Definitions
- TITLE Process for preparing a composition comprising at least the mixture of at least one peroxydicarbonate and at least one peroxyester
- the present invention relates to a process for preparing an organic peroxide composition
- an organic peroxide composition comprising 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 monomers comprising ethylenic unsaturations, preferably one or more halogenated vinyl monomers, and more preferably vinyl chloride.
- the invention also relates to a process for the polymerization of one or more ethylenically unsaturated monomers comprising successively the preparation of the composition, as defined above, and the contacting of said composition with one or more unsaturated monomers. ethylenic.
- the present invention also relates to a halogenated vinyl polymer obtained by polymerization of at least one halogenated ethylenically unsaturated monomer in the presence of the composition as defined above.
- Organic peroxides in liquid or solid form, are commonly used as polymerization initiators of ethylenically unsaturated monomers for the synthesis of different types of polymers, for example halogenated vinyl polymers, such as polyvinyl chloride.
- organic peroxides most often constitute highly unstable species because they decompose relatively easily under the action of a low input of heat, mechanical energy (friction or shock) and / or incompatible contaminants.
- certain organic peroxides can undergo a self-accelerated exothermic decomposition which can lead to fires and / or violent explosions.
- some of these organic peroxides can release combustible vapors capable of reacting with any source of ignition which can drastically increase, or even accelerate, the risks of violent explosion.
- organic peroxides are sometimes stored at storage temperatures well below 0 ° C. before being used as polymerization initiators.
- the organic peroxides are in particular packaged in the form of aqueous emulsions which may comprise antifreeze.
- aqueous emulsions which may comprise antifreeze.
- the presence of water makes it possible to both absorb and dissipate the energy generated in the event of exothermic decompositions of organic peroxides while the role of the antifreeze is to maintain the emulsion in liquid form, at temperatures below -10 ° C, generally below -15 ° C, which makes it possible to limit the risks of an involuntary exothermic decomposition of organic peroxides.
- Aqueous emulsions generally also contain at least one emulsifier having the advantage of lowering the interfacial tension between the aqueous phase and the organic peroxide in order to facilitate the dispersion of the peroxide in the form of droplets and to maintain the size of the latter. in time.
- the peroxide droplets can agglomerate with one another inducing an increase in their average size and in their maximum size which can lead, in certain cases, to a total or partial phase separation and, consequently, to an overall destabilization of the emulsion.
- mixtures of organic peroxides can also be used as polymerization initiators.
- the organic peroxides can be injected separately into the reaction medium containing the ethylenically unsaturated monomers during the polymerization or can be prepared upstream in a separate reactor in order to be added at the start of the polymerization.
- an upstream mixture of organic peroxides also called a premix, is implemented in a suitable reactor before being added to the polymerization reactor.
- Such peroxide premixes are generally packaged in aqueous emulsions.
- premixes most often takes place at a temperature above the storage temperature of the organic peroxides, that is to say at a temperature at which the organic peroxides risk decomposing.
- such premixes can also remain several hours, or even several days, before their use in the reactor in which they have been prepared at a temperature above the storage temperature of the organic peroxides, which increases the risks of thermal decomposition. organic peroxides.
- One of the objectives of the present invention is therefore to prepare mixtures of organic peroxides which do not have the drawbacks described above, which are in particular thermally stable and stable over time.

- the process according to the invention makes it possible to prepare, upstream of their introduction into a polymerization reactor, mixtures of organic peroxides which can be stored and transported, at a temperature above that of the storage temperature of the organic peroxides, so stable to the production site of the final polymer so that they can be used as they are as polymerization initiators.
- the process according to the invention makes it possible to prepare a stable composition of organic peroxides in a suitable reactor located at the place of production of the final polymer, at a temperature above that of the storage temperature of the organic peroxides, and to leaving it to rest in such a reactor in complete safety for a longer or shorter period of time before being used effectively as polymerization initiators.
- the process makes it possible to minimize the formation of free radicals in the premix of organic peroxides, which makes it possible to ensure the quality of the polymer obtained as well as a better yield.
- composition obtained by the process according to the invention can therefore be transported in complete safety within the polymer production plant, in particular from one point to another of the plant, and lead to polymeric materials of good quality. quality.
- the addition of the peroxyester effectively stabilizes the peroxydicarbonate.
- the process according to the invention results in a composition capable of inducing a more homogeneous distribution of the organic peroxides in the polymerization reactor, which improves the reaction time and promotes the production of a better quality polymer.
- Such homogeneity has in particular been observed with respect to the addition of the peroxyester in a polymerization reactor comprising peroxydicarbonate.
- the method according to the invention can advantageously be implemented in the polymer production plant, which saves time from an industrial point of view.
- composition of organic peroxides obtained with the process according to the invention, can advantageously be maintained at a temperature higher than the storage temperature for several hours, or even several days, which offers greater flexibility to the operator for the preparation. production of polymers.
- the process according to the invention also has the industrial advantage of being able to prepare a stable composition which makes it possible to initiate the polymerization of the ethylenically unsaturated monomers at similar rates under reproducible conditions from one polymerization reactor to another and to d '' obtain polymers having a similar quality and / or homogeneous mechanical and chemical properties.
- composition obtained by the process according to the invention can be used repeatedly for several hours, or even several days, after its preparation, while maintaining good stability.
- a subject of the invention is also a process for the polymerization of one or more monomers containing ethylenic unsaturations comprising successively: (i) the preparation of a composition as defined above,

- Figure 2 shows that the content by weight of di (2-ethylhexyl) peroxydicarbonate decreases less rapidly in the presence of 3-hydroxy-1,1-dimethylbutyl peroxyneodecanoate for a period of 96 hours at a temperature of 15 ° C than when the Di (2-ethylhexyl) peroxydicarbonate is alone in the composition.
- the results therefore show that di (2-ethylhexyl) peroxydicarbonate is more stable in the presence of 3-hydroxy-1,1-dimethylbutyl peroxyneodecanoate than alone in the same composition.
- the weight content of di (2-ethylhexyl) peroxydicarbonate was measured at a temperature of 15 ° C for a period of 96 hours: in composition I in the presence of 2% by weight of peroxyester (3 - hydroxy-1,1-dimethylbutyl peroxyneodecanoate - Luperox® 610), in a composition identical to composition I but free of peroxyester, in a composition identical to composition I but comprising 2.5% by weight of tert-butyl peroxyneodecanoate ( Luperox® 10).
- Figure 3 represents as a function of time: the content by weight of di (2-ethylhexyl) peroxydicarbonate alone, curve referenced Lx 223, the content by weight of peroxydicarbonate in the presence of 2% by weight of 3-hydroxy-l, l-dimethylbutyl peroxyneodecanoate, curve referenced Lx 223, 610 (2%), the peroxydicarbonate content by weight in the presence of 2.5% by weight of tert-butyl peroxyneodecanoate, curve referenced Lx 223, Lupl0 (2.5%),
- Figure 3 shows that the content by weight of di (2-ethylhexyl) peroxydicarbonate decreases less rapidly in the presence of a peroxyester over a period of 96 hours at a temperature of 15 ° C than when di (2-ethylhexyl peroxydicarbonate ) is alone in the composition.
- the results therefore show that di (2-ethylhexyl) peroxydicarbonate is more stable in the presence of a peroxyester than alone in the same composition and under the same conditions.
- di (2-ethylhexyl) peroxydicarbonate is more stable in the presence of the hydroxyperoxyester, namely 3-hydroxy-1,1-dimethylbutyl peroxyneodecanoate.
