ABSTRACT:
A substantially water-free, non-dusting and flowable composition comprising an organic peroxide, a hydrocarbyl phthalate, and at least one phlegmatization agent is provided wherein the phlegmatization agent is selected from the group consisting of a polyester and a glycol-based aliphatic carboxylic acid ester, and mixtures thereof. The composition is prepared by: (1) substantially dissolving the hydrocarbyl phthalate and phlegmatization agent in a solvent to form a plasticizer mixture; (2) substantially dissolving the organic peroxide in the plasticizer mixture to form an organic peroxide-plasticizer mixture; (3) cooling the organic peroxide-plasticizer mixture whereby a crystallized composition is formed; and (4) recovering the crystallized composition.
