| titleOfInvention | Manufacturing method of LCP extruded film |
| abstract | PROBLEM TO BE SOLVED: To provide a novel method for producing an LCP extruded film, which can significantly reduce the high orientation of a thermoplastic liquid crystal polymer, which has been difficult to avoid by conventional extrusion molding. SOLUTION: A resin composition A for a first surface layer containing a thermoplastic resin, a resin composition B for a central layer containing a thermoplastic liquid crystal polymer, and a resin composition C for a second surface layer containing a thermoplastic resin. , The resin composition A, the resin composition B, and the resin composition C under the conditions of a shear stress of 40 kPa or less and a drawdown ratio of 3.5 or less from the two-kind three-layer extruder. A step of coextruding to form a two-kind three-layer film having the first surface layer, the central layer, and the second surface layer at least in this order, and removing the first and second surface layers from the two-kind three-layer film. A method for producing an LCP extruded film, which comprises obtaining an LCP extruded film having a thickness of 15 μm or more and 300 μm or less. [Selection diagram] Fig. 1 |
