Abstract
Description
一般式(1)において、mが0であることが好ましい。
一般式(1)において、R1〜R4が、水素原子または炭素数1〜3のアルキル基であることが好ましい。
単環の環状オレフィンが、シクロペンテン、シクロヘキセン、シクロヘプテンおよびシクロオクテンからなる群より選択される少なくとも1種であることが好ましい。
本発明のゴム組成物は、架橋剤をさらに含有することが好ましい。
本発明の開環共重合体は、下記一般式(1)で表されるノルボルネン化合物由来の構造単位、および、単環の環状オレフィン由来の構造単位を含む。
3−メトキシカルボニル−5−ノルボルネン−2−カルボン酸などのアルコキシカルボニル基とヒドロキシカルボニル基とを有するビシクロ[2.2.1]ヘプト−2−エン類;
本発明の開環共重合体を製造する方法は特に限定されないが、たとえば、上記一般式(1)で表されるノルボルネン化合物と、単環の環状オレフィンとを、開環重合触媒の存在下で共重合させる方法が挙げられる。
本発明のゴム組成物には、上述した本発明の開環共重合体に、常法に従って、架橋剤、架橋促進剤、架橋活性化剤、シリカ以外の充填剤、老化防止剤、活性剤、プロセス油、可塑剤、滑剤などの配合剤をそれぞれ必要量配合できる。
本発明のゴム架橋物は、上述した本発明のゴム組成物を架橋してなるものである。
本発明のゴム架橋物は、本発明のゴム組成物を用い、たとえば、所望の形状に対応した成形機、たとえば、押出機、射出成形機、圧縮機、ロールなどにより成形を行い、加熱することにより架橋反応を行い、架橋物として形状を固定化することにより製造することができる。この場合においては、予め成形した後に架橋しても、成形と同時に架橋を行ってもよい。成形温度は、通常、10〜200℃、好ましくは25〜120℃である。架橋温度は、通常、100〜200℃、好ましくは130〜190℃であり、架橋時間は、通常、1分〜24時間、好ましくは2分〜12時間、特に好ましくは3分〜6時間である。
テトラヒドロフランを溶媒とするゲルパーミエーション・クロマトグラフィー(GPC)により、開環共重合体の数平均分子量(Mn)、重量平均分子量(Mw)および分子量分布(Mw/Mn)を、ポリスチレン換算値として測定した。測定装置としてHLC−8320GPC(東ソー社製)を用いた。測定は、TSKgelSuperMultiporeHZ−H(東ソー社製)を4本直列に繋いだカラムを用い、流速0.35ml/分、サンプル注入量10μml、カラム温度40℃の条件で行った。
開環共重合体中の単量体組成比を、1H−NMRスペクトル測定から求めた。すなわち、重クロロホルムを溶媒として、1H−NMR測定を行い、二重結合由来の5.0〜5.5ppmのシグナルの積分比と、ノルボルネン化合物由来の2.3〜3.0ppmのシグナルの積分比に基づいて決定した。
開環共重合体の主鎖二重結合のシス/トランス比を、13C−NMRスペクトル測定から求めた。すなわち、重クロロホルムを溶媒として、13C−NMR測定を行い、シスを示す134.0ppm付近(ノルボルネン化合物単位連鎖由来)、130.0ppm付近(単環の環状オレフィン構造単位連鎖由来)、135.4ppm付近(ノルボルネン化合物構造単位/単環の環状オレフィン構造単位の交互連鎖由来)のシグナルの積分比 と、トランスを示す133.0ppm付近(ノルボルネン化合物単位連鎖由来)、130.5ppm付近(単環の環状オレフィン構造単位連鎖由来)、128.4ppm付近(ノルボルネン化合物構造単位/単環の環状オレフィン構造単位の交互連鎖由来)のシグナルの積分比 から求めた。
開環共重合体のガラス転移温度(Tg)を、示差走査熱量計(DSC)を用いて、10℃/分の昇温で測定した。
試料となるゴム組成物を160℃で20分間プレス架橋して試験片を作製し、得られた架橋物シートを、列理方向に対して平行方向に、ダンベル状6号形に打ち抜くことで、ダンベル状試験片を得た。そして、得られたダンベル状試験片について、試験機として引張試験機(製品名「TENSOMETER10K」、ALPHA TECHNOLOGIES社製、ロードセル式 1kN)を使用し、JIS K6251:2010に準拠して、23℃、500mm/分の条件にて、引張試験を行い、引張強度と切断時伸び(以下、伸びという)を測定した。
試料となるゴム組成物を、金型を用いて、加圧しながら160℃で、25分間プレス成形して、直径29mm、厚さ12.5mmの円柱状のゴム架橋物を得た。そして、得られた円柱状のゴム架橋物について、試験機としてリュプケ式反発弾性試験機(高分子計器社製)を使用して、JIS K6255:1996に準拠して、23℃、保持力:29〜39Nの条件にて、反発弾性率を測定した。
窒素雰囲気下、攪拌機を備えたガラス反応容器に、ノルボルネン化合物として2−ノルボルネン(NB)100部、単環の環状オレフィンとしてシクロペンテン(CPE)100部、トルエン394部および1−ヘキセン0.24部を加えた。次に、トルエン10部に溶解したジクロロ−(3−フェニル−1H−インデン−1−イリデン)ビス(トリシクロヘキシルホスフィン)ルテニウム(II)0.012部を加え、室温で4時間重合反応を行った。重合反応後、過剰のビニルエチルエーテルを加えることにより重合を停止した。
ノルボルネン化合物として2−ノルボルネン120部、単環の環状オレフィンとしてシクロオクテン(COE)80部とし、1−ヘキセン0.34部とした以外は実施例1と同様にして、開環共重合体194部を得た。得られた開環共重合体の数平均分子量(Mn)は103,000、重量平均分子量(Mw)は249,000で、2−ノルボルネン構造単位/シクロオクテン構造単位比は59/41(重量比)、シス/トランス比は18/82、ガラス転移温度(Tg)は−32℃であった。
