Abstract
Description
本発明は、オレフィンブロック共重合体およびその重合方法に関する。 The present invention relates to an olefin block copolymer and a polymerization method thereof.
異なるセグメントが結合したブロック共重合体は、種々の有用な物性を示すことから、学術的見地のみならず、工業的見地からも非常に重要である。 Since the block copolymer in which different segments are bonded exhibits various useful physical properties, it is very important not only from an academic viewpoint but also from an industrial viewpoint.
そしてこのような特定の構造を有する重合体の製造方法として重合中に停止反応および連鎖移動反応が実質的に起きないリビング重合が有効な方法であることは一般に良く知られている。 As a method for producing a polymer having such a specific structure, it is generally well known that living polymerization in which a termination reaction and a chain transfer reaction do not substantially occur during polymerization is an effective method.
しかし上記のような特定の構造を有する重合体を製造する際に、オレフィン重合触媒として一般的なZieglar触媒やメタロセン触媒を用いて通常の条件で重合を行うと、成長するポリマー鎖の連鎖移動反応が頻発するため、リビング重合でオレフィン重合体を製造することは非常に困難であった。例えば既知の触媒系を用いてブロック共重合体などを合成しようとすると、ホモおよびランダムコポリマーの混合物が生成することが、分子量分布、組成分布などの解析により明らかにされている(Boor,「Zieglar−Natta Catalyst and Polymerization」、Academic Press社、1979年)。 However, when a polymer having a specific structure as described above is produced, if polymerization is carried out under ordinary conditions using a general Zieglar catalyst or a metallocene catalyst as an olefin polymerization catalyst, a chain transfer reaction of the growing polymer chain Therefore, it is very difficult to produce an olefin polymer by living polymerization. For example, when a block copolymer or the like is synthesized using a known catalyst system, a mixture of homo and random copolymers is formed by analysis of molecular weight distribution, composition distribution, etc. (Boor, “Zieglar”). -Nata Catalyst and Polymerization ", Academic Press, 1979).
このような状況のもと、オレフィン類のブロック共重合を検討した例がいくつか報告されている。 Under such circumstances, several examples of studying block copolymerization of olefins have been reported.
例えば特定のメタロセン触媒を用いる方法が提案されている(国際公開WO91/12285号、WO94/21700号など参照)。これらの方法でもやはり低活性で低温重合(−10℃〜0℃)が必須であり、重合温度を10℃に上げるだけで、ブロック化効率は10%未満まで低下することが記載されている。そのため工業的に通常用いられる重合温度(50℃〜75℃)でのブロック共重合体の製造は不可能である。さらに低温重合の場合でも、リビング重合性の指標である、ブロック共重合体の分子量分布(Mw/Mn)は1.35以上と狭いといえず、十分に制御されたリビング重合とはなっていない。そのため生成物はほとんどの場合、多量のブロック化されていないポリマーが副生し、後処理工程で不要ポリマーを取り除く分別が必須となるなど工業的には多くの制約がある。 For example, a method using a specific metallocene catalyst has been proposed (see International Publication Nos. WO91 / 12285, WO94 / 21700, etc.). Even in these methods, low activity and low temperature polymerization (-10 ° C to 0 ° C) are essential, and it is described that the blocking efficiency is reduced to less than 10% only by raising the polymerization temperature to 10 ° C. Therefore, it is impossible to produce a block copolymer at a polymerization temperature (50 ° C. to 75 ° C.) usually used industrially. Furthermore, even in the case of low-temperature polymerization, the molecular weight distribution (Mw / Mn) of the block copolymer, which is an index of living polymerizability, cannot be said to be as narrow as 1.35 or more, and it is not a well-controlled living polymerization. . For this reason, most of the products are industrially restricted such that a large amount of unblocked polymer is produced as a by-product, and fractionation for removing unnecessary polymer in the post-treatment process is essential.
このためもし工業的に製造可能な高い温度で、しかも高い重合活性でオレフィン類をリビング重合することのできる方法が出現すればその工業的価値は極めて大きい。 For this reason, if a process capable of living-polymerizing olefins at a high temperature that can be produced industrially and at a high polymerization activity appears, the industrial value is extremely high.
このような状況のもと本出願人は、新しいオレフィン重合用触媒として、サリチルアルジミン配位子を有する遷移金属化合物を見出した。このサリチルアルジミン配位子を有する遷移金属化合物のうち、特定の構造を有するものを用いると、工業的に製造可能な高い温度で、従来知られているリビング重合と比較して非常に高い活性でリビング重合が進行し、ブロック共重合体の製造が可能であることを見出して本発明を完成するに至った。また、そのようなブロック共重合体の製造を効率よく行う方法を発明して、本発明を完成するに至った。

以下に、上記一般式(I)で表される遷移金属化合物の具体的な例を示すが、これらに限定されるものではない。 Specific examples of the transition metal compound represented by the general formula (I) are shown below, but are not limited thereto.
なお、上記例示中、Meはメチル基を、Etはエチル基を、Prはプロピル基を、Buはブチル基を、Phはフェニル基を示す。 In the above examples, Me represents a methyl group, Et represents an ethyl group, Pr represents a propyl group, Bu represents a butyl group, and Ph represents a phenyl group.
このような遷移金属化合物(A)の製造方法は、特に限定されることなく、例えば以下のようにして製造することができる。 The method for producing such a transition metal compound (A) is not particularly limited and can be produced, for example, as follows.
まず、遷移金属化合物(A)を構成する配位子は、サリチルアルデヒド類化合物を、式R1−NH2の第1級アミン類化合物(R1は前記と同義である。)、例えば、アニリン類化合物またはアルキルアミン類化合物と反応させることにより得られる。具体的には、両方の出発化合物を溶媒に溶解する。溶媒としては、このような反応に一般的なものを使用できるが、なかでもメタノール、エタノール等のアルコール溶媒、またはトルエン等の炭化水素溶媒が好ましい。次いで、得られた溶液を室温から還流条件で、約1〜48時間撹拌すると、対応する配位子が良好な収率で得られる。配位子化合物を合成する際、触媒として、蟻酸、酢酸、トルエンスルホン酸等の酸触媒を用いてもよい。また、脱水剤として、モレキュラシーブス、硫酸マグネシウムまたは硫酸ナトリウムを用いたり、ディーンシュタークトラップにより脱水を行うと、反応進行に効果的である。 First, the ligand constituting the transition metal compound (A) is a salicylaldehyde compound, a primary amine compound of the formula R 1 —NH 2 (R 1 is as defined above), for example, aniline. It can be obtained by reacting with an alkyl compound or an alkylamine compound. Specifically, both starting compounds are dissolved in a solvent. As the solvent, those generally used for such a reaction can be used, and among them, an alcohol solvent such as methanol and ethanol, or a hydrocarbon solvent such as toluene is preferable. The resulting solution is then stirred from room temperature under reflux conditions for about 1 to 48 hours to give the corresponding ligand in good yield. When synthesizing the ligand compound, an acid catalyst such as formic acid, acetic acid, and toluenesulfonic acid may be used as a catalyst. Further, when molecular sieves, magnesium sulfate or sodium sulfate is used as a dehydrating agent, or dehydration is performed using a Dean-Stark trap, it is effective for the progress of the reaction.
次に、こうして得られた配位子を遷移金属M含有化合物と反応させることで、対応する遷移金属化合物を合成することができる。具体的には、合成した配位子を溶媒に溶解し、必要に応じて塩基と接触させてフェノキサイド塩を調製した後、金属ハロゲン化物、金属アルキル化物等の金属化合物と低温下で混合し、−78℃から室温、もしくは還流条件下で、約1〜48時間撹拌する。溶媒としては、このような反応に普通のものを使用できるが、なかでもエーテル、テトラヒドロフラン(THF)等の極性溶媒、トルエン等の炭化水素溶媒などが好ましく使用される。また、フェノキサイド塩を調製する際に使用する塩基としては、n−ブチルリチウム等のリチウム塩、水素化ナトリウム等のナトリウム塩等の金属塩や、トリエチルアミン、ピリジン等の有機塩基が好ましいが、この限りではない。 Next, the corresponding transition metal compound can be synthesized by reacting the thus obtained ligand with the transition metal M-containing compound. Specifically, the synthesized ligand is dissolved in a solvent and contacted with a base as necessary to prepare a phenoxide salt, and then mixed with a metal compound such as a metal halide or metal alkylate at a low temperature. The mixture is stirred for about 1 to 48 hours at -78 ° C to room temperature or under reflux conditions. As the solvent, those commonly used for such a reaction can be used. Among them, polar solvents such as ether and tetrahydrofuran (THF), hydrocarbon solvents such as toluene and the like are preferably used. The base used in preparing the phenoxide salt is preferably a metal salt such as a lithium salt such as n-butyllithium, a sodium salt such as sodium hydride, or an organic base such as triethylamine or pyridine. Not as long.
また、化合物の性質によっては、フェノキサイド塩調製を経由せず、配位子と金属化合物とを直接反応させることで、対応する遷移金属化合物を合成することもできる。 Depending on the properties of the compound, the corresponding transition metal compound can be synthesized by directly reacting the ligand with the metal compound without going through the preparation of the phenoxide salt.
さらに、合成した遷移金属化合物中の金属Mを、常法により別の遷移金属と交換することも可能である。また、例えばR1〜R6の何れかがHである場合には、合成の任意の段階において、H以外の置換基を導入することができる。 Further, the metal M in the synthesized transition metal compound can be exchanged with another transition metal by a conventional method. For example, when any of R 1 to R 6 is H, a substituent other than H can be introduced at any stage of the synthesis.
また、遷移金属化合物を単離せず、配位子と金属化合物との反応溶液をそのまま重合に用いることもできる。 Moreover, the reaction solution of a ligand and a metal compound can also be used for polymerization as it is without isolating the transition metal compound.

Polymerization was started by adding 2.5 mmol of methylaluminoxane in terms of aluminum atom, and subsequently adding 0.02 mmol of a titanium compound (1; synthesis example is described in Japanese Patent Application No. 2002-311685). After 5 minutes of reaction at 25 ° C. and complete consumption, 10 ml of 1-hexene was added and reacted for 5 minutes while blowing ethylene gas (50 liter / h). A small amount of methanol was added to stop the reaction, and the reaction product was added to 1 liter of methanol containing a small amount of hydrochloric acid to precipitate a copolymer. The copolymer was filtered, washed with methanol, and dried under reduced pressure at 130 ° C. for 10 hours to obtain 2.193 g of copolymer. The obtained copolymer had Mn (number average molecular weight) of 80,000, Mw / Mn (molecular weight distribution) of 1.26, and 1-hexene content measured by IR was 6.0 mol%. It was.
