頁、１９８5.１） ポリアリレート樹脂を塩素を含む脂肪族炭化水素系溶剤
に溶解して溶液流延法でキャスティングフイルムを製造
しようとすると、溶剤の乾燥に伴ないフイルムは収縮を
おこし、しわが発生して平らなフイルムを得ることがで
きなかった。Polyarylate resin has heat resistance, impact resistance, chemical resistance,
It has excellent mechanical strength, dimensional stability, etc., and is used as a so-called engineering plastic after being molded by an injection molding method. (Polymer digest, 75
P., 1985.1) When a casting film is produced by a solution casting method by dissolving a polyarylate resin in an aliphatic hydrocarbon solvent containing chlorine, the film shrinks as the solvent dries and wrinkles occur. It could not be obtained and a flat film could not be obtained.
本発明の目的は、上記欠点に鑑み、溶液流延法により、
ポリアリレート樹脂の平らなキャスティングフイルムを
得ることのできる製造方法を提供することにある。The object of the present invention is, in view of the above-mentioned drawbacks, by a solution casting method,
It is an object of the present invention to provide a manufacturing method capable of obtaining a flat casting film of polyarylate resin.
本発明で用いる塩素を含む脂肪族炭化水素系溶剤として
は、たとえばジクロロメタン、ジクロロエタン、トリク
ロロエタン、クロロホルム、四塩化炭素、等があげられ
る。Examples of the chlorine-containing aliphatic hydrocarbon solvent used in the present invention include dichloromethane, dichloroethane, trichloroethane, chloroform and carbon tetrachloride.

アリレート樹脂１００重量部に対し0.５〜３０重量部添
加される。If the amount of the organic compound added is small, the crosslinking will be insufficient, and the film will shrink during or after drying, and if it is large, the film will be hard and brittle, and therefore 0.5% relative to 100 parts by weight of the polyarylate resin. ~ 30 parts by weight are added.
本発明においてはポリアリレート樹脂と上記有機化合物
を上記溶剤に溶解し、ガラス板等の基板上に流延し乾燥
すればよい。In the present invention, the polyarylate resin and the organic compound may be dissolved in the solvent, cast on a substrate such as a glass plate and dried.
本発明においては、ポリアリレート樹脂の末端基として
残っている水酸基と上記有機化合物のイソシアネート基

れるので、架橋は常温でも進行するが、架橋が充分進む
ように乾燥時に加熱するのが好ましく、たとえば８０〜
１５０℃で１０〜１２０分加熱乾燥するのが好ましい。In the present invention, the shrinkage of the film is suppressed by the reaction of the hydroxyl groups remaining as the terminal groups of the polyarylate resin with the isocyanate groups of the organic compound, so that the crosslinking proceeds even at room temperature, but the crosslinking proceeds sufficiently. It is preferable to heat at the time of drying so that, for example, 80 to
It is preferable to heat-dry at 150 ° C. for 10 to 120 minutes.
尚上記溶液をガラス板等の基板上に流延し、常温で乾燥
した後フイルムを剥すことなく加熱してもよい。The solution may be cast on a substrate such as a glass plate, dried at room temperature, and then heated without peeling the film.

ク、ブラファイト、酸化亜鉛、タルク、炭酸カルシウ
ム、酸化チタン等の充填剤や着色剤を添加してもよい。Although the polyarylate resin film obtained by the above-mentioned production method is transparent, it is colored or opaque to the film, or in order to impart conductivity, carbon black, brafite, zinc oxide, talc, calcium carbonate, Fillers such as titanium oxide and colorants may be added.
本発明の構成は上述の通りであるから、耐熱性、耐衝撃
性、耐薬品性、機械特性、耐候性、寸法安定性のすぐれ
た平らなキャスティングフイルムを得ることができる。Since the constitution of the present invention is as described above, it is possible to obtain a flat casting film having excellent heat resistance, impact resistance, chemical resistance, mechanical properties, weather resistance and dimensional stability.
