ABSTRACT OF THE DISCLOSURE A Safe, Dry and Free-Flowing Solid Peroxide/ Aromatic Carboxylic Acid Composition is prepared by mixing the solid peroxide, such as diacyl peroxide, dialkyl peroxydicarbonate, dialkyl peroxide or alkylidene diperoxide, which melts above 30°C, with a solid aromatic carboxylic acid, particularly unsubstituted or alkyl-substituted benzoic acid, which melts above 40°C. This solid peroxide composition is used as an initia- tor for the polymerization of ethylenically unsaturated monomers, such as sytrene, and for curing of unsaturated polyester resins and diethylene glycol bis(allyl carbonate). This solid peroxide composition exhibits improved safety characteristics such as delayed ignition times when in contact with a flame and increased thermal stabilities compared to similar prior art peroxide formulations.
