Abstract
Description
Technical Field
[0001] This invention relates to novel phenolic compounds and their use as stabilizers for organic materials. Background Technology
[0002] It is known that organic materials such as thermoplastic resins, thermosetting resins, natural or synthetic rubbers, mineral oils, lubricants, adhesives, and coatings can deteriorate during manufacturing, processing, and even use due to the effects of heat or oxygen. This deterioration is accompanied by phenomena such as molecular cleavage or cross-linking, which lead to a decrease in the strength and physical properties of organic materials, changes in fluidity, coloring, and a decrease in surface properties. Sometimes, the commercial value can be significantly impaired.
[0003] Various phenolic and phosphorus-based antioxidants have been developed to prevent such heat- or oxygen-induced deterioration, and it is known that adding them to organic materials can stabilize them (Patent Document 1). However, the antioxidants used in the past have sometimes been insufficient in stabilizing the heat- or oxygen-induced deterioration during the processing of organic materials, and compounds with further stabilizing effects are needed.

[0179] Determination of melt flow rate (MFR)
[0180] MFR was determined using a melt indexer (model L246-3537, manufactured by TECHNOLSEVEN CO.,LTD.) at a temperature of 230°C and a load of 21.18 N.
[0181] Polypropylene resin decomposes during thermal processing, increasing its molecular weight ratio (MFR). Therefore, the less likely a polypropylene resin composition with added stabilizers is to experience an increase in MFR due to thermal processing, the better its processing stability.
[0182] Measurement of Yellow Index (YI)
[0183] The particles obtained in the examples and comparative examples were stamped using a stamping press (Kansai Roll Co., Ltd. "PEW-5040") at a temperature of 230°C to obtain sheets with a thickness of 1 mm. The yellow index (YI) of the obtained sheets was measured using a colorimeter (Minolta Co., Ltd. "CM-3500d"). It can be said that the smaller the YI value, the more suppressed the discoloration.
[0184] Example 1: Phenolic compound (R) represented by formula (1) 1 Synthesis of (=methyl)
[0185] Add SUMILIZER (registered trademark) GA-80 (chemical formula: C 43 H 64 O 10 10 g (13.5 mmol) of acetone, 100 mL of potassium carbonate, 1.87 g (13.5 mmol, molecular weight: 138.20) and 1.92 g (13.5 mmol, molecular weight: 141.94) of methyl iodide (MeI) were stirred overnight at room temperature. Since the ratio of reactants to products in LC was approximately 8:2, equal amounts of potassium carbonate and methyl iodide were added to each, and the mixture was stirred at room temperature for 6 hours. After adding equal amounts of potassium carbonate and methyl iodide to each and stirring overnight, the mixture was filtered, and the residue was concentrated to obtain the crude product. The residue was purified by silica gel column chromatography (developing solvent: hexane / ethyl acetate system) to obtain 4.5 g of compound (1) represented by the following formula (1-MeO) and 2.9 g of dimethoxyform (DMeO) represented by the following formula (DMeO). Compound (1), represented by formula (1-MeO), is the phenolic compound of the present invention. The resulting dimethoxylated form was used in the comparative resin composition of Comparative Example 3 described later. It should be noted that the chemical formula of compound (1), represented by formula (1-MeO), is C. 44 H 66 O 10 The exact mass is 754.47, and the molecular weight is 755.00. Furthermore, the chemical formula of the dimethoxyl form represented by (DMeO) is C. 45 H 68 O 10 The exact mass is 768.48, and the molecular weight is 769.03.

[0202] Example 2: Preparation of particles of a resin composition comprising a phenolic compound represented by formula (1)
[0203] 0.05 parts by weight of calcium stearate and 0.1 parts by weight of compound (1) obtained in Example 1 were dry-mixed into 100 parts by weight of polypropylene resin (manufactured by Sumitomo Chemical Co., Ltd., MFR: 25 g / 10 min). Under air conditions, the mixture was kneaded using a twin-screw extruder (model: BTN32-S2-36-L, manufactured by PLABOR Research Laboratory of Plastics Technology Co., Ltd.) with a barrel diameter of 32 mm at a temperature of 230°C and a screw speed of 100 rpm to obtain granules (1) of the resin composition of the present invention.
[0204] In an air environment, the obtained granules (1) were compounded using a single-screw extruder (model: VS30-28, manufactured by Tanabe Plastics Machinery Co., Lid.) with a barrel diameter of 30 mm at a temperature of 280°C and a screw speed of 100 rpm. This operation was repeated 5 times to obtain granules (2) after 5 compounding operations. The MFR and YI of the obtained granules (2) were measured according to the above-described method. The results are shown in Table 1.
[0205] Comparative Example 1
[0206] Except for the absence of compound (1), the process was the same as in Example 2, resulting in granules after 5 mixing operations. The MFR and YI of the granules were measured according to the above-described method. The results are shown in Table 1.
[0207] Comparative Example 2
[0208] Except for the addition of 0.1 parts by weight of GA-80, which was used as a raw material in Example 1, to replace compound (1), the process was carried out in the same manner as in Example 2, and granules were prepared after 5 mixing operations. The MFR and YI of the obtained granules were measured according to the above-described determination method. The results are shown in Table 1.
[0209] Comparative Example 3
[0210] Except for adding 0.1 parts by weight of the dimethoxyl body obtained in the manufacturing method described in Example 1 to replace compound (1), the process was carried out in the same manner as in Example 2 to prepare granules after 5 mixing operations. The MFR and YI of the obtained granules were measured according to the above-described determination method. The results are shown in Table 1.

[0213] For the resin composition of Example 2, the MFR in the particles (2) after five repeated mixing operations was low, confirming that it could suppress resin decomposition, which is believed to be caused by heat, oxygen, etc. during processing. In addition, YI was also low, confirming that it could prevent resin discoloration. In contrast, in Comparative Examples 1 to 3 without the addition of the phenolic compounds of the present invention, the effects of suppressing resin decomposition and preventing discoloration were not sufficiently improved after five mixing operations.
