Title:
LIQUID CRYSTAL POLYESTER RESIN COMOSITION, LIQUID CRYSTAL POLYESTER FIBERS, FIBER STRUCTURE AND MELT MOLDED BODY
Document Type and Number:
WIPO Patent Application WO/2022/113803
Kind Code:
A1
Abstract:
The present invention provides: a liquid crystal polyester resin composition which is able to be suppressed in the generation of a gas during heating and melting, and which is capable of producing a high-quality molded body that has less air bubbles; and liquid crystal polyester fibers. The liquid crystal polyester resin composition contains a liquid crystal polyester and at least one metal element that is selected from the group consisting of metal elements in groups 8 to 11 of the periodic table. The liquid crystal polyester fibers are formed from the liquid crystal polyester resin composition. For example, the liquid crystal polyester fibers may have a total carboxy end group amount (total CEG amount) of 5.0 meq/kg or less.
