METHOD FOR PRODUCING THERMOPLASTIC RESIN FILM

摘要

PROBLEM TO BE SOLVED: To provide a thermoplastic resin film having an improved delamination strength and assuming liquid crystallinity during melting. SOLUTION: (1) This method for producing a thermoplastic resin composition film composes irradiating the thermoplastic resin film comprising a thermoplastic resin (A) assuming the liquid crystallinity during the melting as a continuous phase and copolymer (B) having functional groups reactive with the thermoplastic resin assuming the liquid crystallinity during the melting and a structure enabling a cross-linking reaction to proceed by irradiation with electron beams as a dispersed phase with the electron beams at 100-500 kGy. (2) The method for production described in (1) composes irradiating the film with the electron beams in an inert gas atmosphere. (3) In the method for production described in (1) or (2), the thermoplastic resin (A) is a liquid crystal polyester.
