Document Type and Number:
WIPO Patent Application WO/2018/056294
Kind Code:
A1
Abstract:
Provided is a liquid crystal polyester resin composition that contains 3-25 parts by weight of (B) a metal-based additive relative to 100 parts by weight of (A) a fully aromatic liquid crystal polyester. The fully aromatic liquid crystal polyester (A) contains a total of 60-77 mol.% of structural units derived from hydroxybenzoic acid and structural units derived from terephthalic acid relative to 100 mol.% of all the structural units in the fully aromatic liquid crystal polyester. The metal-based additive (B) comprises a metal selected from among copper, tin, cobalt, nickel and silver, or a compound containing such a metal. Provided is the liquid crystal polyester resin composition which exhibits excellent moldability of a molded article surface to a metal part, excellent adhesion between a molded article and a metal part when the temperature changes, and excellent molded article surface hardness. Also provided is a molded article comprising same.
