　本発明は、上記の問題に鑑みてなされたものであり、その目的は、環境負荷を低減した塩化ビニリデン系樹脂、該樹脂を含むラップ、ケーシング、ラテックス、およびバインダー、ならびに、該樹脂の製造方法を提供することである。 The present invention has been made in view of the above problems, and its objects are to provide a vinylidene chloride resin with reduced environmental impact, a wrap, a casing, a latex, and a binder containing the resin, and a method for producing the resin. The goal is to provide the following.
　本発明者らは、再生可能な有機資源由来特性を割り当てられた、塩化ビニリデン系樹脂を用いることによって、環境負荷を低減できることを見出し、本発明を完成するに至った。 The present inventors have discovered that the environmental load can be reduced by using a vinylidene chloride-based resin that has been assigned characteristics derived from renewable organic resources, and have completed the present invention.
　本発明の第１の態様は、再生可能な有機資源由来特性を割り当てられた、塩化ビニリデン系樹脂である。 The first aspect of the present invention is a vinylidene chloride-based resin that is assigned properties derived from renewable organic resources.
　本発明の第２の態様は、第１の態様にかかる塩化ビニリデン系樹脂を含む、ラップである。
　本発明の第３の態様は、第１の態様にかかる塩化ビニリデン系樹脂を含む、ケーシングである。
　本発明の第４の態様は、第１の態様にかかる塩化ビニリデン系樹脂を含む、ラテックスである。
　本発明の第５の態様は、第１の態様にかかる塩化ビニリデン系樹脂を含む、バインダーである。 A second aspect of the present invention is a wrap comprising the vinylidene chloride resin according to the first aspect.
A third aspect of the present invention is a casing comprising the vinylidene chloride resin according to the first aspect.
A fourth aspect of the present invention is a latex comprising the vinylidene chloride resin according to the first aspect.
A fifth aspect of the present invention is a binder comprising the vinylidene chloride resin according to the first aspect.
　本発明の第６の態様は、第１の態様にかかる塩化ビニリデン系樹脂の製造方法であって、再生可能な有機資源由来特性を割り当てられた塩化ビニリデンおよび／または再生可能な有機資源由来特性を割り当てられた塩化ビニルを重合する工程を含む、塩化ビニリデン系樹脂の製造方法である。 A sixth aspect of the present invention is a method for producing a vinylidene chloride-based resin according to the first aspect, which comprises producing vinylidene chloride that has been assigned a characteristic derived from a renewable organic resource and/or a characteristic derived from a renewable organic resource. This is a method for producing vinylidene chloride resin, which includes a step of polymerizing assigned vinyl chloride.
　本発明によれば、環境負荷を低減した塩化ビニリデン系樹脂、該樹脂を含むラップ、ケーシング、ラテックス、およびバインダー、ならびに、該樹脂の製造方法を提供することができる。 According to the present invention, it is possible to provide a vinylidene chloride resin with reduced environmental impact, a wrap, a casing, a latex, and a binder containing the resin, and a method for producing the resin.
　本明細書において、「再生可能な有機資源由来特性を割り当てられた塩化ビニリデン系樹脂」とは、化石資源由来の原料から塩化ビニリデン系樹脂を製造する工程に、再生可能な有機資源由来の原料を混合して製造された塩化ビニリデン系樹脂のうち、マスバランス方式やブックアンドクレーム方式等により再生可能な有機資源由来特性を割り当てられた塩化ビニリデン系樹脂をいう。 In this specification, "vinylidene chloride resin assigned characteristics derived from renewable organic resources" refers to the use of raw materials derived from renewable organic resources in the process of producing vinylidene chloride resin from raw materials derived from fossil resources. Among the vinylidene chloride resins produced by mixing, it refers to vinylidene chloride resins that have been assigned characteristics derived from renewable organic resources through the mass balance method, book-and-claim method, etc.
　「マスバランス方式」は、ＩＳＯ　２２０９５：２０２０で定義される方式であり、原料から製品への加工・流通工程において、ある特性を持った原料（例えば、再生可能な有機資源由来の原料）がそうでない原料（例えば、化石資源由来の原料）と混合される場合に、その特性を持った原料の投入量に応じて、製品の一部に対してその特性の割り当てを行う方式をいう。 The "mass balance method" is a method defined by ISO 22095:2020, in which raw materials with certain characteristics (for example, raw materials derived from renewable organic resources) are used in the processing and distribution process from raw materials to products. This is a method in which when a product is mixed with a raw material that is not derived from fossil resources (for example, a raw material derived from fossil resources), the characteristics are assigned to a part of the product depending on the input amount of the raw material with that characteristic.
　本発明の塩化ビニリデン系樹脂および該樹脂を含む製品（ラップ、ケーシング、ラテックス、およびバインダー）では、再生可能な有機資源由来特性を割り当てられた原料を使用しているため、サプライチェーン全体における化石資源由来の原料の使用量が削減され、環境負荷を低減する効果が得られる。
　また、一部の塩化ビニリデン系樹脂および該樹脂を含む製品に対する割り当て量を高くすることで、塩化ビニリデン系樹脂および該樹脂を含む製品の付加価値を高めることができる。これにより活用が進められる結果、化石資源由来の原料の使用量が削減され、環境負荷を低減する効果が得られる。
　環境負荷を低減する効果としては、具体的には、例えば、温室効果ガスの排出抑制等の環境負荷指標であるＧＨＧ（Ｇｒｅｅｎｈｏｕｓｅ　Ｇａｓ）排出量を低減する効果が挙げられる。 The vinylidene chloride resin of the present invention and products containing the resin (wraps, casings, latex, and binders) use raw materials that are assigned renewable organic resource-derived characteristics, thereby reducing the amount of raw materials derived from fossil resources used throughout the supply chain and achieving an effect of reducing the environmental burden.
In addition, by increasing the allocation amount for some vinylidene chloride resins and products containing the resins, the added value of the vinylidene chloride resins and products containing the resins can be increased, which will promote their utilization and reduce the amount of raw materials derived from fossil resources used, thereby reducing the environmental burden.

　ラップのＧＨＧ排出量は、ラップ１ｋｇに含まれる塩化ビニリデン系樹脂を原料（ナフサおよび／またはバイオナフサ）から製造するまでを範囲としたＧＨＧ排出量（原単位と排出原単位の積）と、ラップ１ｋｇに含まれる他の各配合剤を原料から製造するまでを範囲とした各ＧＨＧ排出量（原単位と排出原単位の積）と、これらの配合剤をラップ１ｋｇに加工してから廃棄（焼却）するまでのＧＨＧ排出量との和である、サプライチェーン全体を範囲としたＧＨＧ排出量（ｋｇＣＯ２ｅｑ）として算出する。例えば、ラップの配合剤が塩化ビニリデン系樹脂と可塑剤である場合、ラップのＧＨＧ排出量は、ラップ１ｋｇに含まれる塩化ビニリデン系樹脂の原単位と排出原単位の積と、ラップ１ｋｇに含まれる可塑剤の原単位と排出原単位の積と、これらの配合剤を加工してから廃棄（焼却）するまでのＧＨＧ排出量との和である。ケーシング、ラテックス、およびバインダーにおけるＧＨＧ排出量（ｋｇＣＯ２ｅｑ）も同様にして算出する。

The GHG emissions of plastic wrap are the GHG emissions (the product of the basic unit and the basic unit of emissions) for the production of vinylidene chloride resin contained in 1 kg of plastic wrap from raw materials (naphtha and/or bio-naphtha), and The amount of GHG emissions (product of basic unit and emission basic unit) covering the range from raw materials to manufacturing of each compounding agent included in 1kg, and the amount of waste (incineration) after processing these compounding agents into 1kg of wrap. ) is calculated as GHG emissions (kg CO 2 eq) covering the entire supply chain. For example, if the ingredients of the wrap are vinylidene chloride resin and a plasticizer, the GHG emissions of the wrap are the product of the basic unit of vinylidene chloride resin contained in 1 kg of wrap and the emission factor, and the product of the emission factor and the vinylidene chloride resin contained in 1 kg of wrap. It is the sum of the product of the plasticizer basic unit and the emission basic unit, and the GHG emissions from processing these compounding agents until they are disposed of (incinerated). GHG emissions (kg CO 2 eq) in the casing, latex, and binder are calculated in the same manner.
For these calculations, we referred to the "Basic Guidelines for Accounting for Greenhouse Gas Emissions Through the Supply Chain" (Ver. 2.4, March 2022, Ministry of the Environment, Ministry of Economy, Trade and Industry) and the literature (C.

＜塩化ビニリデン系樹脂＞
　塩化ビニリデン系樹脂は、再生可能な有機資源由来特性を割り当てられている。これにより、環境負荷を低減できる。 <Vinylidene chloride resin>
Vinylidene chloride resins are assigned properties derived from renewable organic resources. This allows the environmental load to be reduced.
　塩化ビニリデン系樹脂（以下、「ＰＶＤＣ」ということがある。）は、塩化ビニリデンのホモ重合体でもよく、塩化ビニリデン６０質量％以上９８質量％以下と、塩化ビニリデンと共重合可能な他の単量体２質量％以上４０質量％以下との共重合体でもよい。塩化ビニリデンと共重合可能な他の単量体としては、例えば、塩化ビニル；アクリル酸メチル、アクリル酸エチル、アクリル酸ブチル、アクリル酸ラウリル等のアクリル酸アルキルエステル（アルキル基の炭素原子数１以上１８以下）；メタクリル酸メチル、メタクリル酸ブチル、メタクリル酸ラウリル等のメタクリル酸アルキルエステル（アルキル基の炭素原子数１以上１８以下）；アクリロニトリル等のシアン化ビニル；スチレン等の芳香族ビニル；酢酸ビニル等の炭素原子数１以上１８以下の脂肪族カルボン酸のビニルエステル；炭素原子数１以上１８以下のアルキルビニルエーテル；アクリル酸、メタクリル酸、マレイン酸、フマル酸等のビニル重合性不飽和カルボン酸；マレイン酸、フマル酸、イタコン酸等のビニル重合性不飽和カルボン酸のアルキルエステル（部分エステルを含み、アルキル基の炭素原子数１以上１８以下）等が挙げられる。より好ましくは塩化ビニル、アクリル酸メチル、およびアクリル酸ラウリルから選ばれる少なくとも１種、さらに好ましくは塩化ビニルである。塩化ビニリデンと共重合可能な他の単量体は、１種を単独で用いても、２種以上を組み合わせて用いてもよい。塩化ビニリデンの割合は、より好ましくは６５質量％以上９７質量％以下、更に好ましくは７０質量％以上９０質量％以下の範囲である。他の単量体の割合は、より好ましくは３質量％以上３５質量％以下、更に好ましくは１０質量％以上３０質量％以下の範囲である。他の単量体の割合が３質量％以上であると溶融加工性が低下しにくく、他方、他の単量体の割合が３５質量％以下であるとガスバリア性が低下しにくい。また、溶融加工性を向上させるために２種以上のＰＶＤＣを混合してもよい。 The vinylidene chloride-based resin (hereinafter sometimes referred to as "PVDC") may be a homopolymer of vinylidene chloride, which contains 60% by mass to 98% by mass of vinylidene chloride and other monomers copolymerizable with vinylidene chloride. It may also be a copolymer with 2% by mass or more and 40% by mass or less. Other monomers that can be copolymerized with vinylidene chloride include, for example, vinyl chloride; acrylic acid alkyl esters such as methyl acrylate, ethyl acrylate, butyl acrylate, and lauryl acrylate (where the alkyl group has 1 or more carbon atoms). 18 or less); Methacrylic acid alkyl esters such as methyl methacrylate, butyl methacrylate, and lauryl methacrylate (alkyl group has 1 to 18 carbon atoms); Vinyl cyanide such as acrylonitrile; Aromatic vinyl such as styrene; Vinyl acetate Vinyl esters of aliphatic carboxylic acids having 1 to 18 carbon atoms such as; alkyl vinyl ethers having 1 to 18 carbon atoms; vinyl polymerizable unsaturated carboxylic acids such as acrylic acid, methacrylic acid, maleic acid, fumaric acid; Alkyl esters (including partial esters, the alkyl group having 1 to 18 carbon atoms) of vinyl polymerizable unsaturated carboxylic acids such as maleic acid, fumaric acid, and itaconic acid can be mentioned. More preferably at least one selected from vinyl chloride, methyl acrylate, and lauryl acrylate, still more preferably vinyl chloride. The other monomers copolymerizable with vinylidene chloride may be used alone or in combination of two or more. The proportion of vinylidene chloride is more preferably 65% by mass or more and 97% by mass or less, and still more preferably 70% by mass or more and 90% by mass or less. The proportion of other monomers is more preferably 3% by mass or more and 35% by mass or less, and even more preferably 10% by mass or more and 30% by mass or less. When the proportion of other monomers is 3% by mass or more, melt processability is less likely to decrease, while when the proportion of other monomers is 35% by mass or less, gas barrier properties are less likely to decrease. Furthermore, two or more types of PVDC may be mixed to improve melt processability.
　塩化ビニリデン系樹脂において、再生可能な有機資源由来特性を割り当てられた成分量は質量の１０％以上が好ましく、２０％以上がより好ましく、２５％以上がさらに好ましい。上記成分量の上限は特に限定されず、１００％であってもよいが、例えば、８０％以下であってもよく、５０％以下であってもよく、３０％以下であってもよい。
　本明細書において、塩化ビニリデン系樹脂における再生可能な有機資源由来特性を割り当てられた成分量は、各単量体の割合と、各単量体における再生可能な有機資源由来特性を割り当てられた成分量との積を１００で除して得られる値の総和である。 In the vinylidene chloride resin, the amount of the component assigned the renewable organic resource derived characteristic is preferably 10% or more by mass, more preferably 20% or more, and even more preferably 25% or more. The upper limit of the amount of the component is not particularly limited and may be 100%, but may be, for example, 80% or less, 50% or less, or 30% or less.
In this specification, the amount of a component in a vinylidene chloride resin that is assigned a renewable organic resource-derived characteristic is the sum of the values obtained by multiplying the proportion of each monomer by the amount of the component in each monomer that is assigned a renewable organic resource-derived characteristic, and dividing the product by 100.
　再生可能な有機資源由来特性の割り当ては、マスバランス方式またはブックアンドクレーム方式（ＩＳＯ　２２０９５：２０２０で定義）に基づくことが好ましく、マスバランス方式（ＩＳＯ　２２０９５：２０２０で定義）に基づくことがより好ましい。
　マスバランス方式の認証方法は、第三者機関であるＩＳＣＣ（Ｉｎｔｅｒｎａｔｉｏｎａｌ　Ｓｕｓｔａｉｎａｂｉｌｉｔｙ　ａｎｄ　Ｃａｒｂｏｎ　Ｃｅｒｔｉｆｉｃａｔｉｏｎ）のＩＳＣＣ　ＰＬＵＳ認証、ＲＳＢ（Ｔｈｅ　Ｒｏｕｎｄｔａｂｌｅ　ｏｎ　Ｓｕｓｔａｉｎａｂｌｅ　Ｂｉｏｍａｔｅｒｉａｌｓ）のＲＳＢ　Ｇｌｏｂａｌ　Ａｄｖａｎｃｅｄ　Ｐｒｏｄｕｃｔｓ認証、またはＲＥＤ（Ｒｅｎｅｗａｂｌｅ　Ｅｎｅｒｇｙ　Ｄｉｒｅｃｔｉｖｅ）のＲＥＤｃｅｒｔ２認証に基づくことが好ましい。 The allocation of renewable organic resource origin properties is preferably based on the mass balance method or the book and claim method (as defined in ISO 22095:2020), more preferably based on the mass balance method (as defined in ISO 22095:2020).
The mass balance method is preferably based on ISCC PLUS certification by the International Sustainability and Carbon Certification (ISCC), a third-party organization, RSB Global Advanced Products certification by the Roundtable on Sustainable Biomaterials (RSB), or REDcert 2 certification by the Renewable Energy Directive (RED).
　再生可能な有機資源としては、後述の塩化ビニリデン系樹脂の製造方法において記載する資源が挙げられる。 Examples of renewable organic resources include the resources described in the method for producing vinylidene chloride resin described below.
＜塩化ビニリデン系樹脂の製造方法＞
　塩化ビニリデン系樹脂の製造方法は、再生可能な有機資源由来特性を割り当てられた塩化ビニリデンおよび／または再生可能な有機資源由来特性を割り当てられた塩化ビニルを重合する工程を含む。重合方法は特に限定されず、懸濁重合法、乳化重合法、溶液重合法等の任意の重合法により合成することができる。 <Method for manufacturing vinylidene chloride resin>
The method for producing a vinylidene chloride-based resin includes the step of polymerizing vinylidene chloride that has been assigned a property derived from a renewable organic resource and/or vinyl chloride that has been assigned a property that is derived from a renewable organic resource. The polymerization method is not particularly limited, and synthesis can be performed by any polymerization method such as suspension polymerization, emulsion polymerization, and solution polymerization.
　再生可能な有機資源由来特性を割り当てられた塩化ビニリデンや塩化ビニルは、例えば、以下の方法により生成できる。
　まず、再生可能な有機資源を原料として有機化合物（炭化水素、脂肪酸、アルコール等）を生成し、マスバランス方式またはブックアンドクレーム方式に基づき、再生可能な有機資源由来特性を割り当てる。
　次に、上記有機化合物を原料として、化石資源を原料とした場合と同様の生成工程を経て塩化ビニリデンや塩化ビニルを生成する。各工程では、得られる生成物に対し、マスバランス方式またはブックアンドクレーム方式に基づき、再生可能な有機資源由来特性を順次割り当てる。 Vinylidene chloride and vinyl chloride, which are assigned characteristics derived from renewable organic resources, can be produced, for example, by the following method.
First, organic compounds (hydrocarbons, fatty acids, alcohols, etc.) are generated using renewable organic resources as raw materials, and characteristics derived from renewable organic resources are assigned based on a mass balance method or a book-and-claim method.
Next, using the organic compound as a raw material, vinylidene chloride and vinyl chloride are produced through the same production process as when fossil resources are used as a raw material. In each step, properties derived from renewable organic resources are sequentially assigned to the resulting products on a mass balance or book-and-claim basis.
　再生可能な有機資源は、バイオマスともいい、典型的には、太陽光と水と二酸化炭素とが存在すれば持続的な再生産が可能な生物資源（典型的には、光合成を行う植物）が挙げられる。したがって、採掘後の使用によって枯渇する化石資源は、ここでいう再生可能な有機資源の概念から除かれる。 Renewable organic resources, also called biomass, are typically biological resources (typically plants that perform photosynthesis) that can be reproduced sustainably in the presence of sunlight, water, and carbon dioxide. Can be mentioned. Therefore, fossil resources that are depleted through use after mining are excluded from the concept of renewable organic resources here.
　再生可能な有機資源としては、植物油およびトール油から選ばれる少なくとも１種が好ましい。
　植物油としては、例えば、菜種、大豆、油ヤシの果実、油ヤシの種子、ひまわりの種子、綿実（綿の種子）、落花生、オリーブの果実、トウモロコシの胚芽、ココナツの胚乳、胡麻、荏胡麻、亜麻仁、ひまし、米ぬか、紅花の種子、またはぶどうの種子等から搾油して得られる植物油が挙げられる。
　これらの植物油は、パルミチン酸、ステアリン酸、アラキジン酸およびベヘン酸等の飽和脂肪酸；パルミトレイン酸およびオレイン酸等の不飽和脂肪酸；リノール酸およびリノレン酸等の多価不飽和脂肪酸；等に代表される脂肪酸、ならびにこれらの脂肪酸とグリセリンとのエステル（トリグリセリド）を主成分として含むものである。天然に存在するトリグリセリドは、グリセリンと、直鎖の炭素数１０～２６のアルカン基またはアルケン基を有する脂肪酸とのエステルである。またこれらの植物油やトリグリセリドを調理等に使用した後に回収された廃植物油が挙げられる。 The renewable organic resource is preferably at least one selected from vegetable oil and tall oil.
Examples of vegetable oils include rapeseed, soybeans, oil palm fruits, oil palm seeds, sunflower seeds, cotton seeds, peanuts, olive fruits, corn germ, coconut endosperm, sesame, perilla sesame, Examples include vegetable oils obtained by pressing flaxseed, castor, rice bran, safflower seeds, grape seeds, and the like.
These vegetable oils are typified by saturated fatty acids such as palmitic acid, stearic acid, arachidic acid and behenic acid; unsaturated fatty acids such as palmitoleic acid and oleic acid; polyunsaturated fatty acids such as linoleic acid and linolenic acid; The main components are fatty acids and esters of these fatty acids and glycerin (triglycerides). Naturally occurring triglycerides are esters of glycerin and fatty acids having linear alkane or alkene groups having 10 to 26 carbon atoms. Also included are waste vegetable oils recovered after using these vegetable oils and triglycerides for cooking and the like.
　松材は松脂のような油脂成分を多く含むため、同松材を原料として蒸解等の木材パルプ加工プロセスを経てクラフトパルプを得る際に、副生物として黒液が得られる。同黒液を、酸分解して粗トール油を得て、更に同粗トール油を蒸留することでトール油（トール脂肪酸）が得られる。このようなトール脂肪酸は、オレイン酸やリノール酸等を主成分として含むものである。 Pine wood contains a large amount of oil and fat components such as pine resin, so when pine wood is used as a raw material to obtain kraft pulp through wood pulp processing processes such as cooking, black liquor is obtained as a by-product. The black liquor is decomposed with acid to obtain crude tall oil, and the crude tall oil is further distilled to obtain tall oil (tall fatty acid). Such tall fatty acids contain oleic acid, linoleic acid, etc. as main components.
　再生可能な有機資源としては、製品（ラップ、ケーシング、ラテックス、およびバインダー）のＧＨＧ排出量低減率が改善されやすい点から、植物油およびトール油から選ばれる少なくとも１種が好ましく、特に、塩化ビニリデン系樹脂のＧＨＧ排出量低減率も改善されやすい点から、廃植物油およびトール油から選ばれる少なくとも１種がより好ましい。
　再生可能な有機資源として植物油やトール油を用いた場合、大気中のＣＯ２を吸収して得られた資源であるため、製品の廃棄（焼却）までのサプライチェーン全体を範囲としたＧＨＧ排出量低減率が改善されやすい。ただし、土地の耕作等に多くのエネルギーを要する油ヤシの果実から搾油されたパーム油等を用いた場合、塩化ビニリデン系樹脂を製造するまでを範囲としたＧＨＧ排出量の低減率は逆に悪化することがある。一方、廃植物油は調理等の使用後に回収された再利用品であり、トール油はクラフトパルプを得る際の副生成物であるため、これらを用いた場合は、パーム油における問題が生じにくく、塩化ビニリデン系樹脂を製造するまでを範囲としたＧＨＧ排出量の低減率も改善されやすい。 As the renewable organic resource, at least one type selected from vegetable oil and tall oil is preferable, and vinylidene chloride-based At least one selected from waste vegetable oil and tall oil is more preferable since the GHG emission reduction rate of the resin is likely to be improved.
When vegetable oil and tall oil are used as renewable organic resources, they are obtained by absorbing CO2 from the atmosphere, so GHG emissions cover the entire supply chain up to product disposal (incineration). The reduction rate is likely to be improved. However, when palm oil extracted from oil palm fruits, which requires a lot of energy to cultivate the land, is used, the reduction rate of GHG emissions in the range up to the production of vinylidene chloride resin worsens. There are things to do. On the other hand, waste vegetable oil is a reused product recovered after use in cooking, etc., and tall oil is a by-product when obtaining kraft pulp, so when these are used, problems with palm oil are less likely to occur. The reduction rate of GHG emissions up to the production of vinylidene chloride resin is also likely to be improved.
　上述した各再生可能な有機資源は、単独で使用されてもよいし、混合して使用されてもよい。 Each of the above-mentioned renewable organic resources may be used alone or in combination.
　再生可能な有機資源がトール油や植物油である場合、再生可能な有機資源由来特性を割り当てられた塩化ビニリデンや塩化ビニルを生成する方法は、例えば、以下の通りである。
　まず、トール油や植物油を水素付加・脱酸素処理し、再生可能な有機資源由来のディーゼル（バイオディーゼル）や再生可能な有機資源由来のナフサ（バイオナフサ）を製造する。
　次に、バイオナフサと化石資源由来のナフサをクラッキング設備に投入し、エチレン等を生成する。マスバランス方式またはブックアンドクレーム方式に基づき、エチレンに再生可能な有機資源由来特性を割り当てることができる。
　さらに、エチレンから１，２－ジクロロエタン、塩化ビニル、塩化ビニリデンを従来公知の方法で順次生成する。各工程において、得られる生成物に対し、マスバランス方式またはブックアンドクレーム方式に基づき、再生可能な有機資源由来特性を割り当てることができる。 When the renewable organic resource is tall oil or vegetable oil, a method for producing vinylidene chloride or vinyl chloride that is assigned characteristics derived from the renewable organic resource is, for example, as follows.
First, tall oil and vegetable oil are hydrogenated and deoxygenated to produce diesel derived from renewable organic resources (biodiesel) and naphtha derived from renewable organic resources (bionaphtha).
Next, bio-naphtha and naphtha derived from fossil resources are fed into cracking equipment to produce ethylene, etc. Ethylene can be assigned attributes derived from renewable organic resources based on a mass balance approach or a book-and-claims approach.
Furthermore, 1,2-dichloroethane, vinyl chloride, and vinylidene chloride are sequentially produced from ethylene by a conventionally known method. At each step, the resulting product can be assigned attributes derived from renewable organic resources on a mass balance or book-and-claims basis.
＜ラップ、ケーシング、ラテックス、バインダー＞
　塩化ビニリデン系樹脂は、ラップ、ケーシング、ラテックス、バインダー等に好適に用いられる。 <Wrap, casing, latex, binder>
Vinylidene chloride resins are suitably used for wraps, casings, latex, binders, and the like.
　塩化ビニリデン系樹脂に、必要に応じて各種添加剤を配合した後、食品包装用等のラップやケーシング等に成形することができる。成形方法としては特に限定されず、例えばサーキュラーダイによるインフレーション押出成形法等の従来公知の方法が使用される。 After adding various additives to the vinylidene chloride resin as necessary, it can be molded into wraps, casings, etc. for food packaging. The molding method is not particularly limited, and conventionally known methods such as inflation extrusion using a circular die may be used.
　また、塩化ビニリデン系樹脂を乳化重合により製造し、必要に応じて各種添加剤を配合して、ラテックスを得ることができる。塩化ビニリデン系樹脂は、ガスバリア性、防湿性、ヒートシール性、保香性、耐油耐薬品性、難燃性等の特性が優れている。そのため、ラテックスはコーティング液やバインダーとして好適に用いられる。 Also, latex can be obtained by producing vinylidene chloride resin by emulsion polymerization and adding various additives as necessary. Vinylidene chloride resin has excellent properties such as gas barrier properties, moisture proofing properties, heat sealing properties, fragrance retention, oil resistance, chemical resistance, and flame retardancy. Therefore, latex is suitably used as a coating liquid or a binder.
　添加剤としては、種々の特性や成形加工性の改良を目的として添加される熱安定剤、可塑剤、加工助剤、着色剤、紫外線吸収剤、ｐＨ調整剤、分散助剤等が挙げられる。添加剤は、塩化ビニリデン系樹脂の重合工程で単量体組成物中に含有させてもよいし、上述の通り、重合工程の後に配合してもよい。 Examples of additives include heat stabilizers, plasticizers, processing aids, colorants, ultraviolet absorbers, pH adjusters, dispersion aids, etc. that are added for the purpose of improving various properties and molding processability. The additive may be incorporated into the monomer composition during the polymerization process of the vinylidene chloride resin, or may be added after the polymerization process as described above.
　以下に実施例および比較例を挙げて、本発明についてより具体的に説明するが、本発明は、本実施例に限定されるものではない。 The present invention will be described in more detail below with reference to Examples and Comparative Examples, but the present invention is not limited to these Examples.

Waste vegetable oil and/or tall oil was subjected to hydrogenation and deoxygenation treatment to prepare naphtha derived from renewable organic resources (bio-naphtha).
The prepared bio-naphtha and fossil-derived naphtha were fed into a cracking facility to produce ethylene.
