MANUFACTURE OF ISOTROPIC LIQUID CRYSTAL POLYMER FILM AND LAMINATE THEREOF, AND ISOTROPIC LIQUID CRYSTAL POLYMER FILM AND LAMINATE THEREOF

摘要

PROBLEM TO BE SOLVED: To provide the industrially advantageous manufacturing method of isotropic liquid crystal polymer film having its anisotropy remarkably dissolved and of its laminate and the isotropic liquid crystal polymer film and its laminate. ;SOLUTION: By thermocompression welding thermoplastic resin film under pressure and heat on both the sides of anisotropic liquid crystal polymer film, which consists of liquid crystal polymer and its poly polymer alloy and the greater part of which is orientated to one direction, a laminate, in which the resin film is softly joined releasably to the liquid crystal polymer film. After the obtained laminate is stretched normal or parallel to the direction of orientation of the liquid crystal polymer and then stretched normal to the direction of orientation of the liquid crystal polymer, the obtained laminate stretched matter is cooled down and finally the resin film is separated from the cooled laminate stretched matter.;COPYRIGHT: (C)1997,JPO
