Title:
METHOD FOR PRODUCING LIQUID CRYSTAL POLYMER COMPOSITION, AND MOLDED ARTICLE
Document Type and Number:
WIPO Patent Application WO/2013/069777
Kind Code:
A1
Abstract:
A method for producing a liquid crystal polymer composition includes: using a melt-kneading extrusion machine provided with a nozzle, a cylinder, and a screw positioned within the cylinder; obtaining a mixture by supplying component (A), a liquid crystal polymer, and component (B), a magnetic filler obtained by subjecting a composite material comprising a ceramic powder and a soft-magnetic metal powder to thermal processing in an inert gas atmosphere, to the cylinder via the supply port in the cylinder, and melt-kneading the components (A, B); extruding the mixture via the nozzle to the exterior of the melt-kneading extrusion machine; and cooling the mixture at a cooling rate of 60°C or less per second. Also, a molded article is obtained by molding the liquid crystal polymer composition obtained using this production method.
