[0016] Hereinafter, an embodiment of the present invention will be described in detail. First, a resin composition according to the present embodiment will be described.

[0017] <Resin Composition> The resin composition of the present embodiment includes a crystalline resin, a first compound, and a second compound different from the first compound, wherein the first compound and the second compound include a group represented by the following general formula (1), and the number T of triazine rings included in the first compound is １ and the number T of triazine rings contained in the second compound ２ But, T １ <T ２ It satisfies the following.

[0018]

[0019] Here, in the general formula (1), X １ , X ２ and X ３ each independently represents an unsubstituted or substituted phenylene group, and *, **, and *** represent a bonding site to another atom.

[0020] In the resin composition of this embodiment, the crystallinity of the crystalline resin is improved.

[0021] The reason why the crystallinity of the crystalline resin in the resin composition of this embodiment is improved is not entirely clear, but is speculated as follows. That is, since both the first compound and the second compound contain a triaryloxytriazine skeleton, each compound alone has the effect of improving the crystallinity of the crystalline resin. Meanwhile, since both the first compound and the second compound contain a triaryloxytriazine skeleton and have similar structures, the first compound and the second compound may form a co-crystal. When the resin composition of this embodiment is cooled from a molten state, at least a portion of the first compound and at least a portion of the second compound form a co-crystal in the molten crystalline resin. This co-crystal exhibits a stronger crystallinity-improving effect than either the first compound or the second compound alone. Therefore, it is speculated that the resin composition of this embodiment has significantly improved crystallinity.

[0022] 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 crystalline resin may be contained alone or in combination of two or more. Furthermore, the crystalline resin may be a copolymer or a polymer alloy.

[0023] From the viewpoint of obtaining a resin composition in which the crystallinity of the crystalline resin is further improved, the crystalline resin preferably contains a polyolefin-based resin. Examples of polyolefin-based resins include polyethylene-based resins such as low-density polyethylene, linear low-density polyethylene, high-density polyethylene, cross-linked polyethylene, and ultra-high molecular weight polyethylene; polypropylene-based resins such as homopolypropylene, random copolymer polypropylene, block copolymer polypropylene, impact copolymer polypropylene, high-impact copolymer polypropylene, and maleic anhydride-modified polypropylene; α-olefin polymers such as polybutene-1, cycloolefin polymer, poly-3-methyl-1-butene, poly-3-methyl-1-pentene, and poly-4-methyl-1-pentene; and α-olefin copolymers such as ethylene-methyl methacrylate copolymer and ethylene-vinyl acetate copolymer. Here, the molecular weight, degree of polymerization, density, softening point, proportion of insoluble matter in solvent, degree of stereoregularity, presence or absence of catalyst residue, type and blending ratio of raw material monomers, and type of catalyst used in polymerization (e.g., Ziegler catalyst, metallocene catalyst, etc.) of the polyolefin-based resin are not particularly limited and may be selected appropriately.

[0024] From the viewpoint of obtaining a resin composition having further improved crystallinity of the crystalline resin, in the resin composition of this embodiment, the crystalline resin preferably contains at least one selected from the group consisting of polyethylene-based resins and polypropylene-based resins, and more preferably contains a polypropylene-based resin. Furthermore, from the viewpoint of improving the transparency of a molded article made from the resin composition, in the resin composition of this embodiment, the crystalline resin preferably contains a random copolymer polypropylene.

[0025] The resin composition of this embodiment may contain a resin other than the crystalline resin as a resin component, as long as the effect of improving the crystallinity of the crystalline resin is not impaired. Examples of resins other than the crystalline resin include amorphous thermoplastic resins such as polycarbonate resins, styrene-based resins, acrylic resins, urethane-based resins, halogen-containing resins, petroleum resins, coumarone resins, polyvinyl alcohol, polyvinyl acetate, and polyphenylene oxide, and thermosetting resins such as phenolic resins, urea resins, melamine resins, epoxy resins, unsaturated polyester resins, and synthetic rubber. Here, in the resin composition of this embodiment, the content ratio of the crystalline resin relative to the total resin components contained in the resin composition is not particularly limited and can be, for example, 5 to 100% by mass. From the viewpoint of obtaining a resin composition in which the crystallinity of the crystalline resin is further improved, the content of the crystalline resin relative to the total resin components contained in the resin composition is preferably 50 to 100 mass%, more preferably 80 to 100 mass%, even more preferably 90 to 100 mass%, even more preferably 95 to 100 mass%, and particularly preferably 100 mass%.

[0026] The resin composition of this embodiment may contain an elastomer as a resin component, provided that the effect of improving the crystallinity of the crystalline resin is not impaired. In this case, molded articles made from the resin composition will have excellent impact resistance. Examples of elastomers include synthetic rubbers such as isoprene rubber, butadiene rubber, acrylonitrile-butadiene copolymer rubber, styrene-butadiene copolymer rubber, fluororubber, and silicone rubber, as well as thermoplastic elastomers such as polyolefin-based thermoplastic elastomers, polystyrene-based thermoplastic elastomers, polyvinyl chloride-based thermoplastic elastomers, polyurethane-based thermoplastic elastomers, polyester-based thermoplastic elastomers, and polyamide-based thermoplastic elastomers. Among these, thermoplastic elastomers are preferred from the viewpoints of improving the processability of the resin composition and reducing the weight of molded articles made from the resin composition. Furthermore, among thermoplastic elastomers, polyolefin-based thermoplastic elastomers are particularly preferred. When the resin composition of the present embodiment contains an elastomer, the content ratio of the elastomer relative to all the resin components contained in the resin composition is not particularly limited and can be, for example, 1 to 50 mass %, and from the viewpoint of achieving both impact resistance and rigidity in a molded article made from the resin composition, it is preferably 5 to 30 mass %, and more preferably 10 to 25 mass %.

[0170]

[0171] (Examples 1 to 4 and Comparative Examples 1 to 5) 100 parts by mass of random copolymer polypropylene (MFR = 12 g / 10 min at 230 ° C. and a load of 2.16 kg, product name "Prime Polypro R720" manufactured by Prime Polymer Co., Ltd.) were blended with 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, 0.05 parts by mass of calcium stearate, and the resin additive compositions 1 to 8 prepared as described above in the blending amounts shown in Table 2 below, and the mixtures were uniformly mixed to obtain mixtures. The mixture thus obtained was fed into a twin-screw extruder (a Labo Plastomill Micro equipped with a small twin-screw segment 2D15W manufactured by Toyo Seiki Seisaku-sho, Ltd.), 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 to obtain the resin compositions of Examples 1 to 4 and Comparative Examples 1 to 5. In Table 2, the blend amounts of resin additive compositions 1 to 8 are expressed in parts by mass.

[0172] <Characteristics Evaluation> The crystallization temperatures of the resin compositions of Examples 1 to 4 and Comparative Examples 1 to 5 were measured by differential thermal analysis and used as an index of the crystallinity of the resin compositions. Specifically, pellets of the resin compositions 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 (°C). The results are also shown in Table 2.

[0173]

[0174] From the above, it was confirmed that the resin composition of the present invention has improved crystallinity of the crystalline resin.
