The present invention relates to a polymerization catalyst composition containing an organic peroxide. Organic peroxides have -O-O- bonds in their molecules,
It is well known that it is used as a radical source, that is, as a polymerization initiator, in radical polymerization because it thermally decomposes at relatively low temperatures and easily generates free radicals. Generally, this compound is stable at room temperature and is used in the polymerization and copolymerization of olefins and vinyl monomers, as well as in the curing of unsaturated polyesters. It has the disadvantage that it decomposes or explodes if mixed with other substances, and it is far more sensitive to this explosion than picric acid, TNT, etc. Since organic peroxides are dangerous to handle, they are used diluted with dioctyl phthalate, dibutyl phthalate, etc., and diluted with pure products such as calcium sulfate, calcium carbonate, dibasic calcium phosphate, water, etc. However, in the polymerization catalyst composition obtained in this way, the peroxide gradually decomposes over time, and not only good polymerization efficiency cannot be obtained, but also the diluent remains in the polymerization product.
In order to obtain a highly pure product, further purification or drying of the polymerized product was required. An object of the present invention is to provide a polymerization catalyst composition that improves storage stability and polymerization efficiency and does not require purification or drying of the polymerized product. That is, the composition of the present invention mainly contains an organic peroxide and an aliphatic hydrocarbon having a kauributanol value of 30 or less. The aliphatic hydrocarbon with a kauributanol value of 30 or less used in the present invention has the general formula CnH 2o+2 (where n=
8 to 15), specific examples of which include isooctane, isononane, isodecane, isododecane, isoundecane, n-octane, n-nonane, n-decane, n-dodecane, n-undecane, or mixtures thereof. Can be mentioned. Commercially available products include Isopar G, Isopar H, Isopar L, Isopar M, and Isopar K manufactured by Exxon, and Ciel Sol 71 and Ciel Sol T manufactured by Shell Oil. These aliphatic hydrocarbons are odorless, inert liquids with high boiling points and high flash points, and do not contain any impurities such as acids or alkalis. Therefore, there is no risk that the peroxide will decompose or explode due to these aliphatic hydrocarbons. Furthermore, the storage stability of the peroxide can be significantly improved. Furthermore, in various polymerization methods such as exothermic reactions such as bulk polymerization, it is well miscible with peroxides and the decomposition rate of radicals is appropriately controlled, so that polymers can be produced with high polymerization efficiency. Furthermore, since this aliphatic hydrocarbon does not remain in the polymerized product, it has the advantage that purification or drying can be omitted. Note that aliphatic hydrocarbons with a Kauributanol value exceeding 30 have drawbacks such as lowering the electrical resistance value of the resin and increasing the solubility of the resin. On the other hand, all conventionally used organic peroxides can be used, such as ketone peroxides such as methyl ethyl ketone peroxide and cyclohexane peroxide;
-butylperoxy)cyclohexane, peroxyketals such as n-butyl-4,4-bis(t-butylperoxy)valerate; dialxyl peroxide; benzoyl peroxide, succinic peroxide, decanoyl peroxide,
Diacyl peroxide such as 2,4-dichlorobenzoyl peroxide; 2,5-dimethyl-
2,5-di(benzoylperoxide)hexane, t-butylperoxymaleic acid, t-butylperoxyisopropyl carbonate, di-t
Examples include peroxy esters such as -butyl diperoxy phthalate. In the composition of the present invention, the weight ratio of organic peroxide/aliphatic hydrocarbon is generally about 30-90/70-10, preferably about 50-75/50-25 for the above-mentioned purposes. Furthermore, the composition of the present invention can be applied to polymerization reactions such as emulsion polymerization, bulk polymerization, and solution polymerization. In this case, it is usually 0.05 to 2.0wt relative to the monomer.
%used. Examples are shown below. Example 1 2,4-dichlorobenzoyl chloride 500g
and 200 g of isooctane are placed in a four-necked flask and mixed. Next, 4g of monoethanolamine was added and reacted at 80℃ for 2 hours, followed by 100g of hydrogen peroxide.
was added dropwise over 5 hours, and the mixture was further reacted at 80°C for 10 hours to oxidize 2,4-dichlorobenzoyl chloride with hydrogen peroxide. After washing this with water in a separatory funnel, the water was separated to obtain a polymerization catalyst composition (peroxide concentration: 70.53%) consisting of 2,4-dichlorobenzoyl peroxide and isooctane. Further, as Comparative Example 1, a polymerization catalyst composition was obtained in the same manner as in the present Example except that ioctane was removed, and the composition was washed with water and then dried under reduced pressure. Next, the peroxide content and active oxygen amount of these compositions were measured immediately after preparation and after storage at room temperature for 6 months, and the results are shown in Table 1.

[Table] As can be seen from Table 1, the products of the present invention show less change over time in the peroxide content and amount of active oxygen than the comparative products, and therefore have excellent storage stability. It should be noted that there was no fear of explosion in the product of the present invention. Example 2 500 g of benzoyl chloride and 200 g of isodecane were added to 4
Transfer to a neck flask and mix. Add 1 pyridine to this
After reacting at 85° C. for 4 hours, 200 g of hydrogen peroxide was added dropwise over 3 hours, and the reaction was further continued for 5 hours to oxidize benzoyl chloride with hydrogen peroxide. After washing this with water in a separatory funnel, water was separated to obtain a polymerization catalyst composition (peroxide concentration: 30%) consisting of benzoyl peroxide and isododecane. On the other hand, as Comparative Example 2, 98% pure benzoyl peroxide was prepared. These compositions were then tested for explosive properties. First, a beaker containing 500g of the product of the present invention (5
capacity) and a beaker containing 350g of comparative product (5
Prepare 3 beakers each with a capacity of 700°C.
When brought close to a far-infrared heater heated to a temperature of 100%, all comparative products exploded instantaneously, whereas none of the inventive products exploded. Examples 3 to 8 In Example 1, the peroxides and aliphatic hydrocarbons or diluents listed in Table 2 were used to obtain polymerization catalyst compositions having peroxide concentrations shown in the table. The amounts of these active oxygens are shown in Table-3.
