Description
本発明は卓越した接着性、高温安定性、機械的強度及び成型性を有する高制動性ポリマーに関する。
特徴の望ましい組み合わせを潜在的に提供する製品を得るための広範な種類のランダムなもしくは構造をもつ形態を形成するために、2種以上のポリマーを一緒に混合することができる。しかし、単純な混合により多数の可能な組み合わせを達成することは実際には困難もしくは不可能ですらあるかも知れない。ポリマーはしばしば熱動力学的に非混和性であり、それが真に均質の製品を生成することを妨げる。2相構造を有することが所望される可能性があるので、非混和性は問題ではないかも知れないが、これら2相間の界面における状態が問題に導くことが極めて多い。典型的な事例は2相間の高い界面張力及び低い接着性である。この界面張力は高い粘性と共に、ランダムな混合物に対する所望の分散度の付与の固有の困難及びそれらのその後の安定性の欠如の原因であり、後の加工もしくは使用中の著しい分離もしくは層状化をもたらす。弱い接着性は、部分的に、分散混合物に認めることが多い極めて弱く、脆い機械的動態に導くことがあり、幾つかの高度に構造的な形態を不可能にする可能性がある。
本発明は無水物及びアルケニル単位を含むポリマー、架橋剤、マレイン化ポリアルキレン、増量材、並びにエポキシを含むポリマーゲル組成物を提供する。ポリマーゲルはグラフト化剤とポリマー成分を反応させ、次いでエポキシポリマーと混合することにより生成させることができる。
本発明の代表的なポリマーゲル組成物はジアミングラフト化剤との架橋反応により生成した少なくとも1個の官能結合によりそれにグラフト重合された少なくとも1個のマレイン化ポリアルキレンセグメントを有する0.5〜200重量部のポリ(アルケニル−co−マレイミド)並びに1000重量部までの超分岐エポキシポリマーを含有する。一般的な用語のポリ(アルケニル−co−マレイミド)はポリ(アルケニルベンゼン−co−マレイミド)、ポリ(R1R2エチレン−co−マレイミド)及びポリ(アルキルビニルエーテル−co−マレイミド)のような群を含む。
実施例1に対しては、ポリ[(o−クレジルグリシジルエーテル)−co−ホルムアルデヒド](Mn〜1080)35.0gをトルエン50mLに溶解した。ドデシルアミン4.3g、次いでジブチルアミン23.0gを添加した。混合物を100℃〜150℃で6時間反応させた。次いで生成物を1時間、200℃に加熱して揮発物を追い出した。
(実施例5) PP−グラフト化ムカデ状ポリマーの製造
シグマブレードの付いた6Lの混練−押し出し機(MXE−6、Jaygo Inc.)に、IsobanTM10のポリ(無水マレイン酸−alt−イソブチレン)(Kuraray Ltd.)1.25kg及びオクチルアミン(BASF、99%純度)0.99kgを54℃で添加した。25rpmのブレード速度、5分間40rpmのスクリュー速度で混合を開始し、次いでミキサマの温度を約3℃/分の速度で190℃まで上昇するように調整した。混合を190℃で更に2時間、等温で継続した。
(実施例6〜12) 高制動性ゲルの製造
実施例6〜8に対しては、実施例5からの生成物35gの充填をローラーブレード及びN2パージを伴ったブラベンダーミキサー(〜559容量)に加えた。ミキサーを最初は160℃及び60rpmに設定した。3分後、実施例1からの生成物15gの充填をミキサーに加えた。物質を更に17分間これらの条件下で混合し、次いで撹拌を停止し、混合物をミキサーから取り出した。
