Description

【0001】
【発明の属する技術分野】
本発明は、重合性高分子化合物、その製造方法、並びに前記重合性高分子化合物を製造するための合成中間体高分子化合物に関し、更に詳細には、紫外線や電子線で短時間に硬化させることが可能で、プラスチック基材との高密着性が期待でき、かつ硬度、染色性等に優れる反射防止膜等の光学用樹脂の原材料等として好適に利用しうる高屈折率を示す重合性高分子化合物、その製造方法、並びに合成中間体高分子化合物に関する。
【0002】
【従来の技術】
近年、プラスチック材料は、耐衝撃性、軽量性、易成形性、加工性等の特性を活かしてガラスに代わる材料として広く利用されている。しかし、プラスチック材料は、表面硬度が低く傷つき易いため、種々のハードコート剤で被覆して耐擦傷性を向上させている(特開昭57−2735号公報、特開昭59−204669号公報)。一方、光学多層膜(選択反射膜、選択透過膜等)として利用するには高い屈折率(例えば、1.60を超える屈折率)が要求される。しかし、このような高屈折率を有するプラスチック材料は少なく、また高屈折率材料は、透明性や着色の問題を有しており、実用に適さないという問題点がある。
【0003】
従って、現在利用されている光学多層膜は、無機材料の蒸着によって作製されている。このような蒸着による作製では、大面積化が困難であり、且つコスト高になるため、潜在的な市場要求はあるものの汎用的に利用されるには至っていないのが実状である。そこで、簡便な塗工方法によって膜を形成し得るプラスチック高屈折率材料が要望されている。
【0004】
ところで、ベンゾチアゾール骨格を有するモノマー組成物や該組成物を重合させた高屈折率樹脂(例えば、特開平2−29401号公報、特開平2−265907号公報、特開平4−257531号公報、特開平4−225007号公報、特開平4−300909号公報)、並びにナフタレン骨格を有するプラスチックレンズ材料や高屈折率樹脂(例えば、特開昭62−276501号公報、特開平1−242608号公報)について提案がなされている。しかしながら、これら従来技術に提案されている高分子化合物は、いずれも重合性基を有するものではなく、重合性基を有する高屈折材料となりうる高分子化合物については知られていない。
【0005】
【発明が解決しようとする課題】
本発明の目的は、紫外線や電子線で短時間に硬化させることが可能であり、プラスチック基材との高密着性が期待でき、且つ硬度、染色性等に優れる反射防止膜等の光学用樹脂の原材料等として好適に利用することができる高屈折率を示す重合性高分子化合物及びその製造方法を提供することにある。
本発明の別の目的は、前記重合性高分子化合物の製造に利用し、重合性高分子化合物を高い生産効率で製造することを可能にした合成中間体高分子化合物を提供することにある。
【0006】
【課題を解決するための手段】
本発明によれば、下記一般式(1)及び(2)で表される繰返し単位を含み、数平均分子量が2000〜2000000であり、好ましくは一般式(1)で表される繰返し単位と、一般式(2)で表される繰返し単位の含有比率が、モル比で5〜95:95〜5である重合性高分子化合物が提供される。

【0008】
また、本発明によれば、前記重合性高分子化合物の中間体高分子であって、前記一般式(1)及び下記一般式(3)で表される繰返し単位を含み、数平均分子量が2000〜2000000である合成中間体高分子化合物が提供される。
【0009】
【化4】

【0010】
更に、本発明によれば、前記合成中間体高分子化合物と、(メタ)アクリル酸ハライドとを反応させることを特徴とする前記重合性高分子化合物の製造方法が提供される。
【0011】
【発明の実施の形態】
本発明の重合性高分子化合物は、前記一般式(1)及び(2)で表される繰返し単位を有する。これらの繰返し単位は、ランダム若しくはブロックのいずれに配置していても良い。一般式(1)においてnは1以上の正数であって、好ましくは1〜5の正数である。また、一般式(2)においてmは1以上の正数であって、好ましくは1〜5の正数である。一般式(1)及び(2)において、X、Zで表されるフッ素原子を除くハロゲン原子としては、塩素原子、臭素原子、ヨウ素原子が好ましい。
【0012】
本発明の重合性高分子化合物の数平均分子量は、2000〜2000000、好ましくは5000〜1000000である。2000未満の場合には、形態が液状となり精製が困難であり、2000000を超えると溶媒への溶解性が著しく悪くなる。また、本発明の重合性高分子化合物は、高屈折率を示し、通常1.60以上の屈折率を示す。
【0013】
一般式(1)及び(2)で表される繰返し単位の組合わせは、特に限定されるものではなく、いかなる組合わせであっても良い。代表的には後述する一般式(1)及び(2)で表される繰返し単位を構成する単量体の例示の各々の組合わせや実施例の組合せを好ましく挙げることができる。
【0014】
本発明の重合性高分子化合物において、一般式(1)及び(2)で表される繰返し単位の各々の含有割合は、好ましくはモル比で5〜95:95〜5、特に好ましくは25〜90:75〜10の範囲である。一般式(1)で表される繰返し単位の含有割合が5モル%未満の場合には、重合性基の割合が十分でなく、95モル%を超える場合には屈折率が低くなるので好ましくない。
【0015】
本発明の合成中間体高分子化合物は、前記重合性高分子化合物を製造する際に用いる中間体であり、前記一般式(1)及び(3)で表される繰返し単位を有する。即ち、前記重合性高分子化合物を構成する一般式(2)で表される繰返し単位における−OCOC(R2)=CH2を−R3(ヒドロキシル基又はアミノ基)とした以外は、前記重合性高分子化合物と同様であり、好ましい繰返し単位の組合わせも、一般式(2)で表される繰返し単位における−OCOC(R2)=CH2を−R3に代えたものを好ましく例示できる。従って、本発明の合成中間体高分子化合物の数平均分子量は、2000〜2000000、好ましくは5000〜1000000である。また、一般式(1)及び(3)で表される繰返し単位の各々の含有割合は、好ましくはモル比で5〜95:95〜5、特に好ましくは25〜90:75〜10の範囲である。
【0016】

【0019】
合成中間体高分子化合物を調製する際に使用できるラジカル重合開始剤としては、特に限定されず、公知のものが使用できる。例えば、ベンゾイルパーオキサイド、p−クロロベンゾイルパーオキサイド、デカノイルパーオキサイド、ラウロイルパーオキサイド、アセチルパーオキサイド等のジアシルパーオキサイド;t−ブチルパーオキシネオデカネート、クミルパーオキシネオデカネート、t−ブチルパーオキシベンゾエート等のパーオキシエステル;ジイソプロピルパーオキシジカーボネート、ジ−2−エチルヘキシルパーオキシジカーボネート、ジ−sec−ブチルパーオキシジカーボネート等のパーカーボネート;2,2’−アゾビスイソブチロニトリル、2,2’−アゾビス(4−メトキシ−2,4−ジメチルバレロニトリル)、2,2’−アゾビス(2,4−ジメチルバレロニトリル)、2,2’−アゾビス(2−メチルブチロニトリル)、1,1’−アゾビス(シクロヘキサン−1−カルボニトリル)等のアゾ化合物等を挙げることができる。
【0020】
ラジカル重合開始剤の使用量は、重合条件や開始剤の種類、単量体A及びBの組成によって異なり、一概に限定できないが、一般には単量体の合計量100重量部に対して0.01〜10重量部、好ましくは0.01〜5重量部の範囲が好適である。
【0021】
重合条件は、特に温度が得られる合成中間体高分子の性状に影響を与えるが、この温度条件は開始剤の種類や量、単量体の種類によって決定されるので一概には限定できない。通常、30〜120℃で重合を開始し、重合終了時に高温下で重合を終了させる2段重合が好適である。重合時間も温度と同様に各種の要因によって異なるので、予めこれらの条件に応じた最適の時間を決定するのが好ましいが、一般には1〜40時間で重合が完結するように条件を設定するのが望ましい。反応終了後、再沈澱等の公知の精製法により目的の合成中間体高分子化合物を得ることができる。また、溶液重合により合成中間体高分子化合物を調製した場合、前記重合性高分子化合物の製造にあたっては、精製せずにそのまま次の反応を行なうことも可能である。
【0022】
本発明の重合性高分子化合物の製造方法では、前記合成中間体高分子化合物と(メタ)アクリル酸ハライドとを反応させることにより得ることができる。

(メタ)アクリル酸ハライドとしては、アクリル酸クロリド、アクリル酸ブロミド、メタクリル酸クロリド、メタクリル酸ブロミド等を挙げることができる。この(メタ)アクリル酸ハライドの仕込み量は、合成中間体高分子化合物中の単量体Bに相当する繰返し単位と反応させる量であり、通常、合成中間体高分子化合物製造時の単量体仕込み量に対して、1〜3当量程度が好ましい。
【0024】
前記合成中間体高分子化合物と(メタ)アクリル酸ハライドとを反応させるには、合成中間体高分子化合物が可溶であって、反応を阻害しない溶媒を用いて行なうことができる。溶媒としては、ベンゼン、トルエン、キシレン等のアルキル置換ベンゼン類;クロロベンゼン、ジクロロベンゼン、ブロモベンゼン等のハロゲン置換ベンゼン類;テトラヒドロフラン、ジエチルエーテル、ジプロピルエーテル等のジアルキルエーテル類;クロロホルム、メチレンクロリド、メチレンブロミド、エチレンジクロリド、エチレンジブロミド等のハロゲン置換アルキル等が好ましい。また、この反応の際に生成するハロゲン化水素を反応系外に除去するために、適当な塩基を添加して反応させるのが好ましい。このような塩基としては、トリエチルアミン、トリプロピルアミン、トリブチルアミン等のトリアルキルアミン類;ピリジン、ジメチルアニリン、テトラメチル尿素等を挙げることができる。更に、反応の際に重合性基が重合するのを防止するために、t−ブチルカテコール等の重合禁止剤を添加しても良い。
【0025】
反応条件は、合成中間体高分子化合物の種類等により異なり、一概に限定できないが、反応温度は−50〜120℃、特に−20〜30℃が好ましく、反応時間は10分間〜24時間が望ましい。反応の終点は、液体クロマトグラフィーや赤外吸収スペクトル等で確認できる。反応終了後、再沈澱等の公知の方法により精製して目的の重合性高分子化合物を得ることができる。
【0026】
本発明の重合性高分子化合物を光学樹脂用薄膜とするには、重合性高分子化合物に必要に応じて硬化開始剤や耐擦傷性等を向上させるための架橋剤等を添加混合した後、通常行なわれる塗布方法、例えばロールコート法、グラビアコート法、ディップコート法及びスピンコート法等によりプラスチック等の基材に塗布し、乾燥させ、次いで、紫外線、電子線、放射線等の活性エネルギー線の照射又は加熱硬化等により重合硬化させることにより得ることができる。特に効率良く生産するためには、連続的にグラビアコート法等で基材に塗布し、直ちに活性エネルギー線照射法で硬化させるのが望ましい。この際、重合性高分子化合物には、紫外線吸収剤、酸化防止剤、着色剤、帯電防止剤、蛍光塗料、染料、顔料等の各種安定剤、添加剤を必要に応じて添加することもできる。
【0027】
前記硬化開始剤としては、例えば、ベンゾイルパーオキサイド、p−クロロベンゾイルパーオキサイド、デカノイルパーオキサイド、ラウロイルパーオキサイド、アセチルパーオキサイド等のジアシルパーオキサイド;t−ブチルパーオキシネオデカネート、クミルパーオキシネオデカネート、t−ブチルパーオキシベンゾエート等のパーオキシエステル;ジイソプロピルパーオキシジカーボネート、ジ−2−エチルヘキシルパーオキシジカーボネート、ジ−sec−ブチルパーオキシジカーボネート等のパーカーボネート;2,2’−アゾビスイソブチロニトリル、2,2’−アゾビス(4−メトキシ−2,4−ジメチルバレロニトリル)、2,2’−アゾビス(2,4−ジメチルバレロニトリル)、2,2’−アゾビス(2−メチルブチロニトリル)、1,1’−アゾビス(シクロヘキサン−1−カルボニトリル)等のアゾ化合物等を挙げることができる。
【0028】
硬化開始剤の使用量は、重合条件や開始剤の種類、重合性高分子化合物の種類によって異なり、一概に限定できないが、一般には重合性高分子化合物100重量部に対して0.01〜10重量部、好ましくは0.01〜5重量部の範囲が好適である。
【0029】
前記架橋剤としては、例えば、重合性不飽和基を2個以上有する多官能性モノマー、具体的には、ジ(メタ)アクリル酸ヘキサンジオール、ジ(メタ)アクリル酸ノナンジオール、ジ(メタ)アクリル酸ネオペンチルグリコール、ジ(メタ)アクリル酸トリシクロデカンジメタノール、トリ(メタ)アクリル酸ペンタエリスリトール、トリス(アクリロキシメチル)イソシアネート、ジビニルベンゼン、エチレングリコールジ(メタ)アクリレート等を好ましく挙げることができる。架橋剤の配合割合は種類によって異なり一概に限定できないが、重合性高分子化合物100重量部に対して、70重量部以下、好ましくは50重量部以下が望ましい。
【0030】
【発明の効果】
本発明の重合性高分子化合物は、重合性基を有するので、紫外線や電子線で短時間に硬化させることが可能であり、プラスチック基材との高密着性が期待でき、且つ硬度、染色性等に優れる反射防止膜等の光学用樹脂の原材料等として好適に利用することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a polymerizable polymer compound, a method for producing the same, and a synthetic intermediate polymer compound for producing the polymerizable polymer compound, and more specifically, can be cured in a short time with ultraviolet rays or an electron beam. A polymerizable polymer compound exhibiting a high refractive index that can be suitably used as a raw material for optical resins such as antireflection films that can be expected to have high adhesion to a plastic substrate and is excellent in hardness, dyeability, etc. , A production method thereof, and a synthetic intermediate polymer compound.
[0002]
[Prior art]
In recent years, plastic materials have been widely used as a substitute for glass by making use of characteristics such as impact resistance, light weight, easy moldability, and workability. However, since plastic materials have low surface hardness and are easily damaged, they are coated with various hard coating agents to improve scratch resistance (Japanese Patent Laid-Open Nos. 57-2735 and 59-204669). . On the other hand, a high refractive index (for example, a refractive index exceeding 1.60) is required for use as an optical multilayer film (selective reflection film, selective transmission film, etc.). However, there are few plastic materials having such a high refractive index, and high refractive index materials have problems of transparency and coloring, and are not suitable for practical use.
[0003]
Therefore, currently used optical multilayer films are produced by vapor deposition of inorganic materials. In such a production by vapor deposition, since it is difficult to increase the area and the cost is high, there is a potential market demand, but it has not yet been used for general purposes. Therefore, a plastic high refractive index material capable of forming a film by a simple coating method is desired.
[0004]
By the way, a monomer composition having a benzothiazole skeleton and a high refractive index resin obtained by polymerizing the composition (for example, JP-A-2-29401, JP-A-2-265907, JP-A-4-257531, Kaihei 4-225007, JP-A-4-300909), and plastic lens materials having a naphthalene skeleton and high refractive index resins (for example, JP-A-62-276501, JP-A-1-242608) Proposals have been made. However, none of the polymer compounds proposed in these prior arts have a polymerizable group, and no polymer compound that can be a highly refractive material having a polymerizable group is known.
[0005]
[Problems to be solved by the invention]
An object of the present invention is an optical resin such as an antireflection film that can be cured in a short time with ultraviolet rays or an electron beam, can be expected to have high adhesion to a plastic substrate, and is excellent in hardness, dyeability, etc. Another object of the present invention is to provide a polymerizable polymer compound exhibiting a high refractive index that can be suitably used as a raw material for the same and a method for producing the same.
Another object of the present invention is to provide a synthetic intermediate polymer compound that can be used for the production of the polymerizable polymer compound and can produce the polymerizable polymer compound with high production efficiency.
[0006]

DETAILED DESCRIPTION OF THE INVENTION
The polymerizable polymer compound of the present invention has repeating units represented by the general formulas (1) and (2). These repeating units may be arranged either randomly or in blocks. In the general formula (1), n is a positive number of 1 or more, and preferably a positive number of 1 to 5. In the general formula (2), m is a positive number of 1 or more, preferably a positive number of 1 to 5. In the general formulas (1) and (2), the halogen atom excluding the fluorine atom represented by X or Z is preferably a chlorine atom, a bromine atom or an iodine atom.
[0012]
The number average molecular weight of the polymerizable polymer compound of the present invention is 2,000 to 2,000,000, preferably 5,000 to 1,000,000. If it is less than 2,000, the form becomes liquid and purification is difficult, and if it exceeds 2,000,000, the solubility in a solvent is remarkably deteriorated. Moreover, the polymerizable polymer compound of the present invention exhibits a high refractive index, and usually exhibits a refractive index of 1.60 or more.
[0013]
The combination of the repeating units represented by the general formulas (1) and (2) is not particularly limited, and any combination may be used. Typically, preferred combinations of the respective examples of monomers constituting the repeating units represented by the general formulas (1) and (2) described later and combinations of the examples can be mentioned.
[0014]
In the polymerizable polymer compound of the present invention, the content ratio of each of the repeating units represented by the general formulas (1) and (2) is preferably 5 to 95:95 to 5 and particularly preferably 25 to 25 in terms of molar ratio. It is the range of 90: 75-10. When the content ratio of the repeating unit represented by the general formula (1) is less than 5 mol%, the ratio of the polymerizable group is not sufficient, and when it exceeds 95 mol%, the refractive index becomes low, which is not preferable. .
[0015]
