The reaction between the ketone peroxide of the formula II and the alkyl vinyl ether of the formula IIIa or the acetal of the formula IIIb is carried out under conventional conditions for this type of addition reactions. The temperature is generally in the range of 0-50 ° C and preferably between
-25 ° C. The reaction is carried out in the presence of an acid catalyst.
The amount of acid catalyst is generally 0.01 -30 g / mol and preferably 0.1-15 g / mol of ketone peroxide. The acid catalyst for the process is a conventional acid catalyst such as the C 1 -C alkane or an arylsulfonic acid, a halogenated C 1 -C 10 alkanesulfonic acid or a mixture of one or more of these compounds. Preferred catalysts for use are, but are not limited to, p-toluenesulfonic acid and methanesulfonic acid. Although this reaction can be carried out without a solvent, it is preferred to carry out the reaction in a conventional homogeneous solvent system. Suitable solvents are generally hydrocarbon solvents, esters, aromatic hydrocarbon solvents, aralkyl solvents, paraffinic oils, white oils, and silicone oils, as well as mixtures thereof. The use of solvents includes, but is not limited to, benzene, xylene, toluene, mesitylene, hexane, hydrogenated alkane oligomers such as Isopar products (eg Exxon), Shellsol® products (eg Shell), pentane, heptane, decane, sododecane, decalin, dibutyl phthalate, dioctyl adipate, dioctyl terephthalate, 2,2,4-tri-methyl-1,3-pentanediol diisobutyrate, butylbenzoate, and the like. Among the paraffinic oils used as solvents is paraffinic diesel oil. Other oils include white oils, epoxidized soybean oils, and silicone oils that are also useful in the present invention. Preferably, R4 is a hydrogen because the peroxide shows better storage stability at room temperature and is less sensitive to hydrolysis. More preferably, R and R5 and / or R6 are hydrogens. Generally, the process for preparing the peroxide is carried out so that an equivalent amount of the alkyl vinyl ether of the formula Illa or the acetal of the formula IIIb is in the range of 1-5 equivalents. Preferably, the range is from 1.5 to 3.0 equivalent, more preferably from 2.0 to 2.5 equivalents. These equivalent numbers are selected so that the chemical yield is optimal. It was noted that in the preparation process the ketone peroxide used can be a pure ketone peroxide (T4) of the formula lal or a ketone peroxide (T3) of the formula! Lb. For specific properties it may be advisable to use a mixture of ketone peroxide T4 and T3. For example, ketone peroxide T3 or T4 may comprise 5% -30% ie 5% -25% and 10% -15%, of the other ketone peroxide. In addition, the invention relates to the peroxides of the formula I
where R1? R2, R3, R4, R5 and R6 have an identified meaning and which are obtained with the preparation process described above. The peroxides according to the present invention produced with the preparation process according to the present invention can be used as initiators of the production of polymers and in particular for the preparation of (poly) vinyl chloride, acrylic (co) polymers, polystyrene, polyethylene, for curing unsaturated polyester resins, and for polymeric modification (such as the grafting of monomers). In the present invention, the polymerization was conducted by any conventional method, with the exception that a specified radical polymerization initiator (or composition) was used. The polymerization process can be carried out in the usual manner, for example in a mass, suspension, emulsion or solution. In the case of the production of ethylene (co) polymers, the reaction is usually carried out under high pressure, ie of about 1000 to 3500 bars. The amount of initiator, which varies depending on the polymerization temperature, the ability to remove heat from the polymerization, and, where applicable, the type of monomer to be used, and the applied pressure, must be an effective amount to achieve polymerization. Usually, 0.001-25% by weight of peroxide is employed, based on the weight of the (co) polymer. Preferably 0.001-20% by weight peroxide is used and more preferably 0.001-15% by weight. For most reactions within the present invention, the polymerization temperature is usually 30 ° to 350 ° C, preferably 40 ° to 300 ° C. In general, if the temperature is below 30 ° C, the polymerization time becomes too long. However, when this exceeds 350 ° C, the radical polymerization initiator is spent in the initial stage of the polymerization, making it difficult to achieve high conversion. In order to reduce the amount of non-reactive monomer, therefore, it is possible to conduct the polymerization using a temperature profile, that is, perform the initial polymerization below 100 ° C and then raise the temperature above 100 ° C. C to complete the polymerization. These variations are completely known by the experts, who will have no difficulty in selecting the conditions of choice of the reaction, depending on the particular polymerization process and the specific radical polymerization initiator to be used. The monomers suitable for polymerization using the peroxides according to the present invention are ethylenically unsaturated or olefinic monomers, for example substituted or unsubstituted vinyl aromatic monomers including styrene, alpha-methylstyrene, p-methylstyrene, and halogenated styrenes; divinylbenzene; ethylene; ethylenically unsaturated carboxylic acids and derivatives thereof, such as (meth) acrylic acids, (meth) acrylic esters, butylacrylate, hydroxyethyl (meth) acrylate, methyl (meth) acrylate, 2-ethylhexyl (meth) acrylate, and glycyl methacrylates; ethylenically unsaturated nitriles and amides, such as acrylonitrile, methacrylonitrile, and acrylamide; unsubstituted or substituted ethylenically unsaturated monomers, such as butadiene, isoprene, and chloroprene; vinyl esters such as vinyl acetate and vinyl propionate; ethylenically unsaturated dicarboxylic acids and their derivatives including mono- and diesters, anhydrides, and imides, such as maleic anhydride, citraconic anhydride, citraconic acid, itaconic acid, nadic anhydride, maleic acid, fumaric acid, aryl, alkyl, and aralkyl cyraconimides and maleimides; vinyl halides, such as vinyl chloride and vinylidene chloride; vinyl ethers, such as methylvinyl ether and N-butylvinyl ether; olefins, such as isobutene and 4-methylpentene; allyl compounds, such as (di) allyl esters, for example diallyl phthalates, (di) allyl carbonates, and detriallyl (iso) cyanurate.

As an example of such additives, there may be mentioned: stabilizers such as oxidative, thermal or ultraviolet degradation inhibitors, lubricants, dilation oils, pH controlling substances, such as calcium carbonate, release agents, dyes, fillers reinforcing or not reinforcers such as silica, clay, gypsum, carbon black, and fibrous materials, such as fiberglass, plasticizers, diluents, chain transfer agents, accelerators, and other types of peroxides. These additives can be used in the usual amounts. Finally, the polymerization process of the present invention can be used to introduce functional groups into (co) polymers. This can be done by using peroxide that contains one or more functional groups attached to it. These functional groups remain intact in the free radicals formed by the peroxides and are thus introduced into the (co) polymer. Conditions and equipment for conventional polymerization can be used to achieve the objective of the present invention. The peroxides according to the invention which can be used as binding agents for the unsaturated polyesters and unsaturated polyester resins according to the present invention usually include an unsaturated polyester and one or more ethylenically unsaturated monomers. Suitable polymerizable monomers include styrene, alpha-methylstyrene, p-methylstyrene, chlorostyrenes, bromostyrenes, vinylbenzyl chloride, divinylbenzene, diallyl maleate, dibutyl fumarate, triallyl phosphate, triallyl cyanurate, diallyl phthalate, dialkyl fumarate, methyl (meth) acrylate, -butyl (meth) acrylate, ethyl acrylate, and mixtures thereof which are copolymerizable with unsaturated polyesters. The unsaturated polyesters are, for example, polyesters since they are obtained by the styration of at least one ethylenically unsaturated di-copolycarboxylic acid, anhydride or acid halide, such as maleic acid, fumaric acid, glutaconic acid, itaconic acid, mesaconic acid , citraconic acid, allylmalonic acid, tetrahydrophthalic acid, and others, with saturated and unsaturated diols or polyols, such as ethylene glycol, diethylene glycol, triethylene glycol, 1,2- and 1,3-propanediols, 1, 2, 1, 3 -, and 1,4-butanediols, 2,2-dimethyl-1,3-propanediols, 2-hydroxymethyl-2-methyl-1,3-propanediol, 2-buten-1,4-diol, -butin-1,4-diol, 2,4,4-trimethyl-1,3-pentanediol, glycerol, pentaerythritol, mannitol and others.

The acids used can be substituted with groups such as halogen. Suitable halogenated acids include, for example, tetrachlorophthalic acid and tetrabromophthalic acid. The peroxides of the present invention are suitable for use in the modification of polymers such as degradation, crosslinking or grafting. More particularly, these peroxides can be used in processes for grafting monomers into polymers such as polyolefins, and elastomers, and for functionalizing polyolefins in the case of peroxides containing functional groups of the present invention. In general, the peroxide can be contacted with the (co) polymer in various ways, depending on the particular object of the modification process. The polymeric material can be in a solid state, in the molten state, in the form of a solution in the case of an elastomer, in a plastic state or in any physical form including finely divided particles (flakes), pills, film, foil, in the molten material, in solution, and the like. The polymers can also be in liquid form, ie liquid gums.
In general, any (co) polymer comprising extractable hydrogen atoms, in particular polyolefins, can be modified by the present process. The amount of peroxide used in the modification process of the present invention should be an amount effective to achieve a significant modification of the (co) polymer when treated with a (co) polymer, more particularly 0.001-150.0% by weight of peroxide based on the weight of the (co) polymer, it should be used. More preferably, 0.005-10.0% by weight percent is employed. More preferably still, an amount of 0.01-5.0% by weight is employed. Peroxides can be prepared, transported, stored, and applied in the form of powders, granules, pellets, concentrates, flakes, slabs, paste, and solid and liquid master batches. These formulations can take the form of a dispersion, such as a suspension or an emulsion. These can be phlegmatized if necessary, depending on the particular peroxide and its concentration in the formulation. Which of these forms is preferred depends in part on the application for which it will be used and partly on the manner in which it will be mixed. Also, safety considerations may play a role in the degree of phlegmatization that can be incorporated into certain compositions to ensure safe handling. The formulations of the present invention are transportable, storage stable, and contain 1.0-90% by weight of one or more peroxides according to the present invention. Transportable means that the formulation of the present invention has passed the pressure vessel test (PVT). Stable storage means that the formulations of the present invention are both chemically and physically stable for a reasonable storage period under standard conditions. Preferred formulations according to the present invention contain 10-90% by weight of one or more of the peroxides, more preferably these formulations contain 30-90% by weight of the peroxides, and even more preferably these formulations contain 40-80% in weight of the peroxides. The formulations of the present invention can be liquid, solid or pastes, depending on the melting point of the peroxide and the diluent employed. Liquid formulations can be made using liquid phlegmatizers for ketone peroxide, liquid plasticizers, organic peroxides, and mixtures thereof as diluents. The liquid component is generally present in an amount of 1-88% by weight of the composition, preferably 10-90% by weight, more preferably 30-90% by weight, and more preferably 40-80% by weight of the liquid formulation which consists of liquid diluents. It should be noted that certain phlegmatizers may not be suitable for use with all peroxides of the present invention, more particularly, in order to obtain a safe composition, the phlegmatizer must have a certain minimum flash point and a boiling point relative to the decomposition temperature of the peroxide in such a way that the phlegmatizer can not boil leaving behind a concentrated and insecure ketone peroxide composition. Thus, the low boiling of the phlegmatizers mentioned below may only be useful, for example, with particular substituted peroxides of the present invention having a low decomposition temperature. In liquid formulations a liquid carrier or diluent is used. Preferably, this vehicle or diluent is a solvent. Examples of the solvents are those given above for the preparation of various peroxides. Solid carrier materials are used in the solid and / or paste formulations of the present invention. Examples of such solid carriers are solids with low melting point, such as dicloexil phthalate, dimethyl fumarate, dimethyl isophthalate, triphenyl phosphate, glyceryl tribenzoate, trimethyl oletantribenzoate, dicycloxy terephthalate, paraffin waxes, dicyclohexyl isophthalate, polymers and inorganic supports. Inorganic supports include materials such as evaporated silica, precipitated silica, hydrophobic silica, chalk, white from Spain, treated clays for surfaces such as silane treated clay, calcined clay and talc.

The formulations stable to storage must be stable both physically and chemically. By physically stable formulations are meant those formulations that do not suffer from a significant phase separation once they are stored. The physical stability of the present formulations can, in some cases, be improved by the addition of one or more thixotropic agents selected from cellulose esters, hydrogenated castor oil; and evaporated silica. Examples of said cellulose esters are the reaction products of cellulose and acidic compounds selected from, for example, acetic acid, propionic acid, butyric acid, phthalic acid, trirnethyl acid, and mixtures thereof. By chemically stable formulations are meant those formulations that do not lose a significant amount of their active oxygen content once they are stored. The chemical stability of the present formulations can, in some cases, be improved by the addition of one or more known additives including sequestering agents such as dipicolinic acid and / or antioxidants such as phenol 2,6-di (t-butyl) -4-methyl and para-nonyl phenol.
The formulations of the present invention may also contain other optional additives as long as they do not have a significant adverse effect on the transportability and / or storage stability of the formulations. As examples of said additives, mention may be made of: anti-coagulation agents, free-flowing agents, antiozonants, antioxidants, anti-degradants, UV stabilizers, coagents, fungicides, antistatics, pigments, dyes, coupling agents, dispersing aids, dispersing agents, lubricants, processed oils. , mold release agents. These additives can be used in their usual amounts. The peroxides according to the invention can also be used as a dispersion, preferably in the polar medium. The medium in which the initiator according to the invention is dispersed should be inert towards the initiator and so polar that the initiator will hardly dissolve in it. The initiator is preferably dispersed in water or in alcohol. More preferably in a dispersion in water. Said medium is easily removed in comparison with any remnant, for example after modification of the (co) polymer if desired. Therefore, the use of water or alcohols is expected to be less profitable and have other drawbacks than the use of organic diluents such as toluene and xylene, which have been common up to now. As any expert knows, the use of other adjuvants in the dispersion of the initiators may be advisable or even essential in order to ensure that the chemical dispersion and / or the physical stability continue for a long period. For example, if the storage temperature of the dispersion initiator is less than the freezing point of the medium in which the initiator is dispersed, an appropriate freezing point depression agent may be added to counteract the freezing. Also, a wide range of substances can be used to alter the rheology of the formulation. At this point one or more surface active materials and one or more thickeners are generally used. If desired, other additives can be incorporated into the formulation. As examples of such additives there may be mentioned pH buffers, chemical stabilizers which counteract the premature decomposition of the initiator, and anti-aging compositions which counteract the growth of the size of the particles in the dispersion. The following examples illustrate the process for preparing the peroxides according to the present invention and their applications.
