Aqueous emulsion comprising: &#x2014;25-70 wt % organic peroxide, based on the weight of the emulsion, &#x2014;a cyclohexane dicarboxylate ester, and &#x2014;water. This emulsion is storage stable and can be used for the production of polymers, in particular PVC, that come into contact with food products.

Storage stable aqueous organic peroxide emulsions

A process for the polymerization of one or more monomers wherein at least one anhydride and at least one peroxy compound selected from inorganic peroxides, organic hydroperoxides, and peroxyacids are dosed during the polymerization reaction in a continuous or intermittent fashion to a reaction mixture comprising said monomers.

Polymerization process with in-situ initiator formation

The invention relates to a process for preparing saturated or unsaturated lactones. This process involves reacting a bicyclic compound or a monocyclic compound with hydrogen peroxide in the presence of a first acid having a pKof 3 or less and a first organic solvent, thereby forming a hydroperoxide. The obtained mixture comprising the hydroperoxide is subsequently metered to a mixture of a second organic solvent and a dissociation-enhancing catalyst, optionally comprising a second organic acid. The invention also pertains to a process of preparing the hydroperoxide.

Process for preparing unsaturated lactones

The invention pertains to an aqueous composition having a pH of 3 or less and comprising the following ingredients, based on the total weight of the composition: a) 0.05-40 wt % of a polymeric thickener having &#x2014;COOR groups, wherein R is independently chosen from H, OH, and a carbon-containing group, and b) 0.05-60 wt % of hydrogen peroxide, wherein the active oxygen content attributable to ingredient a) is at least 0.02 wt %, based on the total weight of the composition, with the proviso that (co)polymers prepared from (meth)acrylate monomers are absent.
