  • Method for manufacture of aqueous suspension of solid organic peroxide
    Patent number: 4734135
    Abstract: An aqueous suspension of a solid organic peroxide is produced by mixing a solid organic peroxide having a difference of at least 5.degree. C. between the melting point and the thermal decomposition temperature thereof with a protective colloid, a surface active agent, and water thereby forming an aqueous emulsion and subsequently cooling this aqueous emulsion.
