    摘要: Process for preparing an organic solution of a dialkyl peroxydicarbonate in a liquid organic solvent (S), carried out at least partly in the presence of the liquid organic solvent (S) and comprising at least one step during which, in a medium containing water, an alkyl haloformate is reacted with an inorganic peroxide, the solvent (S) being chosen from the compounds corresponding to the empirical formula: A − (C
    n H
    (2n -2) ) − B (I) in which: - A represents a halogen functional group (Al) or a functional group (A2) corresponding to the structure R-C(=O)-O- in which R is chosen from hydrogen; chlorine; substituted or unsubstituted, linear or branched C
    1 -C
    20 alkyl radicals; substituted or unsubstituted C
    3 -C
    22 alkenyl radicals; substituted or unsubstituted C
    6 -C
    10 cycloalkyl radicals; substituted or unsubstituted C
    7 -C
    12 aralkyl radicals, and substituted or unsubstituted C
    6 -C
    10 aryl radicals; - B represents either a hydrogen atom or, when A is not (A2), a second halogen functional group (A1); and - n is such that 3 ≤ n ≤ 8. Organic solution of a dialkyl peroxydicarbonate in this solvent (S) and process for preparing a polymer derived from one or more halogenated ethylenically unsaturated monomers.

    摘要: The current invention relates to the stabilisation of peroxyacid solutions. There is provided a tin based stabiliser composition obtained by the ageing of an alkaline solution of a tin compound and a phosphorus containing compound. The stabiliser is particularly suitable for the stabilisation of non-equilibrium solution of peroxyacids.
