[0001] The present invention relates to curable reactors and isohexide-based organic compounds containing silyl ether linkages, methods for their preparation, and curable compositions containing the same. [Background technology]
[0002] As the demand for low-carbon and environmentally friendly materials to respond to climate change and achieve sustainable growth increases, active efforts are being made to replace conventional petroleum-based plastics with bio-based plastics.

However, while the currently realized isohexide-based plastics meet the demand for low-carbon and environmental friendliness, they do not have revolutionary properties compared to conventional petrochemical-based plastics, and there is a problem that they are difficult to apply to advanced material fields such as displays and semiconductors.

[0034] Figures 1 and 2 are example graphs comparing the properties of conventional petrochemical-based plastics and bioplastics.
[0035] Among conventional petrochemical-based plastics, bisphenol resins in particular have excellent strength and heat resistance and are used in many fields, but there is an increasing demand for environmentally friendly bioplastics due to concerns that they may cause endocrine disruption. Also, in order to comply with low-carbon policies such as the Carbon Border Adjustment System for carbon neutrality, there is an increasing need to replace conventional petrochemical-based plastics with bioplastics, and isohexide-based bioplastics are emerging as an alternative as part of this effort.
[0036] Isohexide-based bioplastics include isohexide-based epoxy resins based on isohexides derived from corn starch.
[0037] Referring to FIG. 1, the properties of a petrochemical-based plastic, bisphenol epoxy resin (DGEBA) and an amine toughening agent (DETA), and an isohexide-based plastic, isosorbide-based epoxy resin (DGEI) and an isosorbide-based amine toughening agent (ISODA), are shown.
[0038] The graph in Figure 1 is a graph showing the results of dynamic mechanical analysis (DMA) of DGEBA / DETA (diglycidyl ether of bisphenol A / diethylenetriamine), DGEBA / ISODA (diglycidyl ether of bisphenol A / isosorbide diamine), DGEI / ISODA (diglycidyl ether of isosorbide / isosorbide diamine), and DGEI / DETA (diglycidyl ether of isosorbide / diethylenetriamine). The y-axis of the graph in Figure 1 is storage modulus (MPa) and the x-axis is temperature (°C). Referring to Figure 1, the elastic modulus of DGEBA / ISODA, DGEI / DETA, and DGEI / ISODA containing isohexide-based plastics drops sharply at temperatures significantly lower than that of DGEBA / DETA.
[0039] Referring to Figure 2, the properties of a petrochemical-based plastic, bisphenol epoxy resin (DGEBA) and an amine toughening agent (DETA), and an isohexide-based plastic, isosorbide-based epoxy resin (DGEI) and an isosorbide-based amine toughening agent (ISODA), are shown. The graph in Figure 2 shows the results of thermogravimetric analysis (TGA) of DGEBA / DETA, DGEBA / ISODA, DGEI / ISODA, and DGEI / DETA.
[0040] Referring to the graph in FIG. 2, the weight percent pyrolyzed by temperature is shown.
[0041] The y-axis of Figure 2 is weight (%) and the x-axis is temperature (°C). The temperature at which 5% by weight pyrolysis occurs is the highest for DGEBA / DETA, a petrochemical-based plastic, followed by DGEI / DETA, DGEBA / ISODA, and DGEI / ISODA, which contain isohexide-based plastics, in that order.
[0042] Referring to Figures 1 and 2, the thermal and physical properties of conventional petrochemical-based plastics are superior to conventional bioplastics.
[0043] The organic / inorganic compounds according to the present invention are silyl ether isohexide-based organic / inorganic compounds.
[0044] The organic / inorganic compound according to the present invention contains a molecular structure derived from an isohexide having a silyl ether group and a curable reactive group.

If d is more than 0.3, the chemical reaction may be excessive, causing gelation. If e is less than 0.1, the amount of biocarbon derived from isohexides is low, so that it may be difficult to comply with environmentally friendly policies. If it is more than 0.9, the amount of silane compounds capable of forming silyl ether bonds with isohexides is relatively small, so that synthesis may not be possible.

[0051] The isohexide-based organic or inorganic compound according to the present invention may contain an intramolecular silyl ether bond and may further contain a siloxane bond, thereby realizing superior thermal and mechanical properties compared to conventional isohexide-based organic or inorganic compounds. In this case, the organic or inorganic compound satisfies the following formula 2. As part of the molecular structure in one embodiment, the silyl ether bond and the siloxane bond respectively represent a Si-OC bond and a Si-O-Si bond as shown in formula 2 below. [ka]
[0052] In the above formula 2, x includes the curable reactive group and the carbon compound, and n is a positive number.
[0053] The X satisfies the following formula 3.

[0057] Reacting the silane compound with an isohexide involves forming a silyl ether bond through a condensation reaction.
[0058] The silane compound is selected from the group consisting of the following formulas 4 to 7, or a combination thereof.

[0136] Examples 1 to 14 and Comparative Examples 1 to 3 show synthetic products obtained by reacting isohexide with combinations of silane compounds represented by Chemical Formula 4, Chemical Formula 5, Chemical Formula 6, and Chemical Formula 7, and the molar ratios of each reactant to the total reactants are summarized in Table 1 below.
[0137] [Table 1]
[0138] In this case, if the molar ratio of the silane compounds of the formulas 4, 5, and 6 to the total reactants is defined as f, the molar ratio of the silane compound of the formula 7 to the total reactants is defined as g, and the molar ratio of the isohexide to the total reactants is defined as h, then it was confirmed that in Examples 1 to 14, 0.1≦f≦0.9, 0≦g≦0.3, and 0.1≦h≦0.9 were satisfied, and the synthesis was well performed and the biocarbon content was 20% or more, so that it can meet the environmentally friendly policy regarding bio-based plastics. On the other hand, in the case of Comparative Example 1 where f<0.1 and h>0.9, it was confirmed that the synthesis was not performed well and phase separation occurred because the amount of silane compounds capable of forming a silyl ether bond with isohexide was relatively small. In addition, in the case of Comparative Example 2 where f>0.9 and h<0.1, it was confirmed that the biocarbon content was about 11.5%, which is less than 20%, and therefore does not meet the standard for bio-based plastics. In the case of Comparative Example 3 where g>0.3, it was confirmed that the condensation reaction proceeded excessively, resulting in gelation.
