Description
PEROXIDES, PROCEDURE FOR PREPARATION AND USE OF THEMSELVES
DESCRIPTIVE MEMORY
The present invention relates to particular peroxides, mixtures comprising one or more of these peroxides, their method of preparation and their use. More particularly, the present invention relates to the process for the preparation of peroxyesters and peroxycarbonates, peroxyester-peroxycarbonates, and mixed peroxides, and mixed peroxy esters and mixed diperoxycarbonates, and specific aminoperoxyesters, monoperoxy carbonates, mixed peroxides, and mixed peroxyesters and mixed diperoxycarbonates peroxy esters - peroxycarbonates, and mixtures thereof. Finally, the present invention relates to these peroxides as polymerization initiators, curing agents for unsaturated polyesters and modifying agents, and to formulations comprising these peroxides. JP-A-50-23079 discloses the production of symmetrical peroxides by reacting a dialkylketone hydroperoxide with an acyl chloride in a two-phase solvent system comprising a polar (aqueous) solvent and an apolar solvent. A monoperoxy ester or a monoperoxycarbonate is not formed. Peroxyesters are used in the homopolymerization of ethylene or the copolymerization of ethylene and another ethylenically unsaturated monomer.
JP-A-48-43491 discloses a similar method for the production of diperoxycarbonates. Since these procedures of preparation of the technique
• above do not result in the monoperoxyester formulation or
In the case of monoperoxycarbonate as the main constituent, it is not possible to produce asymmetric diperoxy esters, diperoxycarbonates and mixed peroxides in a controlled manner. It is an object of the present invention to provide a new class of monoperoxyesters and monoxicarbonates which on the one hand are useful
• 10 as polymerization initiators, curing agents for unsaturated polyesters and modifying agents, and on the other hand serve as starting material for the production of a novel class of mixed peroxides, and mixed peroxiesters, mixed diperoxycarbonates and peroxyester peroxycarbonates which are useful as polymerization initiators, curing agents for unsaturated polyesters and modifying agents. The present invention is based on the insight that by the appropriate selection of acetone peroxides on the one hand and acid halogen or halogenoformlate on the other hand, monoperoxiesters and monoperoxycarbonates are formed in an adjustable relative amount. These monoperoxyesters and monoperoxycarbonates allow the provision of a new class of mixed peroxides, mixed diperoxyesters, mixed diperoxycarbonates and peroxyester-peroxycarbonates.
Accordingly, the present invention provides a process for the preparation of monoperoxy ester or monoperoxycarbonate having the general formula I:
where Ri and R2 are independently selected from the group
• comprising halogen, C? -C20 alkyl, C3-C20 cycloalkyl, C6-C2o aryl, C -C2o aralkyl and C -C2o alkaryl, or Ri and R2 form a C3-C12 cycloalkyl group, groups which may include linear or branched alkyl portions, and each of Ri and R2 may be optionally substituted with one or more groups selected from hydroxy, alkoxy, linear or branched alkyl, aryloxy, halogen, ester, carboxy, nitrile and amido, and R3 is independently selected from the group comprising
• C? -C20 alkyl, C3-C20 cycloalkyl. C6-C2o aryl, C7-C20 aralkyl and C7-C20 alkaryl, which group may include linear or branched alkyl portions, and R3 may be optionally substituted with one or more groups selected from hydroxy, alkoxy, linear or branched alkyl , aryloxy, halogen, ester, carboxy, nitrile and amido, which process comprises the reaction of the corresponding ketone peroxide with the general formula II:
wherein Ri and R2 have the identified meaning, with a reactive carbonyl compound with the general formula III:
Wherein R3 has the identified meaning and L is a group that activates a carbonyl carbonyl compound (III) for its reaction with the ketone peroxide "II", in a two-phase inert solvent system comprising a polar solvent and an apolar solvent. The ketone peroxides of the formula II are also known as ketone peroxides of type 3
(T3). The inert two-phase solvent system comprises a polar solvent and an apolar solvent. Preferably, the polar solvent is a phase comprising an aqueous alkali. The apolar solvent is not miscible with the polar solvent. A solvent is a polar solvent when its dipole moment is greater
than OD and preferably greater than 0.5D, in other words, when they have a certain polarity. A solvent is an apolar solvent when its dipole moment is 0.5D or less, preferably essentially DO. The apolar solvent has substantially no polarity.
Suitable polar solvents comprise cycloalkanol alcohols, ethers, ethylene glycols, amides, aldehydes, ketones, esters, halogenated hydrocarbons such as cloned hydrocarbons, and mixtures of
• the same. The use of polar solvents such as anhydrides, carbonates and epoxides is less desired, since they are not completely inert. However, an aqueous (alkaline) phase is preferred as the polar solvent. Suitable apolar solvents are generally hydrocarbon solvents, aromatic hydrocarbon solvents, aralkyl solvents, paraffinic oils, white oils and silicone oils, as well as
• 10 their mixtures. The hydrocarbon solvents include, but are not limited to, benzene, xylene, toluene, mesitylene, hexane, hydrogenated oligomers of alkanes such as Isopar products (exxon), SheIlsol® products (Shell), pentane, heptane, decane, isododecane, decalin and the like. Paraffinic oils, useful as apolar solvents,
comprise, for example, paraffinic diesel oil. Other oils, including white oils, epoxidized soybean oils and silicone oils, are
• also useful in the present invention. Properly selected the equivalent amount of the carbonyl compound used in the preparation process, it can be
further adjust the amount of monoperoxy ester and monoperoxycarbonate. The amounts are preferably selected such that at least 10% by weight of the desired product is formed. More preferably, such that at least 25% by weight of these products is formed. More preferably still, the amount of halogen acid or halogenoformate is in the range of 0.5-5 equivalents, so that the amount of monoperoxy ester and monoperoxycarbonate formed is at least 50% of the peroxides produced. Using 0.9-2.5 equivalents, the selectivity is further increased. An equivalent amount on the scale of 1-2 equivalents is very preferred. Then, the selectivity is generally above 60%, such as above 80% or even above 90%. This selectivity of the mono: bis ratio can be expressed. The reaction conditions are conventional. The temperature is generally in the range of -10 to 50 ° C and suitably between 0 and 30 ° C. A practical scale is 5 to 15 ° C. Essentially, the temperature is selected in such a way that side reactions and decomposition of the materials are avoided. The pH is alkaline, that is, above 7. Generally, the pH is on the scale of 9-14. In practice, the pH is above 10 and a practical scale is 11 to 13.5. The reaction proceeds under ambient pressure and in free contact with the atmosphere. The acetone peroxides suitable for the reaction for the carbonyl compound are the derivatives of the following ketones: acetone, acetophenone, methyl n-amyl ketone, ethylbutyl ketone, ethylpropyl ketone, methyl isoamyl ketone, methylheptyl ketone, methylhexyl ketone, ethylamyl ketone, diethyl ketone, dipropyl ketone, methyl ethyl ketone.methylbutyl ketone, methylisopripyl ketone, methylpropyl ketone, methyl-n-butyl ketone, methyl t-ketone, isobutylheptyl ketone, diisobutyl ketone, methyl ketone, methoxyacetone, cyclohexanone, 2,4,4-trimethylcyclohexane, N-butylevulinate, ethylacetoacetate, methylbenzylketone, phenylethyl ketone, methylchloromethyl ketone, methyl bromomethyl ketone and coupling products thereof. Other ketones having the appropriate Ri and R2 groups corresponding to the peroxides of formula II can also be used. L can be any group that activates the carbonyl group of the carbonyl compound for reaction with a hydroperoxide group of the ketone peroxide and does not substantially interfere with this reaction. Some suitable examples of L are halogen and the groups -O-R3 ', -O-CO-R3' and -O- # 10 CO-O-R3 '. R31 is selected independently from R3 of the same group of substituents as R3. When L is halogen, the carbonyl compound (III) is an acid halogen or a halogenoformate. When I is the group -O-R3 ', the carbonyl compound (III) is a carboxylic acid ester or a carbonate. When L is the group -O-CO-R3 ', the carbonyl compound (III) is a
carboxylic acid anhydride or a mixed anhydride. When L is the group -O-CO-0-R3, the carbonyl compound (III) is a pyrocarbonate or an anhydride

In the present invention, the polymerization is conducted by any conventional procedure, except that a stanified radical polymerization initiator (or composition) is used. The polymerization processes can be carried out in the usual manner, for example in volume, suspension, emulsion or solution. In the case of the production of ethylene (co) polymers, a reaction is usually carried out under high pressure, for example, from about 1000 to about 3500 bar. The amount of initiator, which varies depending on the polymerization temperature, the ability to remove heat from polymerization and, if applicable, and the amount of monomer to be used and the applied pressure, must be an effective amount to achieve the polymerization.

Preferably, from 0.001 to 20% by weight of peroxide and most preferably from 0.001 to 15% by weight is employed. 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 it exceeds 350 ° C, the radical polymerization initiator is wasted in the initial stage of the polymerization, making it difficult to achieve high conversion. In order to reduce the amount of monomer reacted, however, it is also possible to conduct the polymerization using a temperature profile, for example, to perform the initial polymerization at less than 100 ° C and then raise the temperature to more than 100 ° C.

The polymer material may be in the solid state, molten state, in the form of a solution in the case of an elastomer, and in a plastic state or in any physical form including finely divided particles, "flakes", pellets, films, foil, in casting, in solution, and similar. The polymers can also be in liquid form, for example liquid gums.

The said cellulose esters are the reaction products of celluloses and acid compounds selected from, for example, acetic acid, propionic acid, butyric acid, phthalic acid, trimellitic acid, and mixtures thereof. By stable chemical formulations means those
formulations that do not lose a significant amount of their active oxygen content with storage. The chemical stability of
The present formulations can be improved, in some cases, by the addition of one or more known additives including sequestering agents such as dipicolinic acid and / or antioxidants such as 2,6-di (t-butyl) -4-20 methylphenol and -nonylphenol. The formulations of the present invention may also optionally contain other additives as long as they do not have a significant adverse effect on the transportation capacity and / or stability and storage of the formulations. As examples of said additives there may be mentioned: plast antifouling agents, free-flowing agents, antiozonants, anti-oxidants, antidegradants, UV stabilizers, coagents, fungicides, antistatics, pigments, dyes, coupling agents, dispersion aids, blowing agents, lubricants, processing oils, and mold release agents. These additives can be used in their usual amounts. The ketone peroxides according to the invention can also be used as a dispersion, preferably in a polar medium. The medium in which the initiator according to the invention is dispersed must be inert towards the initiator and so polar that the initiator will hardly dissolve therein. The initiator is preferably dispersed in water or in an alcohol. More preferable is a dispersion in water. The use of said means makes a comparatively easier removal of any remnants, for example after modification of the copolymer if so desired. In addition, the use of water or alcohols is attended with much less organoleptic and other disadvantages than the use of organic diluents, such as toluene and xylene, which have been common up to now. As is well known to the person skilled in the art, the use of other adjuvants in initiator dispersions may be advisable or even essential in order to ensure the chemical and / or physical stability of the dispersion for a sufficiently long period of time. For example, if the storage temperature of the initiator dispersion is lower than the freezing point of the medium in which the initiator is dispersed, a suitable freezing point depression agent can be added to counteract the freezing. In addition, you can use a wide
* scale of substances to alter the rheology of the formulation. For this purpose, generally one or more surface active materials and one or more thickeners are used. If desired in this way, other additives can be incorporated into the formulation. Examples of such additives are pH regulators, biocides, chemical stabilizers that counteract the premature decomposition of the initiator, and anti-fouling agents.
• 10 that counterattack the particle growth in the dispersion. By using mixtures of monoperoxyesters or monoperoxycarbonates with other peroxides, for example dlperoxyesters or diperoxycarbonates, a wide range of reactivities can be achieved. The average life time of the mixture of the different peroxides
usually lies between the half-life of each of the pure peroxides. This is useful for example in ethylene polymerization, where the efficiency
