Description
本発明は、耐熱性および色調に優れた脂環族成分含有ポリエステル樹脂組成物の製造方法に関するものである。さらに詳しくは、特定のリン化合物を添加した後に、脂環族ジオールを添加することで、脂環族ジオールの分解を抑制し、耐熱性および色調に優れた脂環族成分を含有するポリエステル樹脂組成物を経済的に有意な方法で製造する方法に関する。 The present invention relates to a method for producing an alicyclic component-containing polyester resin composition excellent in heat resistance and color tone. More specifically, a polyester resin composition containing an alicyclic component excellent in heat resistance and color tone is suppressed by adding an alicyclic diol after adding a specific phosphorus compound, thereby suppressing decomposition of the alicyclic diol. The present invention relates to a method for manufacturing an object in an economically significant way.
脂環族成分を含有するポリエステルは、ポリエチレンテレフタレート（以下ＰＥＴ）などの芳香族ポリエステルとは異なった光学特性、結晶化特性、機械特性を有しており、該ポリエステル単独で、または芳香族ポリエステルと組み合わせて使用される。 Polyester containing an alicyclic component has optical properties, crystallization properties, and mechanical properties different from those of aromatic polyesters such as polyethylene terephthalate (hereinafter referred to as PET). Used in combination.
工業的な利用としてはたとえば、屈折率の異なるポリマーを交互に積層したフィルムは、特定の波長の光を効率良く反射させることができるため、光フィルターや反射体として利用されている。また光学等方性に優れたフィルムは、液晶ディスプレイ等において位相差フィルムなどとして利用されている。 As an industrial application, for example, a film in which polymers having different refractive indexes are alternately laminated can efficiently reflect light having a specific wavelength, and thus is used as an optical filter or a reflector. A film excellent in optical isotropy is used as a retardation film or the like in a liquid crystal display or the like.
しかしながら、脂環族成分のひとつである脂環族ジオールは、酸や水分に晒されると分解するため、ジカルボン酸とジオールを出発物質とする直接エステル化法で得られた脂環族成分含有ポリエステルは、ジカルボン酸ジエステルとジオールとを出発物質とするエステル交換法によって得られた脂環族成分含有ポリエステルと比較して、耐熱性が劣るという問題があった。直接エステル化法は、エステル交換法と比較して原料が安価であり、経済的に優位な方法であるため、脂環族成分を含有するポリエステルにおいても、エステル化法による製造方法の確立が切望されていた。 However, alicyclic diols, which are one of the alicyclic components, decompose when exposed to acids and moisture, so alicyclic component-containing polyesters obtained by direct esterification using dicarboxylic acid and diol as starting materials. Has a problem that the heat resistance is inferior to that of an alicyclic component-containing polyester obtained by a transesterification method using a dicarboxylic acid diester and a diol as starting materials. The direct esterification method is an economically advantageous method because the raw materials are cheaper than the transesterification method, and therefore it is eager to establish a production method by an esterification method even for polyesters containing alicyclic components. It had been.
これに対し、特許文献１および２では、ジカルボン酸およびジオールのエステル化反応、重縮合反応によって特定値以下の酸価のエステルを得たのちに、脂環族ジオールを添加し、重縮合する方法が開示されている。しかし、酸価を特定値まで低下させるにはエステル化反応、重縮合反応に長時間を有するため、得られるポリエステル樹脂の耐熱性および色調が十分でなかった。

本発明のポリエステル樹脂組成物の製造方法は、少なくとも脂環族ジカルボン酸成分および脂環族ジオール成分な下記式（１）、（２）を満足するポリエステルを製造するに際して、ジカルボン酸と脂肪族ジオールのエステル化反応から得られた酸価が１００〜５００μ当量／ｇのエステル低重合体中に、３価のリン化合物、次いで脂環族ジオールを添加し、エステル化反応、引き続き重縮合触媒の存在下で重縮合反応を行うことを特徴とするポリエステル樹脂組成物の製造方法である。 The method for producing a polyester resin composition of the present invention comprises producing a polyester satisfying the following formulas (1) and (2) which are at least an alicyclic dicarboxylic acid component and an alicyclic diol component. A trivalent phosphorus compound and then an alicyclic diol are added to an ester low polymer having an acid value of 100 to 500 µequivalent / g obtained from the esterification reaction of the esterification reaction, followed by the presence of a polycondensation catalyst.

本発明の製造方法によって得られるポリエステル樹脂組成物は、ガラス転移点温度（以下Ｔｇ）が６５℃から８６℃の範囲にあることが必要である。
65 ° C. ≦ Glass transition temperature by differential scanning calorimetry ≦ 86 ° C. (1)
1.500 ≦ refractive index at sodium D line ≦ 1.570 (2)
The polyester resin composition obtained by the production method of the present invention needs to have a glass transition temperature (hereinafter referred to as Tg) in the range of 65 ° C to 86 ° C.
Ｔｇが６５℃未満の場合、耐熱性が不足するために光学特性が経時変化しやすく、またＰＥＴ等と積層製膜する際には積層樹脂間のＴｇ差が大きくなるために積層ムラ等発生し、製膜安定性が損なわれる。積層フィルムとする場合、本発明のポリエステル樹脂組成物のＴｇを積層ポリマーのＴｇと合致させることが好ましく、積層ポリマーのＴｇ（Ｔｇ１）と本発明のポリエステル樹脂のＴｇ（Ｔｇ２）の差（｜Ｔｇ１−Ｔｇ２｜）が１０℃以内、さらには５℃以内であることが好ましい。 When Tg is less than 65 ° C, the optical characteristics are likely to change with time due to insufficient heat resistance, and when the film is laminated with PET or the like, the Tg difference between the laminated resins becomes large, resulting in lamination unevenness. , Film formation stability is impaired. In the case of a laminated film, it is preferable to match the Tg of the polyester resin composition of the present invention with the Tg of the laminated polymer, and the difference between the Tg (Tg1) of the laminated polymer and the Tg (Tg2) of the polyester resin of the present invention (| Tg1 -Tg2 |) is preferably within 10 ° C, more preferably within 5 ° C.
Ｔｇが９０℃を超える場合には、ＰＥＴ等を積層する際にＴｇ差が大きくなりすぎるために、上記同様、積層ムラ等発生し、製膜安定性が損なわれ、またポリエステル樹脂組成物の屈折率を低くすることが困難になってくる。よって本発明のポリエステル樹脂組成物のＴｇは、７０〜８６℃の範囲が好ましく、さらには７５〜８５℃の範囲が好ましい。 When the Tg exceeds 90 ° C., the Tg difference becomes too large when laminating PET and the like, and as described above, laminating unevenness and the like occur, film formation stability is impaired, and the refraction of the polyester resin composition It becomes difficult to lower the rate. Therefore, Tg of the polyester resin composition of the present invention is preferably in the range of 70 to 86 ° C, more preferably in the range of 75 to 85 ° C.
本発明の製造方法によって得られるポリエステル樹脂組成物の屈折率については，
１．５００〜１．５７０の範囲にある必要がある。１．５００未満とすることはポリエステル樹脂では困難であり、１．５７０を超える場合には、積層ポリマーとの屈折率差が小さくなるため、得られた積層フィルムの光反射性が小さくなる。なお、本発明における屈折率は、２３℃の条件にてナトリウムＤ線を用いて測定した屈折率を指し、１．５１０〜１．５６０の範囲であることが好ましい。
Regarding the refractive index of the polyester resin composition obtained by the production method of the present invention,
It needs to be in the range of 1.500 to 1.570. It is difficult for the polyester resin to be less than 1.500, and when it exceeds 1.570, the difference in refractive index from the laminated polymer becomes small, so the light reflectivity of the obtained laminated film becomes small. In addition, the refractive index in this invention points out the refractive index measured using the sodium D line | wire on the conditions of 23 degreeC, and it is preferable that it is the range of 1.510-1.560.
前記した特性を与えるためには、ポリエステル樹脂組成物は少なくとも脂環族ジカルボン酸成分および脂環族ジオール成分を含むことが必要である。ポリエステル樹脂組成物に含まれる芳香環はＴｇを高める効果があるが、同時に屈折率を高め、光弾性係数を高める効果がある。光弾性係数が大きい場合、フィルムに応力が作用した際に位相差が大きく変化するため、液晶ディスプレイ用途のフィルムには不適当である。 In order to give the above-described properties, the polyester resin composition needs to contain at least an alicyclic dicarboxylic acid component and an alicyclic diol component. The aromatic ring contained in the polyester resin composition has the effect of increasing Tg, but at the same time has the effect of increasing the refractive index and increasing the photoelastic coefficient. When the photoelastic coefficient is large, the phase difference changes greatly when a stress is applied to the film, so that it is not suitable for a film for use in a liquid crystal display.
そこで、本発明のポリエステル樹脂組成物は、この芳香環成分を脂環族ジカルボン酸成分や脂環族ジオールで置換することにより、屈折率や光弾性係数を低減させている。本発明における脂環族ジカルボン酸成分としては、シクロヘキサンジカルボン酸成分やデカリンジカルボン酸成分等を挙げることができる。特に入手の容易性や重合反応性の観点からはシクロヘキサンジカルボン酸成分が好ましい。シクロヘキサンジカルボン酸成分は、シクロヘキサンジカルボン酸やそのエステルを原料として用いることができる。 Therefore, in the polyester resin composition of the present invention, the refractive index and the photoelastic coefficient are reduced by substituting this aromatic ring component with an alicyclic dicarboxylic acid component or an alicyclic diol. Examples of the alicyclic dicarboxylic acid component in the present invention include a cyclohexane dicarboxylic acid component and a decalin dicarboxylic acid component. In particular, a cyclohexanedicarboxylic acid component is preferable from the viewpoint of availability and polymerization reactivity. As the cyclohexanedicarboxylic acid component, cyclohexanedicarboxylic acid or an ester thereof can be used as a raw material.
なお、シクロヘキサンジカルボン酸成分など脂環族成分には立体異性体として、シス体、トランス体が存在するが、本発明ではトランス体比率が４０％以下であることが好ましい。トランス体比率が高いと光弾性係数が大きくなるため劣る傾向にある。また、トランス体は、シス体に比べ、融点が高いため、トランス体比率が高くなると、室温程度で保管、または、輸送中等に、容易に凝固し、沈降してしまい、不均一となり反応性が悪くなるだけでなく、取り扱い上においても作業性が悪くなる。よって、トランス体比率は、好ましくは、３５％以下、より好ましくは、３０％以下である。 The alicyclic component such as the cyclohexanedicarboxylic acid component includes a cis isomer and a trans isomer as stereoisomers. In the present invention, the trans isomer ratio is preferably 40% or less. If the ratio of the transformer body is high, the photoelastic coefficient tends to be large, so that it tends to be poor. In addition, since the trans isomer has a higher melting point than the cis isomer, if the trans isomer ratio is high, it easily coagulates and settles during storage at room temperature or during transportation, resulting in heterogeneity and reactivity. Not only is it worse, but workability is also worse in handling. Therefore, the trans isomer ratio is preferably 35% or less, and more preferably 30% or less.
本発明における脂環族ジオールとしては、スピログリコール成分やイソソルビド成分が好ましく、特に得られるポリエステルの色調の観点からスピログリコール成分が好ましい。ここでスピログリコールとは３，９−ビス（２−ヒドロキシ−１，１−ジメチルエチル）−２，４，８，１０−テトラオキサスピロ［５，５］ウンデカンを指す。 As an alicyclic diol in this invention, a spiroglycol component and an isosorbide component are preferable, and a spiroglycol component is preferable from a viewpoint of the color tone of the polyester obtained especially. Here, spiroglycol refers to 3,9-bis (2-hydroxy-1,1-dimethylethyl) -2,4,8,10-tetraoxaspiro [5,5] undecane.
本発明において、例えばＰＥＴの場合、テレフタル酸成分（芳香環成分）をシクロヘキサンジカルボン酸等で置換するとＴｇが低下する。そこでスピログリコール成分やイソソルビド成分など脂環族ジオール成分をエチレングリコール成分に置換することでＴｇが上昇し、結果として本発明の積層するＰＥＴと同程度のＴｇに調整することができる。Ｔｇを上昇させる効果はスピログリコール成分やイソソルビド成分において顕著である。 In the present invention, for example, in the case of PET, Tg decreases when the terephthalic acid component (aromatic ring component) is substituted with cyclohexanedicarboxylic acid or the like. Then, Tg rises by substituting alicyclic diol components, such as a spiroglycol component and an isosorbide component, with an ethylene glycol component, and as a result, it can adjust to Tg comparable to PET which laminates | stacks this invention. The effect of increasing Tg is significant in spiroglycol components and isosorbide components.
本発明のポリエステル樹脂組成物は、屈折率や光弾性係数を低下させるために、ポリエステル樹脂組成物１ｋｇ中に含有される芳香環モル数を４．８モル以下とすることが好ましい。４．８モルを超える場合には屈折率や光弾性係数が増大する傾向にあるため好ましくない。なお、本発明における芳香環モル数とはベンゼン環モル数を基本単位としている。本発明における定義をＰＥＴとポリエチレンナフタレート（以下、ＰＥＮ）を例にして説明する。 In the polyester resin composition of the present invention, the number of moles of aromatic rings contained in 1 kg of the polyester resin composition is preferably 4.8 mol or less in order to reduce the refractive index and the photoelastic coefficient. When it exceeds 4.8 mol, the refractive index and the photoelastic coefficient tend to increase, which is not preferable. The number of moles of aromatic rings in the present invention is based on the number of moles of benzene rings. The definition in the present invention will be described using PET and polyethylene naphthalate (hereinafter, PEN) as examples.
ＰＥＴの場合、基本繰り返し単位の分子量は１９２であるため、ポリマー１ｋｇ当たりの基本繰り返し単位数は５．２となる。基本繰り返し単位中にテレフタル酸成分（ベンゼン環１個相当）は１モル含まれるため、ＰＥＴの芳香環モル数は５．２と計算される。一方、ＰＥＮの場合、基本繰り返し単位の分子量は２４２であり、ポリマー１ｋｇ当たりの基本繰り返し単位数は４．１である。基本繰り返し単位中にナフタレンジカルボン酸成分は１モル含まれるが、ナフタレン環はベンゼン環２個に相当するため、ＰＥＮの芳香環モル数は８．２モルと計算する。 In the case of PET, since the molecular weight of the basic repeating unit is 192, the number of basic repeating units per kg of the polymer is 5.2. Since 1 mol of the terephthalic acid component (corresponding to one benzene ring) is contained in the basic repeating unit, the number of moles of aromatic ring of PET is calculated to be 5.2. On the other hand, in the case of PEN, the molecular weight of the basic repeating unit is 242 and the number of basic repeating units per kg of the polymer is 4.1. Although 1 mole of naphthalene dicarboxylic acid component is contained in the basic repeating unit, since the naphthalene ring corresponds to 2 benzene rings, the number of moles of aromatic ring of PEN is calculated as 8.2 moles.
本発明のポリエステル樹脂組成物は、少なくとも脂環族ジカルボン酸成分および脂環族ジオール成分を含むが、その他ジカルボン酸成分としては、２，６−ナフタレンジカルボン酸成分、テレフタル酸成分、イソフタル酸成分から選択される少なくとも一種のジカルボン酸成分を全ジカルボン酸成分に対して２０〜９５モル％含有することが好ましい。また脂肪族ジオール成分については、エチレングリコール成分をジオール成分として２０〜９５モル％含有することが好ましい。前記した芳香族ジカルボン酸成分が２０モル％未満の場合、Ｔｇを６５℃以上にすることが難しくなり、例えばＰＥＴやＰＥＮと積層する際にはこれらの樹脂との層間接着性が悪化してくる。同様にエチレングリコール成分が２０モル％未満の場合、ＰＥＴやＰＥＮと積層した際、これらの樹脂との層間接着性が悪化してくる。一方、芳香族ジカルボン酸成分が９５モル％を超える場合、屈折率や光弾性係数を低減することが難しくなり、エチレングリコール成分が９５モル％を超える場合にはＴｇを６５℃以上にすることが難しくなる。 The polyester resin composition of the present invention contains at least an alicyclic dicarboxylic acid component and an alicyclic diol component, and other dicarboxylic acid components include 2,6-naphthalenedicarboxylic acid component, terephthalic acid component, and isophthalic acid component. It is preferable to contain at least one selected dicarboxylic acid component in an amount of 20 to 95 mol% based on the total dicarboxylic acid component. Moreover, about an aliphatic diol component, it is preferable to contain 20-95 mol% of ethylene glycol components as a diol component. When the above-mentioned aromatic dicarboxylic acid component is less than 20 mol%, it becomes difficult to make the Tg 65 ° C. or more, and for example, when laminating with PET or PEN, the interlayer adhesion with these resins deteriorates. . Similarly, when the ethylene glycol component is less than 20 mol%, interlayer adhesion with these resins deteriorates when laminated with PET or PEN. On the other hand, when the aromatic dicarboxylic acid component exceeds 95 mol%, it is difficult to reduce the refractive index and the photoelastic coefficient. When the ethylene glycol component exceeds 95 mol%, the Tg may be 65 ° C. or higher. It becomes difficult.
本発明のポリエステル樹脂組成物において、脂環族ジカルボン酸成分、脂環族ジオールの含有量は、前記記載よりそれぞれ５〜８０モル％の範囲が好ましく、さらに８〜５０モル％が好ましい。 In the polyester resin composition of the present invention, the content of the alicyclic dicarboxylic acid component and the alicyclic diol is preferably in the range of 5 to 80 mol%, more preferably 8 to 50 mol% from the above description.
本発明のポリエステル樹脂組成物に含有される芳香族ジカルボン酸成分は、前記した種類から少なくとも選択されるが、屈折率や光弾性係数の観点からテレフタル酸成分やイソフタル酸成分が好ましく、これらは同時に使用してもかまわない。特にテレフタル酸成分はその他ポリエステル樹脂組成物との接着性等の観点から主に使用することが好ましい。その他ジカルボン酸成分としては、特性の許す限り従来公知のものを共重合しても構わなく、グリコール成分についても同様である。このような成分としては、例えばアジピン酸、セバシン酸等の脂肪族ジカルボン酸やそのエステル、４，４’−ビスフェニレンジカルボン酸、５−ソジウムスルホイソフタル酸、ジフェン酸等の芳香族ジカルボン酸やそのエステル、ジエチレングリコール、ブタンジオール、プロパンジオール、ポリエチレングリコール、ポリテトラメチレングリコール等のグリコール成分を挙げることができる。 The aromatic dicarboxylic acid component contained in the polyester resin composition of the present invention is at least selected from the types described above, but from the viewpoint of refractive index and photoelastic coefficient, a terephthalic acid component and an isophthalic acid component are preferable, and these are simultaneously You can use it. In particular, the terephthalic acid component is preferably used mainly from the viewpoint of adhesion to other polyester resin compositions. As the other dicarboxylic acid component, a conventionally known component may be copolymerized as long as the characteristics allow, and the same applies to the glycol component. Examples of such components include aliphatic dicarboxylic acids such as adipic acid and sebacic acid and esters thereof, aromatic dicarboxylic acids such as 4,4′-bisphenylenedicarboxylic acid, 5-sodiumsulfoisophthalic acid, diphenic acid, and the like. Examples thereof include glycol components such as esters, diethylene glycol, butanediol, propanediol, polyethylene glycol, and polytetramethylene glycol.
本発明のポリエステル樹脂組成物の製造方法におけるジカルボン酸と脂肪族ジオールのエステル化反応は、従来のジカルボン酸とジオールを原料とするポリエステル樹脂の製造方法におけるエステル化反応条件を採用することができる。例えば、原料ジカルボン酸に対するジオールの仕込み比（モル比）を１．０１〜１０として反応缶に仕込む。モル比は、ジオールの脱水反応などの副反応を抑制する点で、１．１〜５．０が好ましく、さらに好ましくは１．１５〜２である。エステル化反応の温度は特に限定されないが、１００〜２７０℃、より好ましくは１２０〜２６０℃、更に好ましくは１５０〜２５０℃である。エステル化反応の圧力は特に限定されないが５０ｋＰａ〜３００ｋＰａが好ましい。エステル化反応は、得られる樹脂組成物の透明性、熱安定性、色調の面から無触媒で行うことが好ましいが、触媒を用いても良い。 The esterification reaction of a dicarboxylic acid and an aliphatic diol in the method for producing a polyester resin composition of the present invention can employ the esterification reaction conditions in a conventional method for producing a polyester resin using a dicarboxylic acid and a diol as raw materials. For example, the charging ratio (molar ratio) of the diol to the raw material dicarboxylic acid is set to 1.01 to 10 and charged into the reaction can. The molar ratio is preferably 1.1 to 5.0, more preferably 1.15 to 2, in terms of suppressing side reactions such as dehydration reaction of diol. Although the temperature of esterification reaction is not specifically limited, It is 100-270 degreeC, More preferably, it is 120-260 degreeC, More preferably, it is 150-250 degreeC. The pressure for the esterification reaction is not particularly limited, but is preferably 50 kPa to 300 kPa. The esterification reaction is preferably performed without a catalyst from the viewpoint of the transparency, thermal stability, and color tone of the resin composition to be obtained, but a catalyst may be used.
本発明のポリエステル樹脂組成物の製造方法では、ジカルボン酸と脂肪族ジオールのエステル化反応によって得られた酸価が２１０〜３５０μ当量／ｇであるエステル低重合体中に、３価のリン化合物、次いで脂環族ジオールを添加する必要がある。 In the method for producing a polyester resin composition of the present invention, a trivalent phosphorus compound is contained in an ester low polymer having an acid value of 210 to 350 μeq / g obtained by an esterification reaction of a dicarboxylic acid and an aliphatic diol. Then, it is necessary to add an alicyclic diol.
エステル低重合体の酸価が１００μ当量／ｇ未満の場合は、エステル化工程に長時間を要するため、得られるポリエステル樹脂組成物が着色する。５００μ当量／ｇを超える場合は次に添加する脂環属ジオールが酸によって分解され、得られるポリエステル樹脂の耐熱性が低下する。得られるポリエステル樹脂組成物の耐熱性と色調の点から、好ましくは２００〜３００μ当量／ｇである。 When the acid value of the ester low polymer is less than 100 μequivalent / g, the esterification process takes a long time, and the resulting polyester resin composition is colored. When it exceeds 500 μeq / g, the alicyclic diol to be added next is decomposed by an acid, and the heat resistance of the resulting polyester resin is lowered. From the viewpoint of heat resistance and color tone of the polyester resin composition obtained, good Mashiku is 200~300μ eq / g.

本発明の製造方法では、３価のリン化合物は、脂環族ジオールを添加する前までに反応系に添加する必要がある。３価のリン化合物によって、酸による脂環族ジオールの分解を抑制し、得られるポリエステル組成物の耐熱性を向上することができる。 In the production method of the present invention, it is necessary to add the trivalent phosphorus compound to the reaction system before adding the alicyclic diol. By the trivalent phosphorus compound, the decomposition of the alicyclic diol by the acid can be suppressed, and the heat resistance of the resulting polyester composition can be improved.
３価のリン化合物の添加量は、特に限定されないが、リン元素として７０〜３００ｐｐｍが好ましい。３価のリン化合物をリン元素として７０〜３００ｐｐｍ添加することで、酸による脂環族ジオールの分解を抑制することができ、得られるポリエステル樹脂組成物の耐熱性、色調が向上する。３価のリン化合物の添加量がリン元素として７０ｐｐｍ未満の場合、脂環族ジオールの分解抑制が不十分で、得られるポリエステル樹脂組成物の熱安定性が不足し、色調が悪化する場合がある。一方、３価のリン化合物の添加量が、リン元素として３００ｐｐｍを超えると、重縮合反応の進行が遅延する場合がある。 Although the addition amount of a trivalent phosphorus compound is not specifically limited, 70-300 ppm is preferable as a phosphorus element. By adding 70 to 300 ppm of a trivalent phosphorus compound as a phosphorus element, decomposition of the alicyclic diol by an acid can be suppressed, and the heat resistance and color tone of the resulting polyester resin composition are improved. When the addition amount of the trivalent phosphorus compound is less than 70 ppm as the phosphorus element, the decomposition suppression of the alicyclic diol is insufficient, the thermal stability of the resulting polyester resin composition is insufficient, and the color tone may deteriorate. . On the other hand, when the addition amount of the trivalent phosphorus compound exceeds 300 ppm as the phosphorus element, the progress of the polycondensation reaction may be delayed.
脂環族ジオールを添加する際の温度は特に限定されないが、脂環族ジオールの分解抑制の点から２６０℃以下で添加することが好ましく、特に好ましくは２４０℃以下である。 Although the temperature at the time of adding alicyclic diol is not specifically limited, It is preferable to add at 260 degrees C or less from the point of the decomposition | disassembly suppression of alicyclic diol, Especially preferably, it is 240 degrees C or less.
本発明の製造方法では、式（３）に示される５価のリン化合物をジカルボン酸と脂肪族ジオールのエステル化反応開始から重縮合反応終了までの任意の段階で添加することが得られるポリエステル樹脂組成物の熱安定性の点から好ましい。 In the production method of the present invention, a polyester resin obtained by adding the pentavalent phosphorus compound represented by formula (3) at any stage from the start of esterification reaction of dicarboxylic acid and aliphatic diol to the end of polycondensation reaction. It is preferable from the viewpoint of the thermal stability of the composition.

It is preferable to do. When the addition amount of the pentavalent phosphorus compound is less than 5 ppm in terms of phosphorus element, the heat resistance of the polyester resin composition may be inferior. On the other hand, when the content of the pentavalent phosphorus compound exceeds 150 ppm in terms of phosphorus element, the progress of the polycondensation reaction may be delayed.

Although the addition amount of a polycondensation catalyst is not specifically limited, For example, in the case of a titanium compound, it is preferable to add 0.5-50 ppm as a titanium element. If it exceeds 50 ppm, the amount of metal to be contained increases, so that the heat resistance may decrease or the color tone b value may increase. Moreover, when it is less than 0.5 ppm, the polymerization activity may not be sufficient.

本発明の製造方法において、重縮合触媒の添加時期は、重合反応器内の減圧を始める前に反応系へ添加させればよく、特に限定されないが、エステル低重合体と脂環族ジオールのエステル化反応においては、チタン触媒は存在させない方が好ましい。エステル低重合体と脂環族ジオールのエステル化反応終了前にチタン触媒を添加した場合、チタン触媒に起因した微細粒子が発生し、得られたポリエステル樹脂に濁りが発生する場合がある。 In the production method of the present invention, the addition timing of the polycondensation catalyst may be added to the reaction system before starting the pressure reduction in the polymerization reactor, and is not particularly limited. However, the ester of the ester low polymer and the alicyclic diol is not limited. In the conversion reaction, it is preferable that no titanium catalyst is present. When the titanium catalyst is added before the esterification reaction of the ester low polymer and the alicyclic diol is completed, fine particles resulting from the titanium catalyst may be generated, and turbidity may be generated in the obtained polyester resin.
本発明のポリエステル樹脂組成物の製造方法としては、ポリエステル樹脂組成物のゲル化抑制の観点から重縮合温度を２６０〜２８０℃の出来るだけ低温で実施することが好ましい。重縮合温度とは、通常、２３０〜２４０℃から徐々に温度を上げていき、ある目標の温度に到達した後は一定の温度で重縮合するため、その最終の一定温度のことである。２８０℃より高い場合は、重合は促進されるものの、同様に高温下でゲル化も促進され、また、２６０℃より低い場合は、重合活性が落ち、重合時間が遅延することで同様にゲル化が促進されるため好ましくない。従って、重縮合温度は、好ましくは、２６５〜２７５℃、より好ましくは２６８〜２７２℃である。 As a manufacturing method of the polyester resin composition of this invention, it is preferable to implement polycondensation temperature at the lowest possible temperature of 260-280 degreeC from a viewpoint of gelatinization suppression of a polyester resin composition. The polycondensation temperature is usually the final constant temperature because the temperature is gradually raised from 230 to 240 ° C., and after reaching a certain target temperature, polycondensation is performed at a constant temperature. When the temperature is higher than 280 ° C, the polymerization is promoted, but also gelation is promoted at a high temperature. When the temperature is lower than 260 ° C, the polymerization activity is lowered, and the polymerization time is delayed, so that the gelation is similarly performed. Is not preferable because it is promoted. Therefore, the polycondensation temperature is preferably 265 to 275 ° C, more preferably 268 to 272 ° C.
本発明のポリエステル樹脂組成物は、固有粘度が０．６５〜１．０の範囲であることが好ましい。固有粘度が０．６５未満の場合、ポリエステル樹脂組成物が脆くなるために好ましくなく、固有粘度が１．０を超える場合にはその溶融粘度が高くなるため、精度の良い積層フィルムを得ることが困難になる。 The polyester resin composition of the present invention preferably has an intrinsic viscosity in the range of 0.65 to 1.0. When the intrinsic viscosity is less than 0.65, the polyester resin composition is not preferable because it becomes brittle. When the intrinsic viscosity exceeds 1.0, the melt viscosity becomes high, so that a highly accurate laminated film can be obtained. It becomes difficult.
次に、本発明のポリエステル樹脂組成物の製造方法について詳しく説明する。 Next, the manufacturing method of the polyester resin composition of this invention is demonstrated in detail.
テレフタル酸、シクロヘキサンジカルボン酸とエチレングリコールとを反応装置へ仕込み、常圧下温度を２５０℃付近までゆっくり昇温しながら水を留出させ、得られるエステル低重合体の酸価が１００〜５００μ当量／ｇとなるまで水を反応系外へ留出させながらエステル化反応を進行させる。 Terephthalic acid, cyclohexanedicarboxylic acid and ethylene glycol are charged into a reactor, and water is distilled while slowly raising the temperature under normal pressure to around 250 ° C., and the acid value of the resulting ester low polymer is 100 to 500 μequivalent / The esterification reaction is allowed to proceed while distilling water out of the reaction system until it reaches g.
得られた酸価が１００〜５００μ当量／ｇのエステル低重合体に、ビス（２，６−ジ−ｔｅｒｔ−ブチル−４−メチルフェニル）ペンタエリスリトール−ジ−ホスファイト、エチルジエチルホスホノアセテート、水酸化カリウムを添加し、次いでスピログリコールを添加する。スピログリコールとエステル低重合体とのエステル化反応を実施し、所定量の水が留出した後、重縮合反応缶へ投入する。さらに、重縮合触媒としてチタン化合物を添加する。重縮合反応は、装置内温度をゆっくり２８０℃まで昇温しながら装置内圧力を常圧から１３３Ｐａ以下まで減圧する。重合反応の進行に従って反応物の粘度が上昇する。反応物の攪拌トルクが重合終了目標となったら缶内の圧力を常圧に復帰し、ポリエステル樹脂組成物を得る。 The resulting ester low polymer having an acid value of 100 to 500 μeq / g was added to bis (2,6-di-tert-butyl-4-methylphenyl) pentaerythritol-di-phosphite, ethyl diethylphosphonoacetate, Potassium hydroxide is added followed by spiroglycol. An esterification reaction between spiroglycol and a low ester polymer is carried out, and after a predetermined amount of water is distilled off, it is put into a polycondensation reaction can. Further, a titanium compound is added as a polycondensation catalyst. In the polycondensation reaction, the internal pressure of the apparatus is reduced from normal pressure to 133 Pa or lower while the internal temperature is slowly raised to 280 ° C. As the polymerization reaction proceeds, the viscosity of the reaction product increases. When the stirring torque of the reaction product becomes the target for completion of polymerization, the pressure in the can is returned to normal pressure to obtain a polyester resin composition.
このようにしてポリエステル樹脂組成物を得ることができるが、上記は一例であって、ジカルボン酸、ジオールや触媒および重合条件はこれに限定されるわけではない。 In this way, a polyester resin composition can be obtained, but the above is an example, and the dicarboxylic acid, diol, catalyst, and polymerization conditions are not limited thereto.
このようにして得られたポリエステル樹脂組成物は、光弾性係数が低く、液晶ディスプレイとして好適である。また、ＰＥＴ等を交互に積層したフィルムは光反射性に優れ、反射材用途に好適である。 The polyester resin composition thus obtained has a low photoelastic coefficient and is suitable as a liquid crystal display. Moreover, the film which laminated | stacked PET etc. alternately is excellent in light reflectivity, and is suitable for a reflector use.

In the polymerization of the polyester resin of Example 1, 25 mol of the cyclohexanedicarboxylic acid component was copolymerized and the polyester was polymerized in the same manner except that the spiroglycol was not copolymerized to obtain a laminated film. Although a result is shown to Tables 1-3, although a refractive index is in a target range, Tg fell, it was inferior to the peelability of a laminated | multilayer film, and the reflectance was also small. Further, during the polycondensation, many low molecular weight droplets were splashed and the vacuum circuit was slightly blocked, resulting in poor vacuum.
