<Evaluation of transparency>
FIG. 1 is a cross-sectional view of a laminate produced in the evaluation of transparency, and FIG. 2 is a diagram for explaining a point of measuring the transmittance in the evaluation of transparency of an example, and the sample is above. It is a figure seen from. First, 3 mm of a propylene random copolymer (load 2.16 kg, melt flow rate 12 g / 10 min at a measurement temperature of 230 ° C., product name "Prime Polypro R720" manufactured by Prime Polymer Co., Ltd.) on the first cover glass 1. A square film 2 having a size of × 3 mm × 300 μm was placed. Next, about 0.05 mg of the above-mentioned clearing agent 3 was placed in the central portion on the film 2. Further, the second cover glass 4 was placed on the clearing agent 3 to obtain a laminated body 10. The laminate 10 thus obtained is placed on a hot stage with a temperature control function with the surface formed of the first cover glass 1 facing down, and then a 1 g weight is placed on the upper surface of the second cover glass 4. As a result, the laminated body 10 was pressed uniformly. Subsequently, the pressed laminate 10 is heated from room temperature to 220 ° C. at a rate of 100 ° C./min using a heater of a hot stage, held at 220 ° C. for 3 min, and then cooled to room temperature at 100 ° C./min. bottom. The laminate after the heat treatment was used as the sample 20, and the light transmittance when the sample 20 was placed between the two polarizing plates placed on the cloth Nicol was measured to measure Examples 1 to 8 and Comparative Examples 1 to 1. The transparency of the molded product made of the resin composition containing the clearing agent of No. 2 was evaluated. Specifically, using a microultraviolet visible spectrophotometer (MSV-5100 manufactured by JASCO Corporation), the measurement wavelength was set to 500 nm, the IN aperture was set to 30 μm, and the OUT aperture was set to 100 μm, and the first polarizing plate (polarized light) was set from the light source. The intensity I of the light passed through the sample 20 and the second polarizing plate and detected by the detector was measured, and the transmittance T (%) was calculated.

The transmittance T (%) was calculated as follows. That is, the intensity of light when the measurement is performed by arranging only the first polarizing plate (polarizer) without arranging the sample and the second polarizing plate (photometer) is set to I ₁₀₀ , and the sample and the second polarizing plate (photometer) are arranged. Light when the first polarizing plate (polarizer) is placed and the black plate is placed instead of the second polarizing plate (photometer) to perform the measurement without arranging the polarizing plate (photometer) of the above. The transmittance T (%) was calculated from the following formula, _{where I 0} was set to the intensity of.
T (%) = 100 x (I-I ₀ ) / (I _100- I ₀ )

As shown in FIG. 2, in the central portion of the sample 20, particles 5 of the clearing agent that have been melt-solidified and aggregated are present. Straight line passing through the center point O of the point A and the particles of the outer edge of the particle, set the measurement points X _{1 ~} X ₃₀ 30 points at 30μm intervals toward the point A on the outside of the particle, the above conditions The transmittance T (%) was measured. Here, the measured value of the transmittance T (%) at the measurement point _X 1 _{~ X 30} and _Y 1 _{~ Y 30,} respectively. _{The average mi} = (Y _i + Y _{i + 1} + Y _{i + 2} ) / 3 (i = 1 to 28) of the measured values of the transmittance T (%) at the three adjacent measurement points _{was calculated, and the calculated m 1} to m. _{The smallest value among 28} is used as an index of the transparency of the molded product composed of the resin composition containing the clearing agents of Examples 1 to 8 and Comparative Examples 1 and 2, and "Transmittance (%)) is shown in Tables 1 and 2. It was shown as. The value of the transmittance T (%) when the laminate was prepared in the same manner as above except that the transparent agent 3 was not arranged, the heat treatment was performed in the same manner as above, and then the same measurement as above was performed. , 60-70%.

The reason why the measured value of the transmittance obtained as described above serves as an index of the transparency of the molded product made of the resin composition containing the transparent agent is as follows. That is, in the above measurement, when the light from the light source polarized by the first polarizing plate (polarizer) is incident on the sample and the incident light is scattered by the coarse crystals of the polyolefin resin in the sample, the scattered light Since the plane of polarization rotates, the scattered light passes through the second polarizing plate (photometer) and is detected by the detector. On the other hand, when the incident light is not scattered in the sample, the incident light is blocked by the detector and is not detected by the detector. Therefore, it can be said that the smaller the measured value of the transmittance in the above measurement, the smaller the ratio of the scattered light to the total incident light. Therefore, it can be said that the smaller the measured value of the transmittance in the above measurement, the more excellent the transparency of the molded product made of the resin composition containing the transparent agent.

From the results shown in Tables 1 and 2, it was found that the clearing agents of Examples 1 to 8 can impart excellent transparency to the molded product. On the other hand, the clearing agents of Comparative Examples 1 and 2 could not be said to be able to impart sufficient transparency to the molded product.

From the above, it was confirmed that the transparent agent of the present invention can impart excellent transparency to the molded product.
