[0038] (Vinyl chloride resin) The resin serving as the base material of the resin composition is a vinyl chloride resin, which is a polymer having a group represented by -CH2-CHCl-. Such vinyl chloride resins include homopolymers of vinyl chloride monomers as well as copolymers of vinyl chloride monomers and other copolymerizable monomers. Furthermore, the vinyl chloride resin may be a chlorinated vinyl chloride resin.

[0039] Examples of other monomers copolymerizable with vinyl chloride monomer include α-olefins, vinyl esters, vinyl ethers, (meth)acrylic acid esters, aromatic vinyls, N-substituted maleimides, etc. These other monomers may be used in combination.

[0040] The resin serving as the base material of the resin composition is preferably a vinyl chloride resin consisting of a homopolymer, and for example, it is also possible to use two or more kinds of homopolymer vinyl chloride monomers having different degrees of polymerization.

[0041] From the viewpoint of achieving both moldability and bleeding, the vinyl chloride resin preferably contains, as at least a part of, a homopolymer having a polymerization degree of 1000 to 1600, and more preferably contains a homopolymer having a polymerization degree of 1350 to 1500. Here, the average polymerization degree is an average polymerization degree measured in accordance with JIS K-6721 "Testing methods for vinyl chloride resins" using a resin obtained by dissolving a polyvinyl chloride resin in tetrahydrofuran (THF), removing insoluble components by filtration, and then drying and removing the THF in the filtrate, as a sample.

[0042] As the vinyl chloride resin, commercially available products may be used, such as polyvinyl chloride "ZEST1400Z" (average degree of polymerization 1450) from Shin-Daiichi Vinyl Corporation and polyvinyl chloride "TK-1400" (average degree of polymerization 1400) from Shin-Etsu Chemical Co., Ltd.

[0043] In addition to such resins, it is also possible to use vinyl chloride resins made of homopolymers with different properties. Different properties refer to cases where the average polymerization degree is different or the particle size is different. For example, it is also preferable to mix a polyvinyl chloride resin in a fine powder form (particle size of about 100 μm or less).

[0044] A representative example of use is a combination of polyvinyl chloride "ZEST1400Z" (average degree of polymerization 1450) and "ZESTP24Z" (average degree of polymerization 1200 to 1390) manufactured by Shin-Daiichi Vinyl Corporation, but is not limited thereto.

[0045] In the resin composition, the content of the vinyl chloride resin relative to the total amount of the resin composition is preferably 40 mass % or more and 65 mass % or less, more preferably 42 mass % or more and 60 mass % or less, and even more preferably 45 mass % or more and 55 mass % or less.

[0046] When the resin composition contains two or more vinyl chloride resins with different degrees of polymerization, for example, the ratio of ZEST P24Z to ZEST 1400Z is preferably 0.005 parts by mass or more and 0.8 parts by mass or less, more preferably 0.03 parts by mass or more and 0.5 parts by mass or less, and even more preferably 0.05 parts by mass or more and 0.2 parts by mass or less, per 1 part by mass of ZEST 1400Z.

[0047] (pest) Examples of pests include, but are not limited to, fleas (including fleas that infest dogs, cats, etc.), mites (including ticks, chiggers, oribatid mites, scabies mites, and cat mites), or parasitic or blood-sucking pests such as lice, mosquitoes, etc. Particularly preferred pests to be controlled are fleas, mites, mosquitoes, and lice.

[0048] The animals include various animals such as pets, livestock, poultry, etc. In particular, pets such as dogs, cats, rabbits, hamsters, etc., livestock and poultry such as cows, horses, pigs, chickens, etc. are included.

[0049] (Other Ingredients) The resin composition may contain optional components other than fipronil, insect growth regulators, phosphates, and fatty acids in the polyvinyl chloride resin. For example, optional components include pest control components other than fipronil and insect growth regulators, additional plasticizers, stabilizers, pigments, fragrances, etc.

[0050] Examples of the additional plasticizer include one or more selected from the group consisting of diisononyl adipate, diisodecyl adipate, di-2-ethylhexyl azelate, sebacic acid, and 2-ethylhexyl.

[0051] The stabilizer may be, for example, one or more selected from the group consisting of epoxidized soybean oil, barium / zinc-based liquid stabilizer, and barium stearate. It is also desirable to use all of these in combination.

[0052] The resin composition is not limited to the above, and may be a resin composition disclosed in JP-A-2019-14673, JP-A-2020-007238, etc.

[0053] The resin composition may contain, without being limited to the above-mentioned fipronil or etofenprox, one or more selected from, for example, dinotefuran, tetrachlorvinphos, fenothrin, metofluthrin, transfluthrin, allethrin, profluthrin, empenthrin, imidacloprid, selamectin, etc.

[0054] (Method for producing resin composition and molded product) The resin composition can be produced, for example, by the following method, although the method is not limited thereto. First, polyvinyl chloride resin and a pigment are mixed, and other raw materials are mixed separately, and then they are mixed to prepare a mixture. Alternatively, fipronil, polyvinyl chloride resin, and a pigment are mixed, and other raw materials are mixed separately, and then they are mixed to prepare a mixture. The temperature during mixing can be in the range of 1 to 30°C, and the time can be about 1 to 20 minutes. After mixing, the mixture is dried at a high temperature. The temperature at this time is not limited, but it is preferably about 100°C or higher and 150°C or lower. Mixing and heat drying are repeated until the resin dries up. At this time, for example, a Banbury mixer, a super mixer, etc. can also be used.

[0055] Next, the resin composition thus obtained is made into a resin molded body for pest control. At this time, for example, it can be melted and molded. As a manufacturing method of the molded body, a method usually used in molding processing of resin can be used. Such a method includes, for example, extrusion molding, injection molding, blow molding, compression molding, powder molding, press molding, etc. Although not limited, the molded body can be preferably manufactured using an injection molding machine.

[0056] For the purpose of use as a pest control collar, it can be first molded into a belt or band shape, but it is also possible to melt the resin in an injection molding machine or the like and then mold it directly into a shape appropriate for the application. For example, it can be poured into a collar-shaped mold, cooled, and then molded directly into a collar.

[0057] As a non-limiting example, a collar of a specific size can be molded in an injection molding machine with a temperature setting of 138-145°C, an injection time of 2-3 seconds, and a cooling time of 8-15 seconds. Although not limited thereto, typically, the collar can be molded into a shape of a collar with a length of 35 or 60 cm, a width of about 1.0 cm, and a thickness of about 0.3 cm.

[0058] (Resin molding) The resin molded article obtained from the resin composition can be used while being replaced at a frequency of about once every six months or once a year depending on the application, etc. In particular, it can be used at these frequencies as a collar for medium-sized and large-sized dogs.

[0059] It is preferable that the molded article obtained from the resin composition has a good balance between elongation and strength, for example, when measured by a method similar to the measurement method described in the Examples. Although not limited, such a balance is thought to be achieved when the value of elongation (%) / strength (N) of the resin molded article is about 0.5 to 1.5. That is, it is a molded article that has sufficient elongation while maintaining strength, and is suitable for, but not limited to, applications such as collars.
