 ある種のフルオロ(ポリ)エーテル系化合物を含む組成物は、優れた撥水性、撥油性等を有する。例えば、特許文献1には、室温硬化型パーフルオロ(ポリ)エーテル組成物の硬化皮膜が表面に形成されたゴムについて記載されており、離型性、耐溶剤性、耐薬品性、耐候性、撥水性、撥油性等が付与されたゴムが提供されると記載されている。特許文献1の実施例には、パーフルオロ(ポリ)エーテル構造として、(OCFCF(CF))OCFCFO(CF(CF)CFO)(式中、m+n=90)を有する化合物を用いた組成物が記載されている。また、特許文献2~7には、パーフルオロ(ポリ)エーテル構造を有する湿気硬化性の組成物が記載されている。 Compositions containing certain fluoro(poly)ether compounds have excellent water repellency, oil repellency, and the like.

 パーフルオロ(ポリ)エーテル組成物の硬化物は撥水性、撥油性等を備えたゴムとして利用することができるため、接着剤とすると、接着部の安定性を高く保つことができる。しかしながら、フッ素化合物は概して非フッ素系の物質との親和性が良好ではない。このため、良好な密着性を備えた接着剤に対する需要が常に存在する。そこで本発明の課題は、各種基材に対する密着性に優れた硬化物を与える硬化性組成物を提供することにある。 The cured product of the perfluoro(poly)ether composition can be used as a rubber with water repellency, oil repellency, etc., so when used as an adhesive, the stability of the bonded part can be maintained at a high level. However, fluorine compounds generally do not have good affinity with non-fluorinated substances. Therefore, there is always a demand for adhesives with good adhesion. Accordingly, an object of the present invention is to provide a curable composition that gives a cured product having excellent adhesion to various substrates.

 本発明は特定の理論に束縛されるものではないが、-C(=O)NR-で表される構造はカルボニル基の酸素およびRが水素の場合の水素原子とが、水分子との水素結合の形成に関与しうる。一分子中における-C(=O)NR-で示される構造の数が増えることで、水素結合を生じる部分を多く備えることになり、硬化性組成物の硬化に関与する水分との親和性が増加する。このため、硬化性組成物の深部まで硬化反応が起こりやすくなり、好ましいと考えられる。したがって、前記一般式(I)においてkの値が1以上であることにより、PFPE含有シラン化合物(a)1分子あたりに含まれるアミド結合の数が多くなる。この構造が、水素結合による水分子との親和性向上をもたらしうるものであり、硬化性組成物の良好な深部硬化性に寄与するものと考えることができる。 Although the present invention is not bound by any particular theory, the structure represented by -C (=O) NR - can participate in the formation of hydrogen bonds between By increasing the number of structures represented by -C(=O)NR 7 - in one molecule, it is equipped with a large number of parts that generate hydrogen bonds, and affinity with moisture involved in curing of the curable composition increases. For this reason, the curing reaction tends to occur deep in the curable composition, which is considered preferable. Therefore, when the value of k in the general formula (I) is 1 or more, the number of amide bonds contained in one molecule of the PFPE-containing silane compound (a) increases. This structure can bring about improved affinity with water molecules through hydrogen bonding, and can be considered to contribute to good deep-part curability of the curable composition.
 前記-C(=O)NR-で表される構造におけるRは、各出現においてそれぞれ独立して、水素原子またはC1-20アルキル基を表す。Rは1分子あたり少なくとも4個存在するが、Rが水素である、すなわち、-C(=O)NH-で示される構造を有することで、得られる硬化性組成物が深部まで良好に硬化するようになるため好ましい。Rのうち少なくとも3つは水素原子であることが好ましく、全てのRが水素原子であることがより好ましい。Rの一部が水素原子である場合において、上記PFPE含有シラン化合物(a)中のどの位置にあるRが水素原子であるかは特に制限されない。上記PFPE含有シラン化合物(a)の調製において、原料の選択により-C(=O)NH-で示される構造が導入される位置を制御することができる。 Each occurrence of R 7 in the structure represented by -C(=O)NR 7 - independently represents a hydrogen atom or a C 1-20 alkyl group. At least four R 7 are present per molecule, and when R 7 is hydrogen, that is, by having a structure represented by -C(=O)NH-, the obtained curable composition can penetrate well to the deep part. It is preferable because it becomes hardened. At least three of R7 are preferably hydrogen atoms, and more preferably all R7 are hydrogen atoms. When part of R 7 is a hydrogen atom, there is no particular limitation on the position of the hydrogen atom in the PFPE-containing silane compound (a). In the preparation of the above PFPE-containing silane compound (a), the position at which the structure represented by -C(=O)NH- is introduced can be controlled by selecting raw materials.
 上記PFPE含有シラン化合物(a)は、前記-C(=O)NR-で表される構造が、その窒素原子を介してRまたはRで表される有機基と結合する。 In the PFPE-containing silane compound (a), the structure represented by -C(=O)NR 7 - is bonded to the organic group represented by R 5 or R 6 through the nitrogen atom.
 Rは、末端のケイ素原子とアミド結合とを連結するリンカーとして作用する基である。Rは、各出現において独立して、j+1価の有機基を表す。ここで、jの値は、上記PFPE含有シラン化合物(a)の末端に存在するケイ素原子を含む基の数を表し、その値は1~9の範囲である。よって、Rは、各出現において独立して、2~10価の有機基を表す。従って、当該Rは、上記PFPE含有シラン化合物(a)が安定に存在し得る2~10価の有機基であれば、いずれの基であってもよい。「2~10価の有機基」の定義は、先に示したとおりである。Rの具体的な例としては、後述する式(A)ないし(D)においてRに対応する部分として記載されているものを挙げることができる。Rは、好ましくは2~7価であり、より好ましくは2~4価であり、さらに好ましくは2価の有機基である。したがって、jの値は、好ましくは1~6であり、より好ましくは1~3であり、さらに好ましくは1である。 R5 is a group that acts as a linker connecting the terminal silicon atom and the amide bond. R5 independently at each occurrence represents a j+ 1 valent organic group. Here, the value of j represents the number of silicon atom-containing groups present at the ends of the PFPE-containing silane compound (a), and is in the range of 1-9. Thus, R 5 independently at each occurrence represents a divalent to decavalent organic group. Therefore, R 5 may be any group as long as it is a divalent to decavalent organic group in which the PFPE-containing silane compound (a) can stably exist. The definition of the “divalent to decavalent organic group” is as shown above. Specific examples of R 5 include those described as moieties corresponding to R 5 in formulas (A) to (D) described later. R 5 is preferably divalent to heptavalent, more preferably divalent to tetravalent, still more preferably a divalent organic group. Therefore, the value of j is preferably 1-6, more preferably 1-3, even more preferably 1.
 Rは、ケイ素原子とアミド結合とを直接連結する分子鎖上にヘテロ原子または芳香族の構造を有していないことが好ましく、芳香族の構造を有していないことがより好ましい。Rとしては、場合によりヘテロ原子を有していてもよい脂肪族炭化水素基であることが好ましく、より好ましくは非置換の脂肪族炭化水素であり、さらに好ましくは2価のアルキレン基である。Rとしてより好ましくはC1-20アルキレン基であり、さらに好ましくはC1-6アルキレン基であり、特に具体的には、メチレン基、エチレン基、プロピレン基、メチルエチレン基、ブチレン基、ヘキサメチレン基等である。上記PFPE含有シラン化合物(a)中に存在する二つのRは、同じであってもよく、異なっていてもよいが、化合物の調製が容易となることから、同じであることが好ましい。また、Rは、j+1個の結合手を有していることになるが、どの結合手で-C(=O)NR-部分と結合していてもよい。 R 5 preferably does not have a heteroatom or aromatic structure on the molecular chain directly connecting the silicon atom and the amide bond, and more preferably does not have an aromatic structure. R 5 is preferably an optionally heteroatom-containing aliphatic hydrocarbon group, more preferably an unsubstituted aliphatic hydrocarbon group, and still more preferably a divalent alkylene group. . R 5 is more preferably a C 1-20 alkylene group, more preferably a C 1-6 alkylene group, and more specifically, methylene group, ethylene group, propylene group, methylethylene group, butylene group, hexa methylene group and the like. The two R5's present in the PFPE - containing silane compound (a) may be the same or different, but are preferably the same to facilitate preparation of the compound. In addition, although R 5 has j+1 bonds, it may be bonded to the -C(=O)NR 7 - moiety with any bond.
 Rは、前記-C(=O)NR-で表される構造同士を連結する、2価の有機基であり、各出現においてそれぞれ独立して、-R22-R21-R23-で表される。 R 6 is a divalent organic group that connects the structures represented by -C(=O)NR 7 -, and each occurrence is independently -R 22 -R 21 -R 23 - is represented by

The perfluoro(poly)ether group-containing silane compound contained in the curable composition of the present invention contains a cycloalkylene group between amide bonds. Since the value of k in general formula (I) is 1 or more, the compound represented by general formula (I) has at least one alicyclic structure group represented by R 6 . The present invention is based on the discovery that the introduction of an alicyclic structure into a PFPE-containing compound enhances adhesion to a substrate when used as an adhesive.

 R部分は、例えばPFPEの両末端に、アミド結合を介してRまたはRと結合を形成可能な反応性官能基を有する化合物(以下、このような化合物を「PFPE変性体」といい、例えば末端がエステル基の場合の当該化合物を「PFPEエステル変性体」ということがある)に対し、ジアミンを作用させることにより、導入することができる。分子鎖中のR部分の個数(換言するとkの値)は、反応物の量関係を調整することで操作することができる。 The R6 moiety is, for example, a compound having a reactive functional group at both ends of PFPE1 that can form a bond with R5 or R6 via an amide bond ( hereinafter, such a compound is referred to as a "PFPE modified form"). For example, a compound having an ester group at the end thereof is sometimes referred to as a "modified PFPE ester"), and can be introduced by reacting a diamine. The number of R6 moieties in the molecular chain (in other words the value of k) can be manipulated by adjusting the quantity relationships of the reactants.
 上記PFPE含有シラン化合物(a)は、その分子末端の構造として、R 3-pSi-またはR 3-qSi-で表される構造を有する。R、R、p、qの定義は、先に示したとおりである。すなわち、上記PFPE含有シラン化合物(a)の分子末端には、水酸基または加水分解可能な基が少なくとも1つケイ素原子に結合した構造が存在する。「加水分解可能な基」は、上記と同意義である。1分子または1つの分子末端構造中のR、Rには、各々異なる基が混在していてもよい。水酸基または加水分解可能な基が2つまたは3つケイ素原子に結合した構造は、分子の各末端にj個存在する。jの値は1~9の範囲である。したがって、PFPE含有シラン化合物(a)は、少なくとも2個の上記末端構造を有している。好ましくはjの値は1である。すなわち、好ましい一態様において、PFPE含有シラン化合物(a)は、加水分解可能な基が結合したケイ素を両末端に有する、直鎖状の分子である。 The PFPE-containing silane compound (a) has a structure represented by R 3 p R 4 3-p Si— or R 3 q R 4 3-q Si— as its molecular terminal structure. The definitions of R 3 , R 4 , p and q are as given above. That is, the PFPE-containing silane compound (a) has a structure in which at least one hydroxyl group or hydrolyzable group is bonded to a silicon atom at the molecular terminal. "Hydrolyzable group" has the same meaning as above. Different groups may be mixed in R 3 and R 4 in one molecule or in one molecular terminal structure. Structures in which two or three hydroxyl groups or hydrolyzable groups are bonded to silicon atoms are present at each end of the molecule. The value of j ranges from 1-9. Therefore, the PFPE-containing silane compound (a) has at least two terminal structures. Preferably the value of j is one. That is, in a preferred embodiment, the PFPE-containing silane compound (a) is a linear molecule having silicon at both ends to which hydrolyzable groups are bonded.
 上記式中、Rは、各出現においてそれぞれ独立して、水素原子または1価の有機基である。Rとして好ましくは炭素原子数1~22のアルキル基、より好ましくは炭素原子数1~4のアルキル基である。 In the above formula, each occurrence of R 3 is independently a hydrogen atom or a monovalent organic group. R 3 is preferably an alkyl group having 1 to 22 carbon atoms, more preferably an alkyl group having 1 to 4 carbon atoms.
 Rは、水酸基または加水分解可能な基であるが、加水分解可能な基であることが好ましい。加水分解可能な基の例としては、先に記載したとおりであるが、これらの中でも、特に、-OR(ここで、Rは、置換または非置換の炭素原子数1~4のアルキル基を示す)、即ち、アルコキシ基が好ましい。アルコキシ基の例には、メトキシ基、エトキシ基、プロポキシ基、イソプロポキシ基、n-ブトキシ基、イソブトキシ基などの非置換アルコキシ基;クロロメトキシ基などの置換アルコキシ基が挙げられる。それらの中でも、メトキシ基またはエトキシ基がより好ましい。 R 4 is a hydroxyl group or a hydrolyzable group, preferably a hydrolyzable group. Examples of hydrolyzable groups are as described above, among these, especially -OR, where R represents a substituted or unsubstituted alkyl group of 1 to 4 carbon atoms ), ie an alkoxy group. Examples of alkoxy groups include unsubstituted alkoxy groups such as methoxy, ethoxy, propoxy, isopropoxy, n-butoxy and isobutoxy groups; substituted alkoxy groups such as chloromethoxy groups. Among them, a methoxy group or an ethoxy group is more preferable.
 pまたはqは、それぞれ0~3の整数である。ただし、(SiR 3-pにおいて少なくとも1つのSiR 3-pは、pが0~2の整数であり、(SiR 3-qにおいて少なくとも1つのSiR 3-qは、qが0~2の整数である。pまたはqは、それぞれ0または1である。0であることが好ましい。したがって、PFPE含有シラン化合物(a)は、水酸基または加水分解可能な基が2つまたは3つケイ素原子に結合した構造を有する。また、PFPE含有シラン化合物(a)の分子末端の構造は、トリアルコキシシリル基であることが好ましく、トリメトキシシリル基であることがより好ましい。 p or q is an integer from 0 to 3 respectively. provided that at least one SiR 3 p R 4 3 - p in (SiR 3 p R 4 3 - p ) j is an integer of 0 to 2 , and at least In one SiR 3 q R 4 3-q , q is an integer of 0-2. p or q is 0 or 1, respectively. 0 is preferred. Therefore, the PFPE-containing silane compound (a) has a structure in which two or three hydroxyl groups or hydrolyzable groups are bonded to silicon atoms. The structure of the molecular terminal of the PFPE-containing silane compound (a) is preferably a trialkoxysilyl group, more preferably a trimethoxysilyl group.
 特に好ましい態様において、PFPE含有シラン化合物(a)は、Rが全て水素原子であり、Rが2価のアルキレン基であり、Rがシクロヘキシル基を2つ有する基であり、jが1であり、pおよびqが0である、化合物である。PFPE含有シラン化合物(a)は、1種の化合物を単独で用いてもよく、2種以上の混合物として用いてもよい。 In a particularly preferred embodiment, in the PFPE-containing silane compound (a), R 7 are all hydrogen atoms, R 5 is a divalent alkylene group, R 6 is a group having two cyclohexyl groups, and j is 1. and p and q are zero. The PFPE-containing silane compound (a) may be used singly or as a mixture of two or more.
 PFPE含有シラン化合物(a)の調製方法によっては、PFPE変性体またはPFPE変性体がRで連結された化合物の、片方または両方の末端部分にシリル基および場合によりリンカー部分が導入されていない構造の化合物が生じ得る。以下、このようなPFPEから構成される分子鎖両末端の少なくとも一方にシリル基を含まない化合物を「非末端化PFPE変性体」と表記することがある。一般式(I)で表される化合物の純度は高い方が好ましい。つまりこのような非末端化PFPE変性体の含有割合は小さい方が好ましいが、硬化性組成物としての機能を損なわない範囲において、硬化性組成物の調製に用いられるPFPE含有シラン化合物(a)は非末端化PFPE変性体を含んでいてもよい。例えば、前記一般式(I)の場合、{-PFPE-C(=O)NR-R-NRC(=O)-}-PFPE-で示される構造にカルボン酸基、エステル基、水酸基またはアルキレン-OH基が結合したような構造の化合物を含んでいてもよい。 Depending on the method for preparing the PFPE-containing silane compound (a), a structure in which a silyl group and optionally a linker moiety are not introduced at one or both terminal portions of the modified PFPE or the compound in which the modified PFPE is linked at R 6 can result. Hereinafter, such a compound that does not contain a silyl group on at least one of both ends of the molecular chain composed of PFPE 1 may be referred to as "non-terminated modified PFPE". The higher the purity of the compound represented by formula (I), the better. In other words, it is preferable that the content of such non-terminated PFPE modified product is small, but the PFPE-containing silane compound (a) used for preparing the curable composition is Non-terminated PFPE modifications may be included. For example, in the case of general formula (I), {-PFPE 1 -C(=O)NR 7 -R 6 -NR 7 C(=O)-} k -PFPE 1 - has a carboxylic acid group, A compound having a structure in which an ester group, a hydroxyl group, or an alkylene-OH group is bonded may be included.
 硬化性組成物の調製に用いられるPFPE含有シラン化合物(a)の純度は、シリル基がどの程度末端に導入されているか、シランでの末端化率をその尺度とすることができる。末端化率は、PFPE部分のうち、Rで挟まれていないものの物質量の合計に対し、当該部分にシリル基が導入されているものの割合により求められる。末端化率は90モル%以上であることが好ましく、93モル%以上であることがより好ましく、95モル%以上であることがさらに好ましい。この範囲とすることで、分子の両末端がシリル化された化合物を十分な量で含有することができ、硬化性組成物としての機能を十分に発揮することができる。
 末端化率は、例えばNMR測定により決定することができる。一般式(I)の化合物の場合、PFPEの末端に存在するCF基、即ちリンカーと結合しているアミド基に隣接するCF基を19F NMRで測定することで、分子末端にどの程度シリル基が導入されているかを求めることができる。一般式(I)の化合物とは異なる構造を有する化合物においても、末端がシリル化されたものとそうでないものとで異なる部分のNMR測定によって末端化率を算出することができ、その方法は、当業者にとって周知である。
The purity of the PFPE-containing silane compound (a) used in the preparation of the curable composition can be measured by the extent to which silyl groups are introduced at the terminals, or the degree of terminalization with silane. The termination rate is obtained from the ratio of the portion having a silyl group introduced into the portion to the total amount of substances not sandwiched by R 6 among the 1 portion of PFPE. The termination rate is preferably 90 mol % or more, more preferably 93 mol % or more, and even more preferably 95 mol % or more. Within this range, the compound having both ends of the molecule silylated can be contained in a sufficient amount, and the function as a curable composition can be sufficiently exhibited.
The termination ratio can be determined, for example, by NMR measurement. In the case of the compound of general formula (I), the CF 2 group present at the end of PFPE 1 , that is, the CF 2 group adjacent to the amide group bonded to the linker was measured by 19 F NMR to determine which It is possible to determine the extent to which silyl groups have been introduced. Even in a compound having a structure different from that of the compound of general formula (I), the termination rate can be calculated by NMR measurement of the different portions depending on whether the terminal is silylated or not, and the method is as follows. well known to those skilled in the art.
 以下、上記PFPE含有シラン化合物(a)の一態様として、具体的な構造について詳述する。上記PFPE含有シラン化合物(a)は、式(A)、(B)、(C)、または(D)で表される少なくとも1種の化合物であることが好ましい。以下の式において現れる各基および添え字は、それぞれ前記一般式に現れる基および添え字に対応させることができ、当業者であれば各々の対応関係を把握することができるものである。 A specific structure will be described in detail below as one aspect of the PFPE-containing silane compound (a).

 上記式中、Xは、それぞれ独立して、2~10価の有機基を表す。すなわち、Xは、上記一般式のRに対応する。当該Xは、式(C)で表される化合物において、主に撥水性および表面滑り性等を提供するパーフルオロ(ポリ)エーテル部(即ち、-PFPE-部)と、基材との結合能を提供するシラン部(具体的には、-SiR k1 l1 m1基、または-SiRa” k1b” l1c” m1基)とを連結するリンカーと解される。従って、当該Xは、式(C)で表される化合物が安定に存在し得るものであれば、いずれの有機基であってもよい。なお、本明細書において、Xとして記載している構造は、左側がPFPEで表される基に、右側がγ1を付して括弧でくくられた基に、それぞれ結合する。 In the above formula, each X 5 independently represents a divalent to decavalent organic group. That is, X5 corresponds to R5 in the above general formula. The X 5 is a perfluoro(poly)ether portion (that is, -PFPE 1 - portion) that mainly provides water repellency and surface slipperiness in the compound represented by formula (C), and the base material. It is understood as a linker that connects a silane moiety that provides binding ability (specifically, a -SiR a k1 R b l1 R c m1 group or a -SiR a″ k1 R b″ l1 R c″ m1 group). Therefore, X 5 may be any organic group as long as the compound represented by formula ( C) can exist stably. The structure is attached to the group represented by PFPE 1 on the left side and to the group bracketed with γ1 on the right side, respectively.
