THERMOPLASITC LIQUID CRYSTAL POLYMER FILM AND METHOD FOR PRODUCING SAME

摘要

A thermoplastic liquid polymer film and a method of producing the same are provided. The method includes preparing a thermoplastic liquid crystal polymer film that has dielectric constants of not larger than 3.25 both in an MD direction and in a TD direction; and performing drawing of the film while heating the film at a temperature in a range from a temperature (Td - 60°C) that is 60°C lower than a heat deformation temperature (Td) of the film to a temperature (Td - 5°C) that is 5°C lower than Td. The temperature of the heating during the drawing of the film may be in a range from a temperature (Td - 40°C) that is 40°C lower than a heat deformation temperature (Td) of the film subjected to the drawing to a temperature (Td - 10°C) that is 10°C lower than Td.
