[0025] (crystalline resin) The crystalline resin contained in the resin composition of this embodiment is not particularly limited, and examples of the crystalline resin include polyolefin resins, polyamide resins, polyester resins, polyacetal resins, polylactic acid, and polyphenylene sulfide.

The resulting solution was cooled in an ice bath, and a solution of 3.5 g of 4-cyclohexylphenol and 0.8 g of sodium hydroxide dissolved in 100 mL of distilled water was added dropwise while stirring. The addition rate was adjusted so that the temperature of the reaction solution remained below 10°C during the addition. After the addition was completed, the ice bath was removed, and the reaction solution was stirred at room temperature for an additional hour. After stirring, 100 mL of distilled water was added to the reaction solution to precipitate a precipitate.

[0188] <Preparation of Resin Composition> Example 1 Random copolymer polypropylene (MFR = 12 g / 10 min at 230 ° C and a load of 2.16 kg, Prime Polymer Co., Ltd., product name "Prime Polypro R720") was mixed with 100 parts by mass of 0.03 parts by mass of resin additive composition 1, 0.05 parts by mass of tetrakis[methylene-3-(3',5'-tert-butyl-4'-hydroxyphenyl)propionate]methane, 0.1 parts by mass of tris(2,4-di-tert-butylphenyl)phosphite, and 0.05 parts by mass of calcium stearate. The mixture was mixed at 1000 rpm for 1 minute using an FM mixer (Mitsui Mining Co., Ltd., FM200). The mixture was then fed into a twin-screw extruder (Japan Steel Works, Ltd., TEX-28V), melt-kneaded at a melt temperature of 230 ° C and a screw speed of 150 rpm, and then granulated to obtain pellets. The obtained pellets were dried at 60° C. for 8 hours, and this was used as the resin composition of Example 1.

[0189] (Examples 2 to 237) Except for the fact that resin additive composition 1 was replaced with the resin additive composition corresponding to each example number (i.e., resin additive composition 2 for Example 2, resin additive composition 3 for Example 3, and so on), all other conditions were the same as in Example 1, and resin compositions of Examples 2 to 237 were obtained.

[0190] (Examples 238 to 474) Resin compositions of Examples 238 to 474 were obtained under the same conditions as in Examples 1 to 237, except that the blending amount of resin additive compositions 1 to 237 was changed to 0.05 parts by mass.

[0191] (Examples 475 to 711) Resin compositions 475 to 711 were obtained under the same conditions as in Examples 1 to 237, except that the blending amount of resin additive compositions 1 to 237 was changed to 0.1 parts by mass.

[0192] (Examples 712 to 948) Resin compositions of Examples 712 to 948 were obtained under the same conditions as in Examples 1 to 237, except that the blending amount of resin additive compositions 1 to 237 was changed to 0.15 parts by mass.

[0193] (Examples 949 to 1185) Resin compositions of Examples 949 to 1185 were obtained under the same conditions as in Examples 1 to 237, except that the blending amount of resin additive compositions 1 to 237 was changed to 0.2 parts by mass.

[0194] (Comparative Example 1) The resin composition of Comparative Example 1 was obtained under the same conditions as in Examples 1 to 237, except that the resin additive composition was not blended.

[0195] (Examples 1186 to 2370) Except for the fact that homopolypropylene (MFR=8 g / 10 min at 230°C and a load of 2.16 kg) was used instead of random copolymer polypropylene, all other conditions were the same as in Examples 1 to 1185, and resin compositions of Examples 1186 to 2370 were obtained.

[0196] (Comparative Example 2) A resin composition of Comparative Example 2 was obtained under the same conditions as in Example 1186, except that the resin additive composition was not blended.

[0197] <Characteristics evaluation> The crystallization temperatures of the resin compositions of Examples 1 to 2370 and Comparative Examples 1 and 2 were measured by differential thermal analysis and used as an index for evaluating the crystallinity of the crystalline resin in the resin composition. Specifically, pellets of the resin composition were introduced into a differential scanning calorimeter (Diamond, manufactured by PerkinElmer), and the temperature was raised from room temperature to 230°C at a rate of 50°C / min under a nitrogen atmosphere, held for 20 minutes, and then cooled to 50°C at -10°C / min. The peak-top temperature of the exothermic peak during the cooling process was taken as the crystallization temperature, and the crystallinity of the crystalline resin in the resin composition was evaluated based on this crystallization temperature.

[0198] As a result, it was found that the crystallization temperatures of the resin compositions of Examples 1 to 1185 were higher than that of the resin composition of Comparative Example 1. That is, it was revealed that the resin compositions of Examples 1 to 1185 had improved crystallinity of the crystalline resin compared to the resin composition of Comparative Example 1. It was also found that the crystallization temperatures of the resin compositions of Examples 1186 to 2370 were higher than that of the resin composition of Comparative Example 2. That is, it was revealed that the resin compositions of Examples 1186 to 2370 had improved crystallinity of the crystalline resin compared to the resin composition of Comparative Example 2.

[0199] From the above, it was confirmed that the resin composition of the present invention has improved crystallinity of the crystalline resin.
