form a suspension. A polyvalent metal compound that is capable of reacting with the water soluble soap to form a water insoluble metallic soap is then added to the emulsion or polymer suspension, which converts the water soluble soap into a water insoluble metallic soap that precipitates from the emulsion or suspension. The organic peroxide and the polymer, if present, are entrained within the precipitate.</p> |
