Description
本発明は、透明性、高耐熱性、および有機溶媒への高い溶解性を兼ね備え、複屈折の大きさや波長依存性を特定の置換基によりコントロールすることができる、ノルボルネン系樹脂とその製造方法に関する。 The present invention relates to a norbornene-based resin having both transparency, high heat resistance, and high solubility in an organic solvent, and capable of controlling the size and wavelength dependency of birefringence with a specific substituent, and a method for producing the same. .
従来、透明樹脂は自動車部品、照明機器、電気部品など通常の透明性が要求される材料として用いられ、特に最近では、光学的性質が重視される光学材料としての応用が進みつつある。このような用途に好適に用いられる透明樹脂としては、ポリカーボネート系樹脂やアクリル系樹脂が知られている。しかし、アクリル系樹脂は透明性に優れているが、耐熱性や耐水性等の点で問題がある。一方、ポリカーボネート系樹脂は、耐熱性や耐水性においてはアクリル系樹脂より優れているが、複屈折が高いなどの問題がある。このため、最近では、透明性、耐水性(低吸水性)、低複屈折性、耐熱性などを兼ね備えている環状オレフィン系樹脂が光学材料用の透明樹脂として用いられ注目されている。このような技術としてはたとえば特許文献1〜6などが挙げられる。 Conventionally, transparent resins have been used as materials that require normal transparency, such as automobile parts, lighting equipment, and electrical parts, and in particular, recently, applications as optical materials where optical properties are important are being advanced. As transparent resins suitably used for such applications, polycarbonate resins and acrylic resins are known. However, acrylic resins are excellent in transparency, but have problems in terms of heat resistance and water resistance. On the other hand, polycarbonate resins are superior to acrylic resins in heat resistance and water resistance, but have problems such as high birefringence. For this reason, recently, a cyclic olefin-based resin having transparency, water resistance (low water absorption), low birefringence, heat resistance and the like has been used as a transparent resin for optical materials. Examples of such a technique include Patent Documents 1-6.
しかしながら、光学機器の機能や用途の高度化に伴い、これらの従来公知の環状オレフィン系樹脂でも、光学材料に求められる特性を十分に満たせない場合が生じてきている。特に、高度化した機能を有する光学機器においては、十分な低複屈折性が非常に重要な物性であり、より優れた低複屈折性を有する透明樹脂の開発が望まれている。 However, with the advancement of functions and applications of optical devices, there are cases where even these conventionally known cyclic olefin resins cannot sufficiently satisfy the characteristics required for optical materials. In particular, in an optical apparatus having an advanced function, sufficient low birefringence is a very important physical property, and development of a transparent resin having a better low birefringence is desired.
一方、特に最近注目されている光学用フィルム用の樹脂としてみても、上記特性は前記従来の樹脂の問題点を改善できるものであり、このため、環状オレフィン系樹脂からなるフィルムが光学用の各種フィルムとして提案されている。例えば、特許文献7〜10には、環状オレフィン系樹脂のフィルムからなる位相差板が記載されている。また、特許文献11〜13には、環状オレフィン系樹脂のフィルムを偏光板の保護フィルムに使用することが記載されている。さらに、特許文献14には、環状オレフィン系樹脂のフィルムからなる液晶表示素子用基板が記載されている。しかしながら、従来の環状オレフィン系樹脂からなる光学用フィルムは、延伸配向させて得られる透過光に位相差(複屈折)を与える機能が、透過光の波長が長波長になるにつれて透過光の位相差(複屈折)の絶対値が小さくなるという特性を有するため、可視光領域(400〜800nm)全てにおいて、例えば1/4波長等の特定の位相差を透過光に与えることが非常に困難であった。こうした事情は、従来の環状オレフィン系樹脂のみならず、他の樹脂からなる光学用フィルムでも同様であった。 On the other hand, the above-mentioned characteristics can improve the problems of the conventional resins, even when viewed as a resin for optical films that has attracted particular attention recently. For this reason, films made of cyclic olefin resins can be used in various optical applications. Proposed as a film. For example, Patent Documents 7 to 10 describe a retardation plate made of a cyclic olefin resin film. Patent Documents 11 to 13 describe that a film of a cyclic olefin resin is used as a protective film for a polarizing plate. Furthermore, Patent Document 14 describes a substrate for a liquid crystal display element made of a film of a cyclic olefin resin. However, the conventional optical film made of a cyclic olefin resin has a function of giving a phase difference (birefringence) to transmitted light obtained by stretching and orientation, and the phase difference of transmitted light becomes longer as the wavelength of transmitted light becomes longer. Since the absolute value of (birefringence) is small, it is very difficult to give the transmitted light a specific phase difference such as a quarter wavelength in all the visible light region (400 to 800 nm). It was. This situation was the same not only for conventional cyclic olefin resins but also for optical films made of other resins.
上記に示す高度な光学用途に用いる樹脂は、一般的な光学特性のほかに複屈折の波長依存性、大きさをいかにコントロールするかが大きな課題である。 Resins used for the above-mentioned advanced optical applications have a major problem of how to control the wavelength dependence and size of birefringence in addition to general optical characteristics.
本発明は、上記課題を達成すべく成されたものであり、鋭意検討した結果、特定のノルボルネン系開環重合体及びその水素添加物は、重合組成比および置換基を選定することにより複屈折の大きさおよび波長依存性をコントロールすることができ、複屈折の特異な波長依存性(長波長になるに従い複屈折が大きくなる)、低複屈折性かつ透明性、非常に高い耐熱性を有することを見出し、本発明を完成するに至った。

Comparative Example 1
As norbornene monomer represented by the following structural formula C 8- methoxycarbonyl-8-methyl-tetracyclo [4.4.0.1 2, 5. 1 7,10 ] -3-dodecene (50 g), 1-hexene (3.6 g) and toluene (100 g) were charged into a nitrogen-substituted reaction vessel and heated to 80 ° C. To this was added 0.09 ml of a toluene solution of triethylaluminum (0.6 mol / L) and 0.29 ml of a methanol-modified WCl6 toluene solution (0.025 mol / L) and reacted at 80 ° C. for 3 hours to obtain a polymer. Obtained. Next, a hydrogenation reaction was performed in the same manner as in Example 1 to obtain a polymer hydrogenated product. The obtained hydrogenated product had a glass transition temperature (Tg) = 167 ° C., a weight average molecular weight (Mw) = 56000, and a molecular weight distribution (Mw / Mn) = 3.2. Further, the hydrogenation rate of this hydrogenated product by NMR measurement was 99.0% or more.

With respect to the obtained hydrogenated product, retardation (Re, retardation) was measured in the same manner as in Example 1, and birefringence was evaluated from the thickness (d) of the film. Table 1 shows the results of birefringence (Re550 / d = Δn550) at a measurement wavelength of 550 nm. Further, the wavelength dependency of retardation (Re) was evaluated in the same manner as in the Examples. Table 1 shows the measurement results of the retardation (Re) at each wavelength and the retardation (Re550) ratio at 550 nm.
この結果より、比較例1に比べ実施例1では複屈折が低いことがわかった。また、比較例1で得られた水素添加物では、測定波長に対して依存性が小さく、短波長側で若干大きくなるが、実施例1で得られた水素添加物では、長波長側になるに従いレターデーション比が大きくなることがわかった。 From this result, it was found that the birefringence was lower in Example 1 than in Comparative Example 1. The hydrogenated product obtained in Comparative Example 1 is less dependent on the measurement wavelength and slightly increases on the short wavelength side, whereas the hydrogenated product obtained in Example 1 is on the long wavelength side. It was found that the retardation ratio increased according to the results.
