Definitions
- the subject of the invention is an aqueous peroxyester emulsion, which can be used for the polymerization or copolymerization of ethylenically unsaturated monomers and in particular of vinyl chloride.
- the most reactive organic peroxides are commonly packaged as an aqueous emulsion in the presence of antifreeze.
- This conditioning makes it possible both to absorb and dissipate the energy generated in the event of any decompositions of the peroxides and to maintain the emulsion in liquid form, at temperatures below -10 ° C, generally below -20 ° vs. This conditioning thus limits a possible involuntary decomposition of the peroxides.
- Organic peroxide emulsions generally include, in addition to water and antifreeze, an emulsifier which lowers the interfacial tension between the aqueous phase and the organic peroxide to facilitate its dispersion in the form of droplets and stabilize the latter. over time (maintaining the size of the droplets).
- the stability of organic peroxide emulsions is essential in terms of safety (during production, transport and storage) but also for use during polymerization.
- inhomogeneous organic peroxide emulsion as a polymerization initiator in an emulsion or suspension of vinyl monomer can produce inhomogeneity in the final product.
- This inhomogeneity is generally characterized by poorly gelled polymer particles during processing in the molten state (“fish eyes”, hard grains).
- fish eyes hard grains
- hard grains opacifies the polymer material.
- the emulsion becomes destabilized and the average size of the peroxide droplets increases. Increasing the size of the droplets can cause phase separation.
- a peroxide emulsion is generally considered satisfactory if the average droplet size does not exceed 5 ⁇ m, the maximum droplet size does not exceed 20 ⁇ m, and the droplet size distribution is homogeneous.
- the steps of unloading the emulsions of organic peroxides into intermediate storage silos, pumping and introduction into a polymerization reactor are important steps for the quality of the polymer obtained and the reliability of the polymerization process. These steps should be completed as quickly as possible. To do this, it is crucial that the organic peroxide emulsions have a low viscosity so that the emulsion flow is maximally facilitated.
- an organic peroxide emulsion must have a maximum dynamic viscosity of 1000 mPa.s (milliPascal second) at -10 ° C for a shear rate of 100 s 1 (The dynamic viscosity measurements are carried out using cylinders coaxials that create shear, for example according to DIN 53019).

- This document also states that the addition of surfactants, with an HLB less than 10, has a detrimental effect and increases the final viscosity of the organic peroxide emulsion.
