Abstract

Provided is a wholly aromatic liquid crystalline polyester resin compound. The wholly aromatic liquid crystalline polyester resin compound includes a wholly aromatic liquid crystalline polyester resin having a high melting point and mica having a predetermined size.

Claims

1. A wholly aromatic liquid crystalline polyester resin compound, the compound comprising 100 parts by weight of a wholly aromatic liquid crystalline polyester resin having a melting point of about 300°

C. to about 450°

C.; and

about 5 parts by weight to about 25 parts by weight of mica having an average particle diameter of about 20 μ

m to about 50 μ

m, wherein the wholly aromatic liquid crystalline polyester resin compound comprises at least a repeating unit derived from an aromatic diamine, an aromatic hydroxylamine and an aromatic amino carboxylic acid.

2. The wholly aromatic liquid crystalline polyester resin compound of claim 1, wherein the wholly aromatic liquid crystalline polyester resin compound further comprising an inorganic filler other than the mica.

3. The wholly aromatic liquid crystalline polyester resin compound of claim 2, wherein the inorganic filler is at least one selected from the group consisting of glass fiber, talc, calcium carbonate, and clay.

4. The wholly aromatic liquid crystalline polyester resin compound of claim 2, wherein an amount of the inorganic filler is about 5 parts by weight to about 90 parts by weight based on 100 parts by weight of the wholly aromatic liquid crystalline polyester resin.
