Title:
METHOD FOR MANUFACTURING THERMOPLASTIC RESIN FILM, THERMOPLASTIC RESIN FILM, AND LIQUID CRYSTAL DISPLAY ELEMENT SUBSTRATE
Document Type and Number:
Japanese Patent JP2002166459
Kind Code:
A
Abstract:
To provide a method for manufacturing a thermoplastic resin film capable of being used as a liquid crystal element substrate having excellent optical characteristics.
In the method for manufacturing the thermoplastic resin film by laminating a thermoplastic resin B on both surfaces of a thermoplastic resin A with a glass transition temperature of ≥150°C in a peelable state by melt coextrusion and peeling the laminated thermoplastic resin B, at least one compound selected from polysiloxane, a metal salt of a fatty acid, alkyl sulfate and a fluorine modified polymer is added in an amount of 5-5,000 ppm to perform melt extrusion.
