1827 (1942), etc. R 1 in formula [2] is preferably a lower alkyl group having about 1 to 4 carbon atoms. This is because the larger the alkyl group, the higher the boiling point of the compound, making isolation and purification by distillation more difficult.
The novel compound [1] of the present invention is prepared by combining tris(hydroxymethyl)nitromethane and compound [2] with a suitable solvent, such as di-n-octyl phthalate,
It is produced by dealcoholization in a solvent such as di-n-butyl phthalate in the presence of a catalyst such as p-toluenesulfonic acid. The degree of progress of the reaction can be determined not only by measuring the amount of alcohol distilled out, but also by analyzing the reaction solution using, for example, liquid chromatography. The charging ratio of compound [2] and tris(hydroxymethyl)nitromethane may be equimolar or a slight excess of one of them, and the reaction is generally carried out under heating in an inert gas atmosphere such as nitrogen gas at a mole of 80 to
It is appropriate to carry out the test at about 160°C. Compound [1] can be separated from the reaction product by vacuum distillation or recrystallization depending on its physical properties. Some of the bicycloorthoesters to which the compound [1] of the present invention belongs are described by WJ Bailey and K.

(1980) etc. Although the compound of the present invention undergoes ring-opening polymerization like the compound described in the above-mentioned literature, we have obtained the unexpected finding that it not only undergoes ring-opening polymerization, but also has a larger volumetric expansion due to polymerization than the compounds described in such literature. It is believed that the polymerization of the compound according to the present invention proceeds by the following mechanism. (In the formula, X represents a nitro group.) The cationic polymerization of the compound [1] of the present invention is carried out by a generally well-known method, that is, by ultraviolet rays, infrared rays, heat, microwaves, etc. in the presence of a cationic polymerization initiator.

Dicarbonyl complex compounds of elements of groups a-a of the periodic table, such as the following formula, may be used. The amount of catalyst used is generally 0.001 to 10 wt%, preferably 0.1 to 5 wt%, based on the monomer to be polymerized.
A range of is suitable. Although there are no particular restrictions regarding the polymerization temperature, it is usually carried out at room temperature to 200°C. When using a solvent during polymerization, it is desirable to choose a compound that does not react with the growing cation and reduce its activity. Suitable solvents for use include aliphatic hydrocarbons such as hexane and octane; aromatic hydrocarbons such as toluene and xylene; halogenated hydrocarbons such as methylene chloride, 1,1-dichloroethane, and others. During the polymerization of compound [1], the bicycloorthoester ring opens as shown in the above reaction formula, and ether and ester bonds are formed to give a polymer. As shown in Table 1 below, conventional cationic polymerizable monomers undergo extremely large volumetric contraction during polymerization.

[Table] If the volumetric shrinkage during polymerization is large, for example, when used as a molding material, dimensional accuracy may be poor, when used as a casting material, distortion may occur due to filler material, or there may be problems with the mold. There are problems such as a decrease in adhesive strength and the formation of gaps. In addition, when used as a paint, internal strain may cause a decrease in adhesion to the painted plate and warping, and when used as an adhesive, internal strain may cause problems such as a decrease in adhesive strength, warping, and deformation. . On the other hand, when determining the volume change when a compound according to the present invention, such as compound [1], is cationically polymerized, it is found that 1-methyl-4-nitro-2,6,7-trioxabicyclo[2,2, 2] Octane has a volumetric expansion rate of about 4.5%, and 1-ethyl-4-nitro-2,6,7-trioxabicyclo[2,
2,2] Octane has a volumetric expansion rate of about 7.4%,
Surprisingly, volumetric expansion was observed. The known compounds of the formula below, which are closest to compound [1] and compound [2], do not exhibit volumetric expansion during cationic polymerization; in contrast, compound [1] exhibits volumetric expansion during polymerization as described above. The truth is truly unexpected. The volumetric shrinkage rate (%) is [1 - (specific gravity of the compound/specific gravity of the polymer obtained from the compound)] x 100, and the volumetric expansion rate (%) is [(specific gravity of the compound/specific gravity of the polymer obtained from the compound)] specific gravity)-1]×100. As mentioned above, the compound [1] of the present invention can be easily produced and has the advantage of expanding in volume upon polymerization. Therefore, the compound [1] of the present invention is an extremely useful compound for use in molding materials, composite materials, adhesives, casting materials, paints, etc. EXAMPLES The present invention will be explained in more detail and concretely by showing Examples and Reference Examples below. Example 1 45.3 g (0.3 mol) of tris(hydroxymethyl)nitromethane and 48.8 g (0.33 mol) of triethyl orthoformate were placed in a three-necked flask equipped with a water content receiver, a stirrer, and a nitrogen blowing tube equipped with a condenser.

The reaction was further carried out at 150° C. for 5 hours to obtain about 16.5 g of distillate whose main component was ethyl alcohol. 0.6 ml of triethylamine was added to this reaction solution to neutralize the catalyst. Next, distillation was carried out under reduced pressure while heating the distillation tube with a ribbon heater to prevent precipitation of crystals, yielding a pale yellow solid. This solid was purified by recrystallization using an acetone-n-hexane system,

The reaction was continued at this temperature for 4 hours, and about 71 g of a distillate containing ethanol as a main component was obtained. 0.6 ml of triethylamine was added to this reaction solution to neutralize the catalyst. Next, distillation was carried out under reduced pressure while heating the distillation tube with a ribbon heater to prevent precipitation of crystals, yielding 62.7 g of a pale yellow solid.

[the same applies to each of the following examples]. Example 3 In an apparatus similar to Example 1, 90.6 g (0.6 mol) of tris(hydroxymethyl)nitromethane, 116.2 g (0.66 mol) of triethyl orthopropionate, 240 g of di-n-octyl phthalate, and p-toluenesulfonic acid were added. 0.6 g was charged, and the temperature was gradually raised to 140° C. while stirring and passing nitrogen gas. The reaction was continued at this temperature for 4 hours to obtain about 65 g of a distillate whose main component was ethanol. 1.2 ml of triethylamine was added to this reaction solution to neutralize the catalyst. Next, vacuum distillation was carried out while heating the distillation tube with a ribbon heater to prevent precipitation of crystals, yielding about 107 g of a pale yellow solid. This solid is n-
Recrystallization purification with hexane was performed to obtain 41.0 g (yield 36%) of white crystalline 1-ethyl-4-nitro-2,6,7-trioxabicyclo[2,2,2]octane. The distillation temperature was 110°C/1.5mmHg. The physical properties of this compound are as follows. Γ melting point: 78℃ Γ specific gravity: 1.440/25℃ ΓIR......

As a result, a colored and semi-solid polymer was obtained. The molecular weight of this polymer was about 1000. Further, the specific gravity of the polymer was 1.366 (25°C), and the volumetric expansion rate due to polymerization calculated from this value was about 4.5%. According to IR analysis of this polymer, the peak at 1138 cm -1 disappeared, and peaks at 3400 cm -1 and 1750 cm -1 were generated.
