Description

本発明は、パーフルオロビニルエーテルモノマに関し、さらに詳しくは、嵩高い置換基を有するパーフルオロビニルエーテルモノマに関する。   The present invention relates to a perfluorovinyl ether monomer, and more particularly to a perfluorovinyl ether monomer having a bulky substituent.

フッ素系ポリマは、一般にテトラフルオロエチレン(TFE)と、ビニル基を有するモノマとの共重合で得られている。フッ素系ポリマは、原料として用いられるビニルモノマの種類や分子構造に応じて、耐熱性、耐薬品性、電気絶縁性、プロトン伝導性などの様々な優れた特性を示す。このようなフッ素系ポリマの製造方法に関し、従来から種々の提案がなされている。   The fluorine-based polymer is generally obtained by copolymerization of tetrafluoroethylene (TFE) and a monomer having a vinyl group. Fluoropolymers exhibit various excellent properties such as heat resistance, chemical resistance, electrical insulation, and proton conductivity depending on the type and molecular structure of the vinyl monomer used as a raw material. Various proposals have hitherto been made regarding methods for producing such fluorine-based polymers.

例えば、特許文献1には、テトラフルオロエチレン(TFE)と、パーフルオロイソブチルビニルエーテル(PIBVE)とを共重合させることにより得られる含フッ素共重合体が開示されている。
同文献には、末端に分岐構造(−OCF2CF(CF3)2)を有するモノマを用いた共重合体は、末端に分岐構造を備えていないモノマを用いた共重合体に比べて、成形性及び高温特性が高くなる点が記載されている。
For example, Patent Document 1 discloses a fluorine-containing copolymer obtained by copolymerizing tetrafluoroethylene (TFE) and perfluoroisobutyl vinyl ether (PIBVE).
In this document, a copolymer using a monomer having a branched structure (—OCF 2 CF (CF 3 ) 2 ) at the terminal is compared with a copolymer using a monomer having no terminal branched structure. The point that a moldability and a high temperature characteristic become high is described.

非特許文献1には、パーフルオロt−ブチルビニルエーテルモノマの合成、及び、このモノマとTFEとの共重合が開示されている。
同文献には、
(a)パーフルオロt−ブチルビニルエーテルモノマが嵩高いため、ホモポリマは得られなかった点、及び、
(b)このビニルエーテルモノマとTFEとの共重合は進行したが、共重合体が溶媒に溶けなかったため、解析ができなかった点
が記載されている。
Non-Patent Document 1 discloses synthesis of perfluoro t-butyl vinyl ether monomer and copolymerization of this monomer and TFE.
In the same document,
(A) Since perfluoro t-butyl vinyl ether monomer is bulky, no homopolymer was obtained, and
(B) Although the copolymerization of this vinyl ether monomer and TFE has progressed, it is described that the copolymer could not be analyzed because it was not soluble in the solvent.

非特許文献2には、ヘキサフルオロプロペンオキシド(HFPO)と各種アルコールとの反応が記載されている。
同文献には、アルコールとして1級、2級アルコールを用いた場合には、HFPOに対してアルコールが2分子求核攻撃した化合物が得られる点が記載されている。
Non-Patent Document 2 describes reactions between hexafluoropropene oxide (HFPO) and various alcohols.
This document describes that when a primary or secondary alcohol is used as the alcohol, a compound obtained by nucleophilic attack of two molecules of alcohol against HFPO is obtained.

フッ素系ポリマを合成する場合において、多分岐構造を有するビニルモノマーを原料に用いると、嵩高いポリマ(すなわち、ガス透過性に優れたポリマ)が得られる可能性がある。しかしながら、ビニル基を有するモノマーの合成法は限られている。多くは、HFPOを用いた合成法である。しかしながら、この方法で得られるモノマーの分岐部は、−C(Rf)2Fとなり、C−F結合が残る。 When synthesizing a fluorine-based polymer, if a vinyl monomer having a multi-branched structure is used as a raw material, a bulky polymer (that is, a polymer having excellent gas permeability) may be obtained. However, methods for synthesizing monomers having a vinyl group are limited. Many are synthetic methods using HFPO. However, the branched portion of the monomer obtained by this method becomes —C (Rf) 2 F, and the C—F bond remains.

また、嵩高いフッ素系ポリマを得るために、原料としてパーフルオロ−2,2−ジメチル−1,3−ジオキソール(PDD)を用いることも考えられる。しかしながら、PDDは、合成ステップ数が多い上に収率が低いため、得られるポリマのコストが高くなるという問題があった。   In order to obtain a bulky fluorine polymer, it is also conceivable to use perfluoro-2,2-dimethyl-1,3-dioxole (PDD) as a raw material. However, PDD has a problem in that the number of synthesis steps is large and the yield is low, so that the cost of the obtained polymer becomes high.

本発明が解決しようとする課題は、多分岐構造を備えた新規なパーフルオロビニルエーテルモノマを提供することにある。
また、本発明が解決しようとする他の課題は、合成が容易で、かつ、低コストなパーフルオロビニルエーテルモノマを提供することにある。

Another object of the present invention is to provide a perfluorovinyl ether monomer that is easy to synthesize and low in cost.
Furthermore, another problem to be solved by the present invention is to provide a perfluorovinyl ether monomer suitable as a raw material for a polymer having high gas permeability.

上記課題を解決するために本発明に係るパーフルオロビニルエーテルモノマは、次の(1)式で表される構造を備えていることを要旨とする。

但し、
Rfは、炭素数が1〜10のパーフルオロカーボン基からなり、前記Rfは、枝分かれ、環状構造、又はエーテル結合を有していても良い。
Rf2は、それぞれ、炭素数が1〜10のパーフルオロカーボン基からなり、前記Rf2は、枝分かれ、環状構造、又はエーテル結合を有していても良い。 In order to solve the above problems, the gist of the perfluorovinyl ether monomer according to the present invention is that it has a structure represented by the following formula (1).
Figure 0006372758
However,
Rf 1 is composed of a perfluorocarbon group having 1 to 10 carbon atoms, and Rf 1 may have a branch, a cyclic structure, or an ether bond.
Rf 2 is a perfluorocarbon group having 1 to 10 carbon atoms, and Rf 2 may have a branched structure, a cyclic structure, or an ether bond.

(1)式で表されるパーフルオロビニルエーテルモノマは、パーフルオロビニルエーテル基を備えている。このパーフルオロビニルエーテル基は、スペーサ(−Rf1−)を介してパーフルオロカーボン基(−C(Rf2)3)とエーテル酸素(−O−)とが結合している構造を備えている。さらに、パーフルオロカーボン基(−C(Rf2)3)は、1つの炭素(C)から3つのパーフルオロカーボン基(−Rf2)への分岐を有する。
そのため、これを用いてコポリマ又はホモポリマを合成すると、パーフルオロビニルエーテル基の末端にある嵩高い(多分岐構造の)パーフルオロカーボン基(−C(Rf2)3)によりガス透過性が向上する。また、スペーサの無いパーフルオロビニルエーテル基を備えたモノマに比べて、コポリマ又はホモポリマの合成が容易化する。
The perfluorovinyl ether monomer represented by the formula (1) has a perfluorovinyl ether group. This perfluorovinyl ether group has a structure in which a perfluorocarbon group (—C (Rf 2 ) 3 ) and ether oxygen (—O—) are bonded via a spacer (—Rf 1 —). Further, the perfluorocarbon group (—C (Rf 2 ) 3 ) has a branch from one carbon (C) to three perfluorocarbon groups (—Rf 2 ).
Therefore, when a copolymer or a homopolymer is synthesized using this, the gas permeability is improved by the bulky (multi-branched structure) perfluorocarbon group (—C (Rf 2 ) 3 ) at the end of the perfluorovinyl ether group. In addition, the synthesis of a copolymer or a homopolymer is facilitated as compared with a monomer having a perfluorovinyl ether group without a spacer.

[2.2. Perfluoro dimer production process]

The reaction conditions between the dimer and fluorine are not particularly limited as long as the perfluoro dimer can be efficiently obtained.

[3. 作用]
(1)式で表されるパーフルオロビニルエーテルモノマは、パーフルオロビニルエーテル基を備えている。このパーフルオロビニルエーテル基は、スペーサ(−Rf1−)を介してパーフルオロカーボン基(−C(Rf2)3)とエーテル酸素(−O−)とが結合している構造を備えている。さらに、パーフルオロカーボン基(−C(Rf2)3)は、1つの炭素(C)から3つのパーフルオロカーボン基(−Rf2)への分岐を有する。
そのため、これを用いてコポリマ又はホモポリマを合成すると、パーフルオロビニルエーテル基の末端にある嵩高い(多分岐構造の)パーフルオロカーボン基(−C(Rf2)3)によりガス透過性が向上する。また、スペーサの無いパーフルオロビニルエーテル基を備えたモノマに比べて、コポリマ又はホモポリマの合成が容易化する。
[3. Action]
The perfluorovinyl ether monomer represented by the formula (1) has a perfluorovinyl ether group. This perfluorovinyl ether group has a structure in which a perfluorocarbon group (—C (Rf 2 ) 3 ) and ether oxygen (—O—) are bonded via a spacer (—Rf 1 —). Further, the perfluorocarbon group (—C (Rf 2 ) 3 ) has a branch from one carbon (C) to three perfluorocarbon groups (—Rf 2 ).
Therefore, when a copolymer or a homopolymer is synthesized using this, the gas permeability is improved by the bulky (multi-branched structure) perfluorocarbon group (—C (Rf 2 ) 3 ) at the end of the perfluorovinyl ether group. In addition, the synthesis of a copolymer or a homopolymer is facilitated as compared with a monomer having a perfluorovinyl ether group without a spacer.

このようなパーフルオロビニルエーテルモノマは、種々のアルコールとHFPOとを反応させ、必要に応じて、得られた2量体を直接フッ素化させることにより合成することができる。そのため、出発原料として安価な原料を用いることができ、モノマを低コスト化することができる。また、出発原料の制約が少ないので、種々の構造を備えたパーフルオロビニルエーテルモノマを合成することができる。
さらに、本発明に係るパーフルオロビニルエーテルモノマとTFEや酸基モノマとを共重合させると、得られたフッ素系ポリマは、嵩高さにより生まれる自由体積から、高いガス透過性を示す。
Such a perfluorovinyl ether monomer can be synthesized by reacting various alcohols with HFPO and, if necessary, directly fluorinating the obtained dimer. Therefore, an inexpensive raw material can be used as a starting raw material, and the monomer can be reduced in cost. In addition, since there are few restrictions on the starting materials, perfluorovinyl ether monomers having various structures can be synthesized.
Furthermore, when the perfluorovinyl ether monomer according to the present invention is copolymerized with TFE or an acid group monomer, the obtained fluorine-based polymer exhibits high gas permeability from a free volume produced by bulkiness.

[1. 化合物1(ネオペンチル2−ネオペントキシ−2,3,3,3−テトラフルオロプロピオネート)の合成]
マグネチックスターラーバー、ネオペンチルアルコール(4g、45mmol、東京化成)、フッ化ナトリウム微粉末(1.2g、28.6mmol、Wako)を、この順序でシュレンクチューブに入れ、ポリテトラフルオロエチレン製のコック栓をした。真空ポンプで脱気後、ヘリウム置換を3回繰り返した。反応容器を液体窒素で冷却し、HPFOガス(2.9g、17mmol)を導入した。
[1. Synthesis of Compound 1 (Neopentyl 2-neopentoxy-2,3,3,3-tetrafluoropropionate)]
Magnetic stirrer bar, neopentyl alcohol (4 g, 45 mmol, Tokyo Kasei), fine powder of sodium fluoride (1.2 g, 28.6 mmol, Wako) are put into a Schlenk tube in this order, and a cock made of polytetrafluoroethylene Plugged. After deaeration with a vacuum pump, helium replacement was repeated three times. The reaction vessel was cooled with liquid nitrogen and HPFO gas (2.9 g, 17 mmol) was introduced.

ネオペンチルアルコールの結晶は、30分程度室温で攪拌すると、次第に溶解し、ほぼ1:1の容積比で2層の透明な反応液相を形成した。室温で4時間攪拌すると、反応溶液は均一な単一の液相に変化した。さらに、室温で12時間攪拌した後、得られた透明な反応液をセミミクロ蒸留装置にて減圧下で蒸留し、透明な液体として目的物(化合物1)を得た(3.0g、48〜51℃/1mmHg、収率57%)。   When the neopentyl alcohol crystals were stirred at room temperature for about 30 minutes, they gradually dissolved to form a two-layer transparent reaction liquid phase with a volume ratio of approximately 1: 1. After stirring for 4 hours at room temperature, the reaction solution turned into a homogeneous single liquid phase. Furthermore, after stirring at room temperature for 12 hours, the obtained transparent reaction liquid was distilled under reduced pressure in a semi-micro distillation apparatus to obtain the desired product (Compound 1) as a transparent liquid (3.0 g, 48 to 51). ° C / 1 mmHg, 57% yield).

(Example 7: Synthesis of perfluoro (bornyl vinyl ether) monomer)
Unlike Example 1, the fluorination precursor was an ester of 2,2,2-trifluoroethanol. That is, borne borne borneol (containing 20% isoborneol) and 2,2,2-trifluoromethanol simultaneously to 2,2,2-trifluoroethyl 2- (bornyloxy) -2,3,3, 3-tetrafluoropropionate was synthesized.
Two diastereomers derived from borneol (Major A and B) and two diastereomers derived from isoborneol (Minor peak A and B) were each obtained as a mixture of 4: 1 (68-72 ° C / 0.40 mmHg, 12% yield). In the following MS, fragment ions having a relative intensity of about 5% or more were described. Common fragment ions were described taking into account the corresponding fragment ions of the structural isomers. Considering the corresponding fragment ions of structural isomers, common fragment ions are described even if the relative intensity is 5% or less, and fragment ions that are in the Major peak but not in the Minor peak are dared to be zero even if not observed.
