Description

  The present invention relates to an acrylic pressure-sensitive adhesive. More specifically, the present invention relates to an acrylic pressure-sensitive adhesive having a vinyl polymer having a (meth) acryloyl group at the molecular terminal and an acrylic monomer as essential components.

Acrylic adhesives have well-balanced adhesive properties without the addition of tackifying resins and are produced in large quantities alongside natural rubber adhesives.
In general, acrylic pressure-sensitive adhesives are applied to a substrate with a pressure-sensitive adhesive solution obtained by solution polymerization of a vinyl monomer containing an acrylic monomer as a main component with an organic solvent, or an emulsion obtained by emulsion polymerization in an aqueous system. Alternatively, it is obtained by impregnation and drying by heating.
Acrylic pressure-sensitive adhesives are generally improved by cross-linking because they have a particularly insufficient cohesive force due to problems of molecular weight and molecular weight distribution. Various types of crosslinking methods have been developed. For example, a method of adding a crosslinking agent such as a polyisocyanate compound, an epoxy compound, a polyvalent carboxylic acid, a polyamine compound, a phenol resin, or a sulfur compound has been proposed.

  However, when such a cross-linking agent is added, a portion other than acrylic is included in the structure, and heat resistance and weather resistance are expected to be reduced.

  In addition, it has a polymerizable group at one end, and an acrylic oligomer or acrylic polymer having a relatively low viscosity due to its low dispersibility is copolymerized to construct an ordered comb structure, and adhesive physical properties such as adhesive strength No method has been reported to improve

The present inventors have so far reported an acrylic polymer obtained by living radical polymerization as a main chain and a polymer having a (meth) acryloyl group at the terminal (Patent Document 1). There is no mention of modification of the agent or use as a crosslinking agent.

<About the manufacturing method of (A) component>
It does not specifically limit about the manufacturing method of the said (A) component. The vinyl polymer is generally produced by anionic polymerization or radical polymerization, but radical polymerization is preferred because of the versatility of the monomer or ease of control. Among radical polymerizations, it is preferably produced by living radical polymerization or radical polymerization using a chain transfer agent, and the former is particularly preferable.
The radical polymerization method used in the method for synthesizing the component (A) simply copolymerizes a monomer having a specific functional group and a vinyl monomer using an azo compound, a peroxide, or the like as a polymerization initiator. They can be classified into “general radical polymerization methods” and “controlled radical polymerization methods” in which specific functional groups can be introduced at controlled positions such as terminals.
The “general radical polymerization method” is a simple method. However, in this method, a monomer having a specific functional group is introduced into the polymer only in a probabilistic manner, so an attempt is made to obtain a polymer having a high functionalization rate. In such a case, it is necessary to use this monomer in a considerably large amount. On the contrary, if the monomer is used in a small amount, there is a problem that the proportion of the polymer in which this specific functional group is not introduced becomes large. Further, since it is free radical polymerization, there is a problem that only a polymer having a wide molecular weight distribution and a high viscosity can be obtained.
The “controlled radical polymerization method” further includes a “chain transfer agent method” in which a vinyl polymer having a functional group at a terminal is obtained by polymerization using a chain transfer agent having a specific functional group, It can be classified as a “living radical polymerization method” in which a polymer having a molecular weight almost as designed is obtained by growing the terminal without causing a termination reaction or the like.
In the “chain transfer agent method”, a polymer having a high functionalization rate can be obtained, but a chain transfer agent having a considerably large amount of a specific functional group with respect to the initiator is required. There is an economic problem. Further, like the above-mentioned “general radical polymerization method”, there is also a problem that only a polymer having a wide molecular weight distribution and a high viscosity can be obtained because of free radical polymerization.
Unlike these polymerization methods, the “living radical polymerization method” is a radical polymerization that is difficult to control because the polymerization rate is high and a termination reaction due to coupling between radicals is likely to occur. It is difficult to obtain a polymer having a narrow molecular weight distribution (Mw / Mn is about 1.1 to 1.5), and the molecular weight can be freely controlled by the charging ratio of the monomer and the initiator.
Accordingly, the “living radical polymerization method” can obtain a polymer having a narrow molecular weight distribution and a low viscosity, and a monomer having a specific functional group can be introduced at almost any position of the polymer. The method for producing the vinyl polymer having the specific functional group is more preferable.
In the narrow sense, living polymerization refers to polymerization in which the terminal always has activity and the molecular chain grows, but in general, the terminal is inactivated and the terminal is activated. It also includes pseudo-living polymerization that grows in an equilibrium state. The definition in the present invention is also the latter.
The “living radical polymerization method” has been actively researched by various groups in recent years. Examples thereof include those using a cobalt porphyrin complex as shown in, for example, Journal of American Chemical Society (J. Am. Chem. Soc.), 1994, 116, 7943, Macromolecules. (Macromolecules), 1994, Vol. 27, p. 7228, using a radical scavenger such as a nitroxide compound, etc., “atom transfer radical polymerization” using an organic halide as an initiator and a transition metal complex as a catalyst ( Atom Transfer Radical Polymerization (ATRP).
Among the “living radical polymerization methods”, the “atom transfer radical polymerization method” in which a vinyl monomer is polymerized using an organic halide or a sulfonyl halide compound as an initiator and a transition metal complex as a catalyst is the above “living radical polymerization method”. In addition to the characteristics of `` legal method '', it has a halogen which is relatively advantageous for functional group conversion reaction at the end, and has a great degree of freedom in designing initiators and catalysts. It is further preferable as a manufacturing method.
As this atom transfer radical polymerization method, for example, Matyjazewski et al., Journal of American Chemical Society (J. Am. Chem. Soc.) 1995, 117, 5614; Macromolecules 1995 28, 7901; Science 1996, 272, 866; WO 96/30421; WO 97/18247; or Sawamoto et al., Macromolecules, 1995, 28, 1721. Page and the like.
In the present invention, there is no particular restriction as to which of these methods is used, but basically, controlled radical polymerization is utilized, and living radical polymerization is preferred from the viewpoint of ease of control, and particularly, atom transfer radical polymerization method. Is preferred.
First, one of controlled radical polymerizations, polymerization using a chain transfer agent will be described. Although it does not specifically limit as radical polymerization using a chain transfer agent (telomer), The following two methods are illustrated as a method of obtaining the vinyl polymer which has the terminal structure suitable for this invention.
JP-A-4-132706 discloses a method for obtaining a halogen-terminated polymer by using a halogenated hydrocarbon as a chain transfer agent, JP-A-61-271306, JP-A-2594402, This is a method for obtaining a hydroxyl-terminated polymer by using a hydroxyl group-containing mercaptan or a hydroxyl group-containing polysulfide as a chain transfer agent as disclosed in JP-A-54-47782.
Next, living radical polymerization will be described.
First, a method using a radical scavenger such as a nitroxide compound will be described. In this polymerization, a stable nitroxy free radical (= N—O.) Is generally used as a radical scavenger. Examples of such compounds include, but are not limited to, 2,2,6,6-substituted-1-piperidinyloxy radical, 2,2,5,5-substituted-1-pyrrolidinyloxy radical, and the like. Nitroxy free radicals from cyclic hydroxyamines are preferred. As the substituent, an alkyl group having 4 or less carbon atoms such as a methyl group or an ethyl group is suitable. Specific nitroxy free radical compounds include, but are not limited to, 2,2,6,6-tetramethyl-1-piperidinyloxy radical (TEMPO), 2,2,6,6-tetraethyl-1- Piperidinyloxy radical, 2,2,6,6-tetramethyl-4-oxo-1-piperidinyloxy radical, 2,2,5,5-tetramethyl-1-pyrrolidinyloxy radical, 1, Examples include 1,3,3-tetramethyl-2-isoindolinyloxy radical, N, N-di-t-butylamineoxy radical, and the like. Instead of the nitroxy free radical, a stable free radical such as a galvinoxyl free radical may be used.
The radical scavenger is used in combination with a radical generator. It is considered that the reaction product of the radical scavenger and the radical generator serves as a polymerization initiator and the polymerization of the addition polymerizable monomer proceeds. The combined ratio of both is not particularly limited, but 0.1 to 10 mol of the radical generator is appropriate for 1 mol of the radical scavenger.
As the radical generator, various compounds can be used, but a peroxide capable of generating a radical under the polymerization temperature condition is preferable. Examples of the peroxide include, but are not limited to, diacyl peroxides such as benzoyl peroxide and lauroyl peroxide, dialkyl peroxides such as dicumyl peroxide and di-t-butyl peroxide, diisopropyl peroxydicarbonate, bis There are peroxycarbonates such as (4-t-butylcyclohexyl) peroxydicarbonate, alkyl peresters such as t-butylperoxyoctoate and t-butylperoxybenzoate. Benzoyl peroxide is particularly preferable. Furthermore, radical generators such as radical-generating azo compounds such as azobisisobutyronitrile may be used instead of peroxide.
As reported in Macromolecules 1995, 28, 2993, instead of using a radical scavenger and a radical generator together, an alkoxyamine compound represented by the following formula may be used as an initiator.

Ｒ⁹は、直接結合、又は、１個以上のエーテル結合を含んでいても良い炭素数１〜２０の２価の有機基であるが、Ｒ⁹が直接結合である場合は、ハロゲンが結合している炭素にビニル基が結合しており、ハロゲン化アリル化物である。この場合は、隣接ビニル基によって炭素−ハロゲン結合が活性化されているので、Ｒ¹⁰としてＣ（Ｏ）Ｏ基やフェニレン基等を有する必要は必ずしもなく、直接結合であってもよい。Ｒ⁹が直接結合でない場合は、炭素−ハロゲン結合を活性化するために、Ｒ¹⁰としては−Ｃ（Ｏ）Ｏ−、−Ｃ（Ｏ）−、フェニレン基が好ましい。

R ⁹ is a direct bond or a divalent organic group having 1 to 20 carbon atoms which may contain one or more ether bonds. When R ⁹ is a direct bond, a halogen is bonded. A vinyl group is bonded to the carbon, and is a halogenated allylic compound. In this case, since the carbon-halogen bond is activated by the adjacent vinyl group, it is not always necessary to have a C (O) O group or a phenylene group as R ¹⁰ , and a direct bond may be used. When R ⁹ is not a direct bond, R ¹⁰ is preferably —C (O) O—, —C (O) — or a phenylene group in order to activate the carbon-halogen bond.
