There has been no examination of molding, physical properties, etc. of the composition and copolymer fibers.

また非特許文献2にはポリベンゾビスチアゾール分子鎖中にハロゲン原子を導入し焼成時に発生するラジカルにより分子間結合を導入する試みがなされており、確かにシェアモジュラスの向上が見られるがポリベンゾビスオキサゾール、や水酸基を有するアゾール系ポリマーやピリジン環を有するアゾール系ポリマーとの共重合の報告例はない。   In Non-Patent Document 2, an attempt is made to introduce a halogen atom into a polybenzobisthiazole molecular chain and introduce an intermolecular bond by a radical generated at the time of firing. There is no report of copolymerization with bisoxazole, an azole polymer having a hydroxyl group, or an azole polymer having a pyridine ring.

反応は、溶媒中で行う反応、無溶媒の加熱溶融反応のいずれも採用できるが、例えば、後述する反応溶媒中で攪拌下に加熱反応させるのが好ましい。反応温度は、50℃から500℃が好ましく、100℃から350℃がさらに好ましい。50℃より温度が低いと反応が進みにくく、500℃より温度が高いと分解等の副反応が起こりやすくなるためである。反応時間は温度条件にもよるが、通常は1時間から数十時間である。反応は加圧下から減圧下で行うことができる。   For the reaction, either a reaction performed in a solvent or a solvent-free heat-melting reaction can be adopted. The reaction temperature is preferably 50 ° C to 500 ° C, more preferably 100 ° C to 350 ° C. This is because if the temperature is lower than 50 ° C., the reaction hardly proceeds, and if the temperature is higher than 500 ° C., side reactions such as decomposition tend to occur. Although the reaction time depends on temperature conditions, it is usually 1 hour to several tens of hours. The reaction can be carried out from under pressure to under reduced pressure.

Examples of transesterification catalysts used in the present invention include antimony compounds such as antimony trioxide, stannous acetate, tin chloride, tin octylate, tin compounds such as dibutyltin oxide and dibutyltin diacetate, and alkaline earth metal salts such as calcium acetate. And phosphorous acid such as alkali metal salts such as sodium carbonate and potassium carbonate, diphenyl phosphite and triphenyl phosphite.

反応に際しては、必要に応じて溶媒を用いることが出来る。好ましい溶媒としては1―メチル―2−ピロリドン、1―シクロヘキシル−2―ピロリドン、ジメチルアセトアミド、ジメチルスルホキシド、ジフェニルエーテル、ジフェニルスルホン、ジクロロメタン、クロロロホルム、テトラヒドロフラン、o−クレゾール、m−クレゾール、p−クレゾール、りん酸、ポリりん酸等を挙げることが出来るがこれに限定されるものではない。
剛直系複素環共重合体の分解及び着色を防ぐため、反応は乾燥した不活性ガス雰囲気下で行うことが望ましい。
In the reaction, a solvent can be used as necessary. Preferred solvents include 1-methyl-2-pyrrolidone, 1-cyclohexyl-2-pyrrolidone, dimethylacetamide, dimethyl sulfoxide, diphenyl ether, diphenyl sulfone, dichloromethane, chloroform, tetrahydrofuran, o-cresol, m-cresol, p-cresol, Although phosphoric acid, polyphosphoric acid, etc. can be mentioned, it is not limited to this.
In order to prevent decomposition and coloring of the rigid heterocyclic copolymer, the reaction is desirably performed in a dry inert gas atmosphere.
