Abstract:
1. Process comprising the steps of: producing an aqueous mixture comprising a diacyl peroxide of formula (I)  wherein R  wherein X is halide, preferably chloride or bromide, most preferably chloride, with i) MOOH/M  or the M salts thereof, in an aqueous phase, in which process the acid halide, or mixture of acid halides, is essentially only brought into contact with water containing MOOH/M optionally introducing one or more solvents for the acid halide in any part of the process, optionally introducing one or more salts in any part of the process, optionally introducing one or more colloids and/or surfactants, before, during, or after the peroxidation step, optionally purifying the aqueous mixture in one or more purification steps, optionally homogenizing the aqueous mixture in one or more homogenization steps, transferring the product from the previous steps that comprises the diacyl peroxide of formula (I) to a polymerization reactor, and thermally decomposing said diacyl peroxide, to generate organic free radicals, in the presence of one or more ethylenically unsaturated monomers, to polymerize said monomers in said polymerization reactor.
