Abstract (en)
[origin: WO2021234313A1] The present invention relates to a method for preparing an organic peroxide composition containing the mixture of at least one peroxydicarbonate and at least one peroxyester, preferably at least one hydroxyperoxyester; said composition being prepared before being brought into contact with one or more ethylenically unsaturated monomers, preferably one or more halogenated vinyl monomers, and more preferably vinyl chloride. The invention also relates to a method for polymerizing one or more ethylenically unsaturated monomers, the method comprising, successively, preparing the composition, as defined above, and bringing said composition into contact with one or more ethylenically unsaturated monomers.
