Description
本発明は、環状オレフィン系ポリマーの製造方法に関するものである。 The present invention relates to a method for producing a cyclic olefin polymer.
従来の環状オレフィン系ポリマーの製造方法においては、遷移金属触媒を用いて、ノルボルネン系付加重合体を製造する方法が知られている(例えば、特許文献1参照。)。
環状オレフィン系ポリマーは、各種用途に応じた分子量に制御して用いられることが多い。分子量制御の方法としては、特許文献2に例示されているように種々の方法が知られている。しかしながら、分子量調整剤としてα−オレフィンやシクロペンテン誘導体を用いた場合には、生成ポリマー中に残るポリマー末端の二重結合が目的用途によってはポリマーの酸化劣化の原因となるなどの恐れがあった。また、2種類以上の環状オレフィンモノマーを重合する場合には、各環状オレフィン系モノマーの反応性の違いにより、共重合体組成比を正確に制御することが困難であった。
As a conventional method for producing a cyclic olefin polymer, a method for producing a norbornene addition polymer using a transition metal catalyst is known (for example, see Patent Document 1).
Cyclic olefin polymers are often used in a controlled molecular weight according to various applications. As a method for controlling the molecular weight, various methods are known as exemplified in Patent Document 2. However, when an α-olefin or a cyclopentene derivative is used as a molecular weight modifier, there is a risk that the polymer terminal double bond remaining in the produced polymer may cause oxidative degradation of the polymer depending on the intended use. When two or more kinds of cyclic olefin monomers are polymerized, it is difficult to accurately control the copolymer composition ratio due to the difference in reactivity of each cyclic olefin monomer.
一方、イオン液体は、広い温度範囲において液体である塩または塩の混合物で、環境に優しい溶剤としてグリーンケミストリーなどの分野で注目されている。例えば、特許文献3には、イオン液体存在下での遷移金属触媒を用いたメタセシス反応において、イオン液体と触媒を含む相は更なるメタセシス反応にも使用できることが記載されている。また、特許文献4には、ある種のイオン液体存在下でのフリーラジカル重合において、多分散指数(PDI)の低いポリマーが得られた例が記載されている。しかしながら、イオン液体を用いた分子量や共重合体比が制御された環状ポリオレフィン系ポリマーの効率的な製造方法は見出されていない。 On the other hand, an ionic liquid is a salt or a mixture of salts that are liquid in a wide temperature range, and has attracted attention in the field of green chemistry as an environmentally friendly solvent. For example, Patent Document 3 describes that in a metathesis reaction using a transition metal catalyst in the presence of an ionic liquid, the phase containing the ionic liquid and the catalyst can be used for further metathesis reactions. Patent Document 4 describes an example in which a polymer having a low polydispersity index (PDI) is obtained in free radical polymerization in the presence of a certain ionic liquid. However, an efficient method for producing a cyclic polyolefin polymer in which the molecular weight and copolymer ratio using an ionic liquid are controlled has not been found.
本発明の目的は、分子量および分子量分布が制御され、かつ2種以上のモノマーを重合する場合にはその共重合比の制御されたポリマーを製造するための環状オレフィン系ポリマーの製造方法を提供するものである。 An object of the present invention is to provide a method for producing a cyclic olefin-based polymer for producing a polymer having a controlled molecular weight and molecular weight distribution and a controlled copolymerization ratio when two or more monomers are polymerized. Is.

本発明の環状オレフィン系ポリマーを製造する方法について、その例を詳細に説明する。
まず、1種以上の任意の環状オレフィンモノマーに、前記イオン液体に溶解した前記触媒および任意に前記助触媒を所定の量で添加する。この混合溶液を、加熱装置を備えた反応装置に入れて、加熱しながら撹拌し、反応させて付加重合することにより、環状オレフィン系ポリマーを製造することができる。また、製造においては、例えば、重合温度、イオン液体の種類、及びイオン液体の量などを適宜調節することにより、所望の分子量を得ることができる。
Examples of the method for producing the cyclic olefin polymer of the present invention will be described in detail.
First, a predetermined amount of the catalyst dissolved in the ionic liquid and optionally the promoter is added to one or more arbitrary cyclic olefin monomers. A cyclic olefin-based polymer can be produced by placing this mixed solution in a reaction apparatus equipped with a heating apparatus, stirring while heating, reacting, and addition polymerization. In production, for example, a desired molecular weight can be obtained by appropriately adjusting the polymerization temperature, the type of ionic liquid, the amount of ionic liquid, and the like.
環状オレフィンモノマーの付加重合における加熱方法としては、温度を精密に制御できるものであれば、特に限定されないが、例えば、マイクロ波反応装置を用いたマイクロ波照射による加熱、オイルバスおよび電熱ヒーター等による一般的な加熱などが挙げられ、これらの方法は併用することができる。前記環状オレフィン系ポリマーを高分子構造とするために、前記反応領域における温度は、50℃〜300℃が好ましく、より好ましくは60℃〜250℃である。また反応温度を変更することによって、環状オレフィン系ポリマーの分子量を制御できる。一方、反応時間は、5分〜20時間が好ましく、さらに好ましくは30分〜12時間、もっとも好ましくは1時間〜6時間であるが、マイクロ波を照射して重合する場合は、短時間で反応が進行するためこの限りではなく、この場合は、5秒〜20時間が好ましく、より好ましくは、10秒〜6時間である。反応中の雰囲気として、通常、窒素流通下、開放系で反応を行うが、揮発性のあるモノマーを使用する際は、ガラス製等の耐圧容器を用いて密閉系で反応を行ってもよい。 The heating method in the addition polymerization of the cyclic olefin monomer is not particularly limited as long as the temperature can be precisely controlled. For example, heating by microwave irradiation using a microwave reactor, oil bath, electric heater, etc. General heating etc. are mentioned, These methods can be used together. In order to make the cyclic olefin polymer have a high molecular structure, the temperature in the reaction region is preferably 50 ° C to 300 ° C, more preferably 60 ° C to 250 ° C. Further, the molecular weight of the cyclic olefin polymer can be controlled by changing the reaction temperature. On the other hand, the reaction time is preferably from 5 minutes to 20 hours, more preferably from 30 minutes to 12 hours, most preferably from 1 hour to 6 hours. In this case, 5 seconds to 20 hours are preferable, and 10 seconds to 6 hours are more preferable. As an atmosphere during the reaction, the reaction is usually performed in an open system under a nitrogen flow. However, when a volatile monomer is used, the reaction may be performed in a closed system using a pressure vessel made of glass or the like.
マイクロ波照射を用いた環状オレフィンモノマーの重合におけるマイクロ波の照射方法としては、環状オレフィンモノマーの反応を促進できるものであれば特に限定されないが、照射するマイクロ波の周波数範囲が2450〜2455MHzであることが好ましい。2450〜2455MHzのマイクロ波を照射することにより、一般的な加熱のみによる重合と比較して、短時間・低触媒量で、反応物中の環状オレフィンモノマーを重合化することができる。
前記マイクロ波照射におけるマイクロ波を照射するモードとしては、例えば、出力制御モード、温度制御モード及び圧力制御モード等を用いることができるが、これらの中でも、マイクロ波を高出力で照射することが可能となるため、温度制御モードが好ましい。さらに、温度制御モードにおいて、マイクロ波出力はできる限り大きい方が好ましいが、例えば、10W以上、5,000W以下であることが好ましい。これにより前記混合物の昇温効率を向上させることができる。
本発明において、環状オレフィンモノマーの付加重合を効率よく進行させる点から、加熱及びマイクロ波照射を併用することが好ましい。
The microwave irradiation method in the polymerization of the cyclic olefin monomer using microwave irradiation is not particularly limited as long as it can accelerate the reaction of the cyclic olefin monomer, but the frequency range of the irradiated microwave is 2450 to 2455 MHz. It is preferable. By irradiating microwaves of 2450 to 2455 MHz, the cyclic olefin monomer in the reaction product can be polymerized in a short time and with a low catalyst amount as compared with polymerization by general heating alone.
As the microwave irradiation mode in the microwave irradiation, for example, an output control mode, a temperature control mode, a pressure control mode, and the like can be used. Among these, a microwave can be irradiated at a high output. Therefore, the temperature control mode is preferable. Furthermore, in the temperature control mode, it is preferable that the microwave output is as large as possible, but it is preferably 10 W or more and 5,000 W or less, for example. Thereby, the temperature rising efficiency of the mixture can be improved.

本発明により得られる環状オレフィン系ポリマーは、従来のように連鎖移動剤等を用いることなく、分子量を制御することができる。例えば、成形加工性等の特性を得る上で、制御される環状オレフィン系ポリマーの重量平均分子量は、50,000〜150,000が好ましく、より好ましくは75,000〜120,000である。また、スピンコート法等により、環状オレフィン系ポリマーを薄膜にして試用する必要がある場合等にはより低い重量平均分子量であることが望ましい。この場合の環状オレフィン系ポリマーの重量平均分子量は、1,000〜50,000が好ましく、より好ましくは2,000〜40,000である。
本発明において、重量平均分子量は標準ポリスチレンを用いて、ゲルパーミエーションクロマトグラフィー(GPC)を用いて測定することができる。
The cyclic olefin polymer obtained by the present invention can control the molecular weight without using a chain transfer agent or the like as in the prior art. For example, the weight average molecular weight of the cyclic olefin polymer to be controlled is preferably 50,000 to 150,000, and more preferably 75,000 to 120,000 for obtaining properties such as moldability. Further, when it is necessary to use a cyclic olefin polymer as a thin film by spin coating or the like, a lower weight average molecular weight is desirable. In this case, the weight average molecular weight of the cyclic olefin polymer is preferably 1,000 to 50,000, more preferably 2,000 to 40,000.
In the present invention, the weight average molecular weight can be measured by gel permeation chromatography (GPC) using standard polystyrene.
前記環状オレフィン系ポリマーの分子量分布[重量平均分子量:Mwと、数平均分子量:Mnとの比(Mw/Mn)]は、特に限定されないが、1.0以上2.5以下の比較的小さい範囲の分子量分布を得ることができる。また、前記同様に成形加工性等の特性を得る上では、1.0以上3.5以下が好ましく、1.2以上3.0以下とすることがより好ましく、1.5以上2.5以下とすることがさらに好ましい。
前記分子量分布を測定する方法としては、例えばシクロヘキサン又はテトラヒドロフランを有機溶剤とするGPCで測定することができる。
The molecular weight distribution of the cyclic olefin-based polymer [the ratio of weight average molecular weight: Mw and number average molecular weight: Mn (Mw / Mn)] is not particularly limited, but is a relatively small range of 1.0 to 2.5. The molecular weight distribution can be obtained. Further, in the same manner as described above, in order to obtain characteristics such as moldability, 1.0 or more and 3.5 or less are preferable, 1.2 or more and 3.0 or less are more preferable, and 1.5 or more and 2.5 or less More preferably.
As a method for measuring the molecular weight distribution, for example, it can be measured by GPC using cyclohexane or tetrahydrofuran as an organic solvent.
また、上記方法で重量平均分子量や分子量分布が測定できない環状オレフィン系ポリマーの場合には、通常の溶融加工法により、樹脂層を形成し得る程度の溶融粘度や重合度を有するものを使用することができる。前記環状オレフィン系ポリマーガラス転移温度は、使用目的に応じて適宜選択できるが、通常50℃以上、好ましくは70℃以上、より好ましくは100℃以上、さらに好ましくは125℃以上のポリマーを得ることができる。 In the case of a cyclic olefin polymer whose weight average molecular weight or molecular weight distribution cannot be measured by the above method, use a polymer having a melt viscosity and a degree of polymerization that can form a resin layer by an ordinary melt processing method. Can do. The cyclic olefin-based polymer glass transition temperature can be appropriately selected depending on the purpose of use, but it is usually 50 ° C. or higher, preferably 70 ° C. or higher, more preferably 100 ° C. or higher, more preferably 125 ° C. or higher. it can.
また、環状オレフィン系ポリマーの製造において、2種類以上の環状オレフィンモノマーを用いて重合した場合、個々のモノマーの共重合反応性に前記環状オレフィンポリマーの共重合比は影響を受けるため、共重合比を制御するために、従来法において、一般的には、共重合反応性の低いモノマーを過剰に仕込む方式や逐次添加する方式が採られていたが、これらの方式では、未反応モノマーが多く残るといった欠点があった。本発明では、従来のように、共重合反応性に左右されることなく、仕込み比に近い値に共重合比を制御することができる。共重合におけるモノマーの組合せとしては、炭化水素基を有するモノマーと極性基を有するモノマー、異なる炭化水素基を有するモノマー同士、異なる極性基を有するモノマー同士が挙げられ、これらの組合せに制限はないが、例えば、5−ヘキシル−2−ノルボルネンと5−ジフェニルメチルシリルメチルエーテル−2−ノルボルネンなどの共重合において、その効果が発現される。 In addition, in the production of a cyclic olefin polymer, when two or more kinds of cyclic olefin monomers are used for polymerization, the copolymerization ratio of the cyclic olefin polymer is affected by the copolymerization reactivity of each monomer. In order to control the above, in the conventional method, generally, a method in which a monomer having low copolymerization reactivity is excessively charged or a method in which it is sequentially added has been adopted, but in these methods, a large amount of unreacted monomer remains. There was a drawback. In the present invention, the copolymerization ratio can be controlled to a value close to the charging ratio without depending on the copolymerization reactivity as in the prior art. Examples of the monomer combination in the copolymerization include a monomer having a hydrocarbon group and a monomer having a polar group, monomers having different hydrocarbon groups, and monomers having different polar groups, and these combinations are not limited. For example, the effect is expressed in copolymerization of 5-hexyl-2-norbornene and 5-diphenylmethylsilylmethyl ether-2-norbornene.
