【発明が解決しようとする課題】
特開平８−９０５７０号公報に記載された方法は、熱可塑性液晶ポリマーフィルムを製造する段階、同フィルムを別途調製した支持体と密着または接着させて積層構造物とする段階、得られた積層構造物を熱処理する段階、および熱処理後のフィルムを支持体から分離する段階からなる。
しかして本発明は、かかる方法を改良し、耐摩耗性が改良され、熱膨張係数が調整された熱可塑性液晶ポリマーフィルムをより能率的に製造できる方法およびそのための装置を提供することを課題とする。[0005]
[Problems to be solved by the invention]
The method described in JP-A-8-90570 comprises the steps of producing a thermoplastic liquid crystal polymer film, adhering or adhering the film to a separately prepared support to form a laminate structure, and the obtained laminate structure Heat treating the article and separating the heat treated film from the support.
Therefore, the object of the present invention is to provide a method and an apparatus therefor which can improve such a method, and can more efficiently manufacture a thermoplastic liquid crystal polymer film having an improved abrasion resistance and a controlled thermal expansion coefficient. Do.

なお、３層の共押出ダイスを使用して熱可塑性液晶ポリマーフィルム（中間層）と他の樹脂（外層）からなる３層フィルムを製造し、中間層の熱可塑性液晶ポリマーフィルムを取り出すことからなる熱可塑性液晶ポリマーフィルムの製造方法が、特開昭６３−３１７２９号公報および特開平２−１７８０１６号公報に記載されているが、Ｔダイによる押出成形を利用したものであって、インフレーション法ではない点において、本発明の方法とは相違する。また、上記の公報には得られた３層フィルムに対して熱処理を行うことについての記載はない。[0007]
Incidentally, to produce a three-layer film made of a thermoplastic liquid crystal polymer film using a coextrusion die having a three-layer (intermediate layer) and another resin (outer layer), consisting of taking out the thermoplastic liquid crystal polymer film of the intermediate layer Although the manufacturing method of a thermoplastic liquid crystal polymer film is described in Unexamined-Japanese-Patent No. 63-31729 and Unexamined-Japanese-Patent No. 2-178016, it utilizes the extrusion molding by T-die, Comprising: It is not an inflation method. In this respect, it differs from the method of the present invention. Moreover, there is no description about heat-processing with respect to the obtained three-layer film in said gazette.

本発明の製造方法においては、積層構造のフィルムを上記のように熱処理した後、同フィルムの熱可塑性液晶ポリマー層と高融点ポリマーの層を分離し、目的とする熱可塑性液晶ポリマーフィルムを得る。分離は、Ｔ剥離法、９０°剥離法、１８０°剥離法等の剥離法などの公知の方法により達成することができる。[0026]
In the production method of the present invention, after the film of the laminated structure is heat-treated as described above, the thermoplastic liquid crystal polymer layer and the high melting point polymer layer of the film are separated to obtain the desired thermoplastic liquid crystal polymer film. The separation can be achieved by a known method such as a peeling method such as a T peeling method , a 90 ° peeling method , or a 180 ° peeling method.
