- the resin compositions obtained in Examples 1 to 13 have a relatively high glass transition temperature as well as an Abbe number in the intermediate region and a high refractive index. Further, in Examples 1 to 13, compared to Comparative Example 1, birefringence was also lowered. Further, in Examples 1 to 13, although the load was smaller than that in Comparative Example 1, the MFR value was increased and the fluidity was greatly improved as compared with Comparative Example 1.
- a composition containing a BNEF or BNF (particularly BNEF) unit is excellent in heat resistance.

- a composition containing BNEF units is excellent in the balance of various properties, has the highest heat resistance, and the highest fluidity, and is suitable for molding applications. Birefringence is also lower than the cyclic olefin resin (Comparative Example 1) that does not contain BNEF units.

Abstract
Description
前記式(1)において、基R1は水素原子又はメチル基、基R2は水素原子、基Wはカルボキシル基、C1-2アルコキシ-カルボニル基、シアノ基又はアミド基、qは0であってもよい。また、環状オレフィン系樹脂のガラス転移温度は、140~250℃程度であってもよい。
前記式(2)において、基Xが[(OR5)n1-Y1]のとき、置換基Y1はヒドロキシル基又はグリシジルオキシ基、環Zはベンゼン環、ナフタレン環又はビフェニル環(特にナフタレン環)、R3はC1-4アルキル基、kは0又は1、R4はC1-4アルキル基、C1-4アルコキシ基、mは0又は1、R5はC2-4アルキレン基、n1は0~2の整数、pは1又は2であってもよい。
環状オレフィン系樹脂は、官能基(A)を有している。環状オレフィン系樹脂は、環内にエチレン性二重結合を有する環状オレフィンを少なくとも重合成分とする樹脂(例えば、環状オレフィンの単独重合体、環状オレフィンと共重合性単量体との共重合体)であってもよい。なお、前記官能基(A)は、環状オレフィン及び/又は共重合性単量体に含まれていてもよく、好ましくは少なくとも環状オレフィンに含まれていてもよい。
置換基R1及びR2のアルキル基としては、例えば、メチル基、エチル基などのC1-4アルキル基などが挙げられる。置換基R2のアリール基としては、例えば、フェニル基などが挙げられる。R1は水素原子、メチル基が好ましく、R2は水素原子が好ましい。
なお、式(1a)で表される構成単位を有する共重合体は、交互共重合体、ランダム共重合体、ブロック共重合体などであってもよい。
フルオレン化合物は、9,9-ビスアリールフルオレン骨格及び極性置換基(B)を有している。この極性置換基(B)と、前記官能基(A)との組み合わせにより、フルオレン化合物と環状オレフィン系樹脂との相溶性(又は混和性)が向上すると推定され、有効にアッベ数を低減できる。
前記式(2)において、環Zで表されるアレーン環としては、ベンゼン環などの単環式アレーン環、多環式アレーン環などが挙げられ、多環式アレーン環には、縮合多環式アレーン環(縮合多環式炭化水素環)、環集合アレーン環(環集合芳香族炭化水素環)などが含まれる。
置換数mの数は、環Zの種類やmの数などに応じて適宜選択でき、例えば、0~8程度の整数であってもよく、0~4の整数、好ましくは0~3(例えば、0~2)の整数、特に0又は1であってもよい。特に、mが1又は2である場合、環Zがベンゼン環、ナフタレン環又はビフェニル環、置換基R4がメチル基であってもよい。
本発明の樹脂組成物は、官能基(A)を有する前記環状オレフィン系樹脂と、極性置換基(B)を有する前記フルオレン化合物とを含んでおり、前記フルオレン化合物の添加又は混合(又は溶融混練の)割合が少量であっても、環状オレフィン系樹脂のアッベ数を有効に低減可能であり、中間領域のアッベ数を有する樹脂組成物を得ることができる。また、環状オレフィン系樹脂(例えば、多環式オレフィン系樹脂)であっても、所定の官能基を有しているためか、極性基を有するフルオレン化合物との相溶性が高く、フルオレン化合物の割合が多くても、白濁することなく、均一に混和可能であり、大きくアッベ数を低減することができるとともに、透明性に優れている。また、このような環状オレフィン系樹脂は、前記官能基を有する剛直な架橋構造(例えば、ノルボルネン骨格を有する二環式構造、三環式構造など)を有しているため、ガラス転移温度が高く、フルオレン化合物を添加しても、高い耐熱性(ガラス転移温度)を維持できる。さらに、アッベ数の低減とともに、屈折率も有効に大きくできるため、中間領域のアッベ数であっても屈折率が高い。そのため、光学設計の自由度を向上でき、光学材料用途(例えば、光学レンズ、光学シート、光学フィルムなど)として利用できる。
試料をテトラヒドロフラン(THF)に溶解させ、ゲル浸透クロマトグラフィー(東ソー(株)製、HLC-8120GPC)を用いて、ポリスチレン換算で、重量平均分子量(Mw)を測定した。
