Abstract
Description
ノルボルネンなどの環状オレフィンの重合体は一般に耐熱性に優れるが、耐熱性を一層向上させるノルボルネン系架橋重合体の製造技術として、例えば、極性基を有する所定のノルボルネン系モノマーを用いる方法(特許文献1)や、所定のメタセシス触媒を用いる方法(特許文献2)が提案されている。しかしながら、得られる重合体の耐熱性については未だ改良の余地があった。
〔1〕ジシクロペンタジエン系単量体単位、テトラシクロドデセン系単量体単位及びトリシクロペンタジエン系単量体単位からなる群から選択される少なくとも1種を50質量%以上含有してなり、ガラス転移温度が240℃以上であるノルボルネン系架橋重合体;並びに
〔2〕ジシクロペンタジエン系単量体、テトラシクロドデセン系単量体及びトリシクロペンタジエン系単量体からなる群から選択される少なくとも1種と、メタセシス重合触媒と、を含有してなる配合物を、前記メタセシス重合触媒の失活温度未満の温度で加熱して一次硬化させる工程(1)、並びに
工程(1)により得られた硬化物を前記メタセシス重合触媒の失活温度以上の温度で加熱して二次硬化させる工程(2)
を含む、前記〔1〕に記載のノルボルネン系架橋重合体の製造方法、に関するものである。
更に、これらの単量体は、置換基として、水酸基、エステル基(−C(O)O−)、エーテル基(−O−)、エポキシ基、シアノ基、ハロゲン原子等の極性基を有していてもよい。
特に、用いる単量体が、水酸基、エポキシ基およびシアノ基などの極性基を有すると、本発明のノルボルネン系架橋重合体を、例えば、パワー半導体などの封止材料として用いる場合、封止対象である半導体素子との密着性が向上し、絶縁性能が充分に発揮されるため好適である。
以上の単量体は、それぞれ単独であるいは2種以上を組み合わせて用いられる。
本発明のノルボルネン系架橋重合体としては中でも、耐熱性と絶縁性とをバランス良く向上させる観点から、トリシクロペンタジエン系単量体単位を、50質量%以上含有してなるものが好ましく、60〜100質量%含有してなるものがより好ましく、70〜100質量%含有してなるものが特に好ましい。
本発明のノルボルネン系架橋重合体は、例えば、後述する製造方法により製造されるが、重合反応の際に気泡が発生し、得られる重合体中に気泡が含まれることがある。重合体中に気泡が存在すると、その絶縁性が低下する。意外にも、トリシクロペンタジエン系単量体を多く含む配合物を用いて重合反応を行った場合、気泡の発生が抑制され、そのようにして得られる重合体の中でも、特にトリシクロペンタジエン系単量体単位を上記範囲で含有する、本発明のノルボルネン系架橋重合体には気泡が実質的に含まれないことから、耐熱性と絶縁性とがバランス良く向上するものと推定される。
なお、1分間耐電圧は後述の実施例に記載の方法により求めることができる。
配合物中のラジカル発生剤の配合量としては、通常、用いる全単量体成分100質量部に対して、0.5〜2.0質量部である。
なお、いずれの方法においても、冷却固化する際の冷却温度としては、用いる単量体成分にもよるが、通常、−60〜0℃が好ましい。
支持体としては、例えば、ポリエチレンテレフタレート、ポリプロピレン、ポリエチレン、ポリカーボネート、ポリエチレンナフタレート、ポリアリレート、及びナイロンなどの樹脂からなるフィルムや板;鉄、ステンレス、銅、アルミニウム、ニッケル、クロム、金、銀などの金属材料からなるフィルムや板;などが挙げられる。なかでも、樹脂フィルム又は金属箔の使用が好ましい。これら樹脂フィルム又は金属箔の厚さは、作業性などの観点から、通常、1〜150μm、好ましくは2〜100μm、より好ましくは3〜75μmである。
本方法においては、用いるメタセシス重合触媒が活性剤(共触媒)を必要とするものであるか否かにより、以下の2つの方法により、配合物の調製を行うのが好ましい。
工程(2)における硬化物の加熱は、使用したメタセシス重合触媒の失活温度よりも、好ましくは60℃高い温度、より好ましくは70℃高い温度、さらに好ましくは80℃高い温度で行う。工程(2)における加熱温度の具体的な温度範囲としては、通常、250℃以上、350℃未満、好ましく280〜330℃、より好ましくは300〜310℃である。
また、工程(2)における硬化物の加熱時間としては、通常、10〜120分間、好ましくは20〜90分間、より好ましくは30〜60分間である。

メタセシス重合触媒として、下記式(7)で示すルテニウム触媒(VC843、分子量843、Strem Chemicals社製)0.6部、及び2,6−ジ−t−ブチル−p−クレゾール(BHT、老化防止剤)15部をシクロペンタノン82部に溶解させ、次いで、3,4−ジメチルピリジン2.2部、及びフェニルトリクロロシラン0.1部を混合することで、触媒液を得た。
